The 2025 Pacific hurricane season is the most active Pacific hurricane season on record, surpassing the record set previously by the 1992 season. Featuring a total of 34 tropical depressions, a record high 31 named storms, 14 hurricanes, and 8 majors, the season also featured a total of 8 landfalls, all occurring in Mexico. The season officially began on May 15 in the Eastern Pacific, and on June 1 in the Central Pacific; they both ended on November 30. These dates tend to limit the bounds of formation of tropical cyclones in the Eastern and Central Pacific. However, tropical cyclones can form any time of year, as shown by the formation of Tropical Storm Alvin 4 days before the official start of the season and the formation of erratic Tropical Storm Pena in the Central Pacific in early December.

The season started off weak, with the exception of Hurricanes Cosme and Dalila which were both Category 2 storms with similar tracks in mid-June. Hurricane Gil became the season's first major hurricane on July 17, and Tropical Storm Henriette made the season's first of eight landfalls in Mexico shortly after. In early August, Hurricane Kiko developed simultaneously with Tropical Depression Twelve-E. While the latter eventually traversed over mountainous Mexico, Kiko continued to rapidly intensify into a Category 5 storm. Hurricane Kiko steadily weakened to a Category 2 hurricane before beginning to fluctuate in intensity before attaining tertiary peak of 155 mph as it traversed south of Hawai'i. Tropical Storm Mario developed in the far eastern sector of the basin, then slowly crawling over Mexico while looping and weakening briefly. It became a tropical storm once again and then dissipated quickly due to slow movement, land interaction, and its poor organization. Tropical Storm Priscilla also originated in the same region, but lasted significantly less time and was extremely sheared.

September 2025 began with Hurricane Octave and Tropical Storm Priscilla. Tropical Storm Raymond developed near the tip of the Baja California Peninsula and eventually made landfall in Mexico near Los Mochis. Hurricane Tico developed from the remnants of Hurricane Jerry in the Atlantic and became an extremely strong Category 4 storm before making landfall near Mazatlán, Mexico as a Category 3. To start October, Tropical Depression Twenty-Three-E was a short lived depression that impacted the Baja California Peninsula, and Tropical Storm Xina paralleled the Mexican coastline. Hurricanes York and Zelda became exceptionally strong late season Category 4 storms, the former striking Mexico at its secondary peak.

The formation of Tropical Storm Alpha late on October 23 marked the first time in history the Greek alphabet was used in the Eastern Pacific. Tropical Storms Beta and Gamma were weak and remained out to sea in early-to-mid November. On November 20, Hurricane Delta developed south of Mexico, moving swiftly to the northwest. The storm rapidly intensified into a Category 5 hurricane on November 21, becoming the latest recorded Category 5 storm in the Eastern Pacific. Delta rapidly weakened and dissipated two days later. To end off the season, Subtropical Storm Pena developed from a Kona low/extratropical system in the Central Pacific on December 4. It transitioned to a tropical storm the next day, looping and moving south. After completing its erratic track, Pena turned extratropical as it advanced quickly to the northwest on December 10.

Systems

Tropical Storm Alvin

Tropical storm (SSHWS)
Alvin 2019-06-26 2050Z.jpg Alvin Track EPAC 2025 - CycloneMC.png
DurationMay 11 – May 15
Peak intensity70 mph (110 km/h) (1-min)  990 mbar (hPa)

A tropical wave emerged off the coast of Coast Rica on May 8. As it traversed to the west it continued to organize, and on May 11 the system developed into Tropical Depression One-E. During the next 24 hours, the system did not intensify considerably. At 06z May 12, One-E was upgraded to a tropical storm due to ASCAT supporting upwards of 35 kt, earning the name Alvin. Alvin strengthened gradually before nearing hurricane intensity, however it fell just short. Alvin began weakening after peaking at 70 mph, eventually becoming a tropical depression on May 15, degenerating into a remnant low by 18z on May 15.

Tropical Storm Barbara

Tropical storm (SSHWS)
Barbara Sim EPAC 2025 - CycloneMC.jpg Barbara Track EPAC 2025 - CycloneMC.png
DurationJune 1 – June 2
Peak intensity40 mph (65 km/h) (1-min)  1007 mbar (hPa)

On May 31, a mesoscale convective system developed over Mexico and moved offshore shortly after. The system quickly gained a center and was designated Tropical Depression Two-E. Although sheared and disorganized, the system was able to strengthen and was upgraded to Tropical Storm Barbara as the center began to separate from the convection. Peaking at formation, Barbara then degraded and was reduced to a tropical depression once again as it slowly crawled away from the Baja California Peninsula. It dissipated on June 2 without major impacts on the Peninsula.

Hurricane Cosme

Category 2 hurricane (SSHWS)
Linda 2021-08-13 2015Z.jpg Cosme Track EPAC 2025 - CycloneMC.png
DurationJune 10 – June 16
Peak intensity105 mph (165 km/h) (1-min)  976 mbar (hPa)

A tropical wave developed to the south of Panama and close to the coast of Colombia on June 5. It moved to the west slowly at first, before increasing in forward speed after passing Central America. On June 9, the system had developed an identifiable center, but nothing organized or fit enough for an upgrade to a tropical depression. By the next day the center had collocated well enough for it to become Tropical Depression Three-E, and the depression intensified into Tropical Storm Cosme by the end of the day. Cosme promptly organized and developed an eye feature, intensifying into a Category 1 hurricane early on June 12. It peaked as a Category 2 hurricane with winds of 105 mph and a pressure of 976 mbar (28.82 inHg). After sustaining Category 2 winds for a decent amount of time, Cosme began to deteoriate and weaken. It weakened to a tropical storm at 00z on June 15, and a remnant low 24 hours later. The remnants of Cosme quickly dissipated later on June 16.

Hurricane Dalila

Category 2 hurricane (SSHWS)
Elida 2020-08-10 2015Z.jpg Dalila Track EPAC 2025 - CycloneMC.png
DurationJune 14 – June 20
Peak intensity110 mph (175 km/h) (1-min)  975 mbar (hPa)

The precursor to Dalila formed near the border of Guatemala and El Salvador on June 12. Originally stationary, the system had a clear sign of a mid-level center as it crawled to the southwest. By June 14, it had gained tropical characteristics and had developed a low-level center, prompting an upgrade to Tropical Depression Four-E. The depression struggled to intensify primitively, but eventually became a tropical storm at 06z on June 15. Dalila continued to intensify at a similar rate to Cosme, becoming a hurricane the next day. Dalila lacked a clear eye during its tenure as a hurricane yet continued to strengthen steadily. The storm peaked as a Category 2 hurricane with winds of 110 mph and a pressure of 975 mbar (28.79 inHg). Dalila tracked just south of the Baja California Peninsula and just southwest of Mexico's coast. It weakened to a Category 1 hurricane by 00z on June 19, and a tropical storm by 18z the same day. It degenerated into a remnant low at 18z on June 20, and the National Hurricane Center stopped observing the system shortly after.

Tropical Storm Erick

Tropical storm (SSHWS)
03E 2020-06-24 2225Z.jpg Erick Track EPAC 2025 - CycloneMC.png
DurationJune 28 – July 1
Peak intensity45 mph (75 km/h) (1-min)  999 mbar (hPa)

The tropical wave that eventually became Erick emerged off of the coast of Africa on June 20. It quickly traversed the deep Atlantic before moving over northern South America. It emerged into the Eastern Pacific by June 24. The system was marked by the National Hurricane Center for potential development over the coming days. By June 28, deep convection had concentrated itself around the center of the system, leading to the forming of tropical depression. Five-E quickly intensified into Tropical Storm Erick as the storm moved west uninterestingly. The storm began to deteriorate due to northerly shear. It left the center of Erick exposed and cause the convection to wane and by June 30, Erick had weakened to a tropical depression. Increasing shear led to Erick weakening to a remnant low and the eventual death of its remnants on July 1.

Tropical Depression Six-E

Tropical depression (SSHWS)
04E 2020-06-29 2050Z.jpg 06E Track EPAC 2025 - CycloneMC.png
DurationJuly 7 – July 8
Peak intensity35 mph (55 km/h) (1-min)  1006 mbar (hPa)

A tropical wave and its interaction with the monsoon trough generated a tropical depression (Six-E) far to the south of the Baja California Peninsula on July 7. It was short lived, as its convection waned repeatedly and struggled to organize further. Tropical Depression Six-E opened up into a trough of low pressure the next day.

Tropical Storm Flossie

Tropical storm (SSHWS)
Iselle 2020-08-26 2105Z.jpg Flossie Track EPAC 2025 - CycloneMC.png
DurationJuly 12 – July 14
Peak intensity40 mph (65 km/h) (1-min)  1004 mbar (hPa)

A tropical wave materialized over the open Atlantic on July 3. It travelled west and remained disorganized. It entered the Eastern Pacific on July 6 and moved to the west until it became Tropical Depression Seven-E on July 12. Despite being in a slightly hostile environment with a slightly elongated circulation, Seven-E strengthened to a tropical storm twelve hours after formation, earning the name Flossie. Flossie's ornery environment eventually overtook it, weakening it to a depression only twelve hours after being named. Holding onto its sheared convection, Flossie eventually became a remnant low on July 14. It dissipated quickly after and the National Hurricane Center ceased monitoring it.

Hurricane Gil

Category 4 hurricane (SSHWS)
Linda 2021-08-14 2110Z.jpg Gil Track EPAC 2025 - CycloneMC.png
DurationJuly 15 – July 20
Peak intensity130 mph (215 km/h) (1-min)  948 mbar (hPa)

On July 11, an area of low pressure developed to the south of the Gulf of Tehuantepec. Throughout the next several days, the system gradually developed and eventually was upgraded to Tropical Depression Eight-E on July 15. Eight-E quickly strengthened into Tropical Storm Gil in just under six hours after formation. Twenty-four hours later, Gil became a Category 1 hurricane as it entered a period of quick intensification. It strengthened to the first major hurricane of the season at 18z on July 16 and then stalled at Category 3 intensity for another eighteen hours. Gil's eye continued to warm, leading to its increase in intensity as it peaked as a Category 4 hurricane with winds of 130 mph and a pressure of 948 mbar (27.99 inHg).

This peak was brief as Gil's convection swiftly became anemic, warming slightly as the eye fell apart. Weakening below major status by 12z July 18, its center continued to become exposed and the convection displaced. The next day, Gil weakened to a tropical storm as the center was entirely devoid of deep convection. Gil continued to rapidly weaken until the National Hurricane Center declared it a remnant low at 06z July 20. The low pressure lingered for days before becoming awfully elongated and weak. It eventually dissipated fully on July 22.

Tropical Storm Henriette

Tropical storm (SSHWS)
Pilar 2017-09-24 1740Z.jpg Henriette Track EPAC 2025 - CycloneMC.png
DurationJuly 16 – July 18
Peak intensity50 mph (85 km/h) (1-min)  1000 mbar (hPa)

An area of weak low pressure formed near the Gulf of Tehuantepec on July 13. The system began to slowly crawl to the west while undergoing slow tropical cyclogenesis. Tropical Depression Nine-E developed early on July 16, heading northwest. Late that same day, it strengthened into a tropical storm, earning the name Henriette. Undeterred by hostile conditions ahead of it and land interaction with the Mexican coast, the National Hurricane Center anticipated a near hurricane landfall in Mexico from Henriette, prompting hurricane watches and tropical storm warnings stretching from Puerto Vallarta to Mazatlan. Henriette unexpectedly struggled to intensify once it was named, skirting the coast slightly. It then strengthened quickly to 50 mph, reaching its peak as it briefly slowed down. Tropical Storm Henriette made landfall just west of San Blas, Nayarit as a 45 mph system, and quickly moved inland while weakening. Henriette was last traced as a tropical system at 12z on July 18.

Henriette delivered heavy amounts of rain to portions of Jalisco and Colima as a tropical depression and newly named storm, and Nayarit as it made landfall on July 18. The storm killed 9 in total. Henriette caused landslides, mudslides, and flash flooding that isolated the town of San Blas for up to four days after landfall. Damage totalled $67 million USD ($1.45 billion MX).

Tropical Storm Ivo

Tropical storm (SSHWS)
Enrique 2009-08-04 2120Z.jpg Ivo Track EPAC 2025 - CycloneMC.png
DurationJuly 25 – July 31
Peak intensity70 mph (110 km/h) (1-min)  991 mbar (hPa)

On July 20, a tropical disturbance located in the open Eastern Pacific was flagged by the National Hurricane Center for possible development as it traversed and continued westward slowly. On July 24, the system had organized quickly, with deep convection surrounding the center. However, the center was not yet closed. Early the next day, the National Hurricane Center had determined through ASCAT and satellite imagery that the circulation of the then-invest was closed and tight and that the system had attained gale force winds. Tropical Storm Ivo began a period of rapid intensification soon after becoming a tropical storm, yet this process was halted after dry air entered the tropical storm. Ivo peaked with winds of 70 mph and a central pressure of 991 mbar (29.26 inHg) late on July 25. Ivo's convection waned repeatedly as a result of dry air intrusion, but it did not weaken amidst the hostile environment. However, Ivo's luck began to ran out as it began weakening late on July 26 as shear eventually began to plunge itself towards the struggling storm. Ivo weakened to a tropical depression by mid-day the next day. Ivo's feeble tropical depression phase ended shortly after the system entered the Central Pacific, almost immediately becoming a remnant low on July 28.

The convection associated with the remnants of Ivo began reorganizing and was redesignated as Tropical Depression Ivo on July 30. The system was severely sheared, which led to it's final demise early on July 31.

Hurricane Juliette

Category 1 hurricane (SSHWS)
Guillermo.A2009225.2115.250m.jpg Juliette Track EPAC 2025 - CycloneMC.png
DurationAugust 1 – August 7
Peak intensity90 mph (150 km/h) (1-min)  973 mbar (hPa)

On July 19, a tropical wave exited the coast of Africa and travelled across the Atlantic. It entered the Eastern Pacific on July 27. The wave was then monitored for tropical development over the coming days as it showed increasing signs of organization with plentiful model support. On August 1, the system was designated as Tropical Depression Eleven-E as the circulation closed and the system strengthened to 30 mph (45 km/h). The system entered a period of rapid intensification and became Tropical Storm Juliette later the same day. Less than a day later, Juliette became a Category 1 hurricane, and reached winds of 90 mph and a central pressure of 973 mbar (28.73 inHg). Juliette then suffered a similar fate to Tropical Storm Ivo a few days prior, with the system ingesting some dry air. This caused several fluctuations and stalls in intensity. Juliette remained a Category 1 hurricane until it finally weakened to tropical storm status on August 5. As Juliette's convection waned it weakened to a tropical depression late on August 6, and became a remnant low 24 hours later. The naked swirl lingered in the open ocean for several days before completely dissipating on August 10.

Tropical Depression Twelve-E

Tropical depression (SSHWS)
Ileana 2018-08-06 2045Z (alternate).jpg 12E Track EPAC 2025 - CycloneMC.png
DurationAugust 3 – August 4
Peak intensity35 mph (55 km/h) (1-min)  1004 mbar (hPa)

A cluster of thunderstorms began to show gradual development after forming on August 1. The system became Tropical Depression Twelve-E alongside Tropical Depression Thirteen-E (which would eventually become Hurricane Kiko) on August 3. Due to interaction with the strengthening Tropical Storm Kiko to its southwest, the system was steered into Mexico quickly. It travelled and nearly paralleled the coast before dissipating as it moved inland for the second time on August 4. Twelve-E soon became untraceable as it moved further inland.

Hurricane Kiko

Category 5 hurricane (SSHWS)
John 2018-08-06 2045Z Walaka eye.png Kiko Track EPAC 2025 - CycloneMC.png
DurationAugust 3 – August 20
Peak intensity165 mph (270 km/h) (1-min)  924 mbar (hPa)

A small disturbed area of thunderstorms developed alongside the precursor to Tropical Depression Twelve-E on August 2. The cluster rapidly developed a low level center and was designated Tropical Depression Thirteen-E simultaneously with Tropical Depression Twelve-E. Rapid intensification ensued as the system began to intensify into Tropical Storm Kiko just 6 hours later. An eye feature began to develop as the system neared hurricane intensity later the same night. By 00z on August 4, Kiko became a hurricane and continued to rapidly strengthen. Kiko eventually was upgraded to a Category 4 hurricane as a well-rounded eye became prominent on satellite imagery. The intensification capped off when Kiko became a 165 mph (270 km/h) Category 5 storm, with a central pressure of 924 mbar (27.29 inHg). Kiko maintained Category 5 intensity for almost 48 hours, before it began to slowly weaken as it turned west-southwest. Hurricane Kiko was downgraded to a Category 4 storm at 00z on August 7. Kiko bottomed out as a Category 2 storm before reintensifying once again. Kiko briefly reached a secondary peak as a Category 3 hurricane with winds of 120 mph (195 km/h) on August 10. It began fluctuating in intensity once again, this time reaching a minimum of 80 mph (130 km/h) as a Category 1 hurricane.

Hurricane Kiko crossed into the Central Pacific as a strengthening Category 1 hurricane on August 13, and became a Category 2 shortly after entering the basin. Twelve hours later, Kiko became a major hurricane for the third time in its life. Reaching a tertiary peak of 155 mph (250 km/h) with a central pressure 931 mbar (27.49 inHg), Kiko passed well to the south of Hawaii, taking a similar path to Hurricane Lane of 2018. On August 16, shear finally took hold of Kiko and caused the cyclone to begin weakening. By the 18th, Kiko had weakened to a tropical storm and was being steered to the north. The outer bands of lopsided Tropical Storm Kiko caused heavy rains in the Northwestern Hawaiian Islands, but no major damage or casualties were recorded. Early on August 20, Kiko was declared post-tropical as its remnant continued to move north into unfavorable and non-tropical regions of the Pacific. Kiko's post-tropical carcass became untraceable on August 22.

Tropical Storm Nolo

Tropical storm (SSHWS)
Ema 2019-10-12 1255Z.jpg Nolo Track CPAC 2025 - CycloneMC.png
DurationAugust 4 – August 7
Peak intensity60 mph (95 km/h) (1-min)  997 mbar (hPa)

An area of disturbed weather formed into Tropical Depression Fourteen-E on August 4. It moved into the Central Pacific and earned the name Nolo the next day. It quickly intensified into a 60 mph (95 km/h) storm before weakening as convection waned severely. Nolo became post-tropical on August 7.

Hurricane Lorena

Category 4 hurricane (SSHWS)
Kiko 2019-09-15 1825Z.jpg Lorena Track EPAC 2025 - CycloneMC.png
DurationAugust 11 – August 19
Peak intensity130 mph (215 km/h) (1-min)  946 mbar (hPa)

On August 8, a cluster of thunderstorms with a broad mid-level center began to consolidate off the coast of Central America. As the system moved northwest, a low-level center formed and closed, leading to the formation of Tropical Depression Fifteen-E on August 11. The depression struggled to organize at first but soon began to slowly intensify, strengthening into Tropical Storm Lorena the next day. The system did not rapidly intensify despite warmer waters and low shear. Instead, Lorena faced intense amounts of dry air also entering from the Atlantic. As Lorena flushed the dry air out of the system's core, intensification began. It became a hurricane late on August 13, and was upgraded to a Category 2 hurricane eighteen hours later. The aforementioned dry air once again disrupted Lorena's core, but it made a quick comeback as convection rapidly fired around its core. After Lorena briefly weakened to a Category 1, the hurricane entered a period of rapid intensification and became a low-end Category 4 storm on August 16. This victory with the dry air was short lived, as colder waters also began to take a toll on the system. Lorena weakened due to the cooler sea surface temperatures and drier air began to take advantage of Lorena's initial weakening. By 18z on August 17, Lorena had weakened to a tropical storm, as convection was hanging on by a thread. Lorena continued northwest, becoming post-tropical on August 19.

Tropical Storm Mario

Tropical storm (SSHWS)
01E 2016-06-06 1935Z.jpg Mario Track EPAC 2025 - CycloneMC.png
DurationAugust 14 – August 20
Peak intensity45 mph (75 km/h) (1-min)  1002 mbar (hPa)

A tropical wave entered the Eastern Pacific from the Gulf of Mexico on August 10. It continued to gradually develop until it became Tropical Depression Sixteen-E on August 14. Six hours later, Sixteen-E became a tropical storm, earning the name Mario. the storm slowly crawled to the north and remained weak as it approached the Mexican coastline. Its disorganized nature lead to flooding emergencies and landslides over the next several days, peaking as a 45 mph (75 km/h) tropical storm before barely making landfall on August 15. Mario weakened to a tropical depression after lingering on the coastline, but soon restrengthened as it moved south again, however not gaining much strength. Mario, extremely disorganized, once again weakened to a tropical depression along the coast of Mexico, and then shortly lost all cyclonic nature before dissipating on August 20.

Mario caused a total of $≥342 million in damages, due to flooding, landslides, and storm surge as it stalled off the coast of Mexico. 24 casualties were reported as well.

Hurricane Olana

Category 1 hurricane (SSHWS)
Olana Sim CPAC 2025 - CycloneMC.jpg Olana Track CPAC 2025 - CycloneMC.png
DurationAugust 18 – August 21
Peak intensity75 mph (120 km/h) (1-min)  990 mbar (hPa)

A highly disturbed ITCZ led to the formation of a low pressure well into the Central Pacific on August 14. It slowly crawled to the north-northwest, struggling to develop. By August 18, the CPHC had determined that the system had indeed formed into a tropical storm, albeit late, earning the designation Tropical Storm Olana. Olana continued to organize, gaining size and strength as it moved north. Olana strengthened into a low-end Category 1 hurricane late on August 19. Olana's large size caused isolated showers in Hawaii. It soon began to undergo an extratropical transition, quickly becoming post-tropical on August 21.

Hurricane Narda

Category 1 hurricane (SSHWS)
Enrique 2021-06-26 2030Z.jpg Narda Track EPAC 2025 - CycloneMC.png
DurationAugust 26 – August 31
Peak intensity85 mph (140 km/h) (1-min)  983 mbar (hPa)

A large area of disturbed thunderstorms developed to the south of Guatemala on August 25. It quickly organized and scatterometer (ASCAT) scans displayed a well organized center with sustained winds just below tropical storm-force, prompting an upgrade to Tropical Depression Seventeen-E by the National Hurricane Center. Gradual strengthening lead to an increase in winds to 40 mph (65 km/h) and the depression was upgraded to Tropical Storm Narda at 18z on August 26. A mid-level eye formed on satellite imagery the next day, and soon after Narda became a hurricane. It peaked as an 85 mph (140 km/h) Category 1 hurricane with a minimum central pressure of 983 mbar (29.03 inHg) near the coast of Colima, Mexico. Colder sea surface temperatures began to affect the storm, leading to its slow and timely demise. Narda weakened to a tropical storm by 06z on August 29, and further to a tropical depression by 12z on August 30. Narda's circulation began to elongate, and the storm was no longer traceable by the next day.

Hurricane Octave

Category 2 hurricane (SSHWS)
Hilda 2021-07-31 2110Z.jpg Octave Track EPAC 2025 - CycloneMC.png
DurationSeptember 1 – September 7
Peak intensity100 mph (155 km/h) (1-min)  979 mbar (hPa)

The precursor to Hurricane Octave developed over Africa on August 18, exiting the coast a day later. The wave entered the Eastern Pacific on August 29, following behind Tropical Storm Narda as it continued to weaken. On September 1, the system was designated as Tropical Depression Eighteen-E as a closed low-level circulation developed and was easily detectable on satellite imagery. It gradually intensified over the coming days, becoming Tropical Storm Octave late on the same day it developed. Octave swiftly intensified into a Category 1 hurricane two days later, and peaked as a 100 mph (155 km/h) Category 2 hurricane 18 hours after initially becoming a hurricane. Its peak was quick as Octave began to slow and turn north while weakening. It weakened to a tropical storm on September 5, and became a post-tropical storm on September 7.

Tropical Storm Priscilla

Tropical storm (SSHWS)
Priscilla Sim EPAC 2025 - CycloneMC.jpg Priscilla Track EPAC 2025 - CycloneMC.png
DurationSeptember 2 – September 2
Peak intensity40 mph (65 km/h) (1-min)  1008 mbar (hPa)

A very weak and convection-anemic system developed quickly to the south of Guatemala. Much to the National Hurricane Center's surprise, the system rapidly developed into Potential Tropical Cyclone Nineteen-E very late on September 1 despite a lack of convection. The system was forecast to strengthen into a tropical storm as it made landfall in Guatemala. Less than two hours after its designation as a potential tropical cyclone, the system became Tropical Storm Priscilla on September 2. It's tropical storm peak only lasted six hours, as shear began to increase expeditiously, exposing Priscilla's center and nearly erasing any convection associated with the cyclone. Priscilla struggled on as a tropical depression for just another twelve hours, before degenerating into a remnant low off the coast of Guatemala. It's exposed circulation moved ashore and rapidly deteriorated on September 3.

Tropical Storm Raymond

Tropical storm (SSHWS)
Raymond Sim EPAC 2025 - CycloneMC.jpg Raymond Track EPAC 2025 - CycloneMC.png
DurationSeptember 5 – September 6
Peak intensity45 mph (75 km/h) (1-min)  1005 mbar (hPa)

A disturbed area of convective showers was located south of the Baja California Peninsula on September 2. It slowly organized until it became Tropical Depression Twenty-E on September 5. Moving north, the depression intensified and was named Raymond as it gained tropical storm-force winds. The system did not intensity much, as southerly shear and quick movement prevented significant strengthening. Raymond made landfall as a 45 mph (75 km/h) storm near Topolobampo, Sinoloa, Mexico. It rapidly weakened and moved inland, merging with another system across the southwest United States on September 6.

Tropical Storm Sonia

Tropical storm (SSHWS)
03E 2021-06-12 2155Z.jpg Sonia Track EPAC 2025 - CycloneMC.png
DurationSeptember 8 – September 10
Peak intensity40 mph (65 km/h) (1-min)  1005 mbar (hPa)

A tropical wave emerged off the coast of Africa on August 23. It entered the Eastern Pacific on September 4, becoming a tropical depression on September 8. Twenty-One-E strengthened into Tropical Storm Sonia twelve hours later as convection increased and satellite estimates supported tropical storm intensity. Although expected to strengthen into a near hurricane strength system, Sonia unexpectedly collapsed and struggled to reorganize. On September 10, Sonia was downgraded to a remnant low, and it's associated energy was absorbed into the intertropical convergence zone.

Hurricane Tico

Category 4 hurricane (SSHWS)
Tico Sim EPAC 2025 - CycloneMC.jpg Tico Track EPAC 2025 - CycloneMC.png
DurationSeptember 21 – September 27
Peak intensity155 mph (250 km/h) (1-min)  932 mbar (hPa)

The remnants of Hurricane Jerry made landfall in Nicaragua on September 19. Jerry's remnants merged with a disturbance the Eastern Pacific on September 20 and developed into Tropical Depression Twenty-Two-E on the 21th. Twelve hours later the system strengthened into a tropical storm, earning the name Tico. Tico rapidly developed an eye-feature in its mid-levels, but convective blowups shrowded the eye very quickly. It continued to gradually strengthen and another eye feature appeared on satellite and microwave imagery. Convection wrapped around the eye and Tico strengthened into a hurricane on September 22. The hurricane strengthened at a constant rate, becoming a major hurricane on September 23. Tico peaked as a Category 4 storm the next day, just under Category 5 intensity. Tico remained an intense hurricane until it made landfall as a strong Category 3 storm near Mazatlan, Sinaloa, Mexico late on September 26, becoming the fourth storm of the season to impact this area, and the strongest of them all to impact the area. The mountainous and rugged terrain of Mexico led to Tico's rapid deterioration and weakening. It became post-tropical on September 27, the remnants continuing over Texas and the southern United States and bringing more unpleasant weather along its path.

Tico is tied with a hurricane of the same name in 1983, Hurricane Olivia in 1967, Hurricane Lane in 2006, and Hurricane Odile in 2014 for the fourth strongest landfall on record in the Eastern Pacific with sustained winds of 125 mph (205 km/h). Damage associated with Hurricane Jerry's remnants/Hurricane Tico's precursor is relatively unrelated to the damage total of Tico. However its landfall near Mazatlan and associated impacts after landfall resulted in a total of $729 million in damages and 10 casualties.

Hurricane Velma

Category 3 hurricane (SSHWS)
Lane 2018-08-18 2015Z.jpg Velma Track EPAC 2025 - CycloneMC.png
DurationSeptember 26 – October 3
Peak intensity125 mph (205 km/h) (1-min)  947 mbar (hPa)

Tropical Depression Twenty-Three-E formed from a cluster of thunderstorms located in the open Pacific. Originally expected not to develop, the depression was anticipated to remain weak, strengthening into a tropical storm briefly before dissipating. Unfortunately, the system began a period of rapid intensification, becoming Tropical Storm Velma six hours later, and Hurricane Velma by September 27. The system continued to intensify into a major hurricane, topping out just below Category 4 intensity. Odd steering currents pushed Velma to the east, sustaining Category 3 hurricane intensity as it crawled east. Velma's slow movement eventually caught up to itself, leading to weakening and eventual stalling. Velma slowed to near stationary as it weakened to a tropical storm. The system moved north, and eventually northwest, and weakened to a tropical depression before dissipating on October 3.

Tropical Depression Twenty-Four-E

DurationOctober 1 – October 2
Peak intensity35 mph (55 km/h) (1-min)  1007 mbar (hPa)

A disorganized area of convection was situated south of the Baja California Peninsula on September 29. The system barely moved and hardly intensified due to cold waters in the wake of Hurricane Tico. As it slowly moved northwest, it developed into Tropical Depression Twenty-Four-E as it moved towards the Baja California Peninsula. As the depression moved onshore, ground observations supported tropical storm intensity, but the National Hurricane Center did not follow through with an upgrade. The system shortly lost all convection and its low level remnant continued northeast towards Mexico as it continued to elongate.

Tropical Storm Wallis

DurationOctober 14 – October 16
Peak intensity40 mph (65 km/h) (1-min)  1005 mbar (hPa)

A tropical wave lingered near the coast of Panama on October 10, and began moving deliberately to the west. It developed into a weak and disorganized tropical depression on October 14. The depression (Twenty-Five-E) intensified into a tropical storm twelve hours after formation, due to a convective blowup, and received the name Wallis. Wallis remained extremely disorganized and sheared, and it weakened back to a tropical depression just eighteen hours after becoming a tropical storm. A day later, Wallis became a remnant low. Wallis' remnant continued west until becoming unrecognizable on October 18.

Tropical Storm Xina

DurationOctober 18 – October 22
Peak intensity65 mph (100 km/h) (1-min)  998 mbar (hPa)

A tropical wave arrived at the Central American coast on October 14. It crossed into the Eastern Pacific on October 15 and slowly organized as it traversed northwest. On October 18, the sprawling system became Tropical Depression Twenty-Six-E as it swiftly moved towards the Mexican coastline. It became Tropical Storm Xina just before making a very brief and borderline landfall west of El Zapotalito in Oaxaca, Mexico as a 40 mph (65 km/h) tropical storm. Xina paralleled the coast and moved west, weakening once again to a tropical depression on October 19 under the influence of nearby Tropical Storm York. Xina quickly reorganized with the help of some land interaction and intensified as it began to move west-northwest. It peaked as a 65 mph (100 km/h) tropical storm before moving onshore in Colima, becoming the fifth storm to impact this area of the Mexican coastline this season. The system lost a majority of its convection, yet its close proximity to the Pacific Ocean helped it maintain tropical storm intensity for another few days. Mexico's mountainous terrain once again began to shred Tropical Storm Xina and it dissipated on October 22.

Overall impacts due to flooding rains and storm surge accumulated to $46 million in damages, and 4 casualties.

Hurricane York

Category 4 hurricane (SSHWS)
York Sim EPAC 2025 - CycloneMC.jpg York Track EPAC 2025 - CycloneMC.png
DurationOctober 19 – October 27
Peak intensity155 mph (250 km/h) (1-min)  925 mbar (hPa)

The precursor to York developed quickly to the east of Panama. Early on October 19, the system rapidly developed into a tropical depression, with the designation of Twenty-Seven-E. Twelve hours later the depression intensified into Tropical Storm York, and in similar fashion to other systems previously in the season it began a period of rapid intensification. York attained winds of 70 mph (110 km/h) before stalling at this intensity due to an unstable environment, partially influenced by Tropical Storm Xina to its northwest. York struggled to bring its eye out, but eventually intensified into a hurricane while this process was occurring. York's rapid intensification continued as it crawled northwest, and as Xina moved further inland, York continued to rapidly intensify. York intensified to a Category 2 on October 21, and continued to intensify into a Category 4 hurricane by the next day. York slowed down dramatically once again due to Xina's large swath and proximity. York attained its peak intensity of 155 mph (250 km/h) on October 23, just below Category 5 status. York weakened to a Category 3 storm as it began to move north and feel the effects of some upwelling due to its near stationary movement. This weakening phase bottomed out at 110 mph (a Category 2 hurricane), before swiftly restrengthening to a Category 4 storm and making landfall in a similar location to Xina five days prior. York made landfall with winds of 145 mph (230 km/h) before following Xina's path. York rapidly weakened to a tropical storm by October 26, and a tropical depression six hours later. York briefly moved back over water and intensified into a tropical storm before striking Mazatlan on October 27, dissipating shortly after. York's landfall in Mazatlan made it the sixth storm of the season to impact that area.

Damages from York worsened the effects from Tropical Storm Xina. Areas hit hard by Xina's flooding rains and storm surge did not have time to prepare for another storm, let alone a Category 4 hurricane. Damages were reported to be $923 million, with higher potential. Casualties were reported at a total of 186. York quickly became the fifth costliest hurricane in the Eastern Pacific, surpassing Hurricane Willa's record of $825 million. York is just behind Tropical Storm Agatha in 2010, which caused $1.1 billion.

Hurricane Zelda

Category 4 hurricane (SSHWS)
Douglas 2020-07-23 0120Z.png Zelda Track EPAC 2025 - CycloneMC.png
DurationOctober 23 – October 27
Peak intensity130 mph (215 km/h) (1-min)  948 mbar (hPa)

An area of low pressure developed towards the intertropical convergence zone on October 18. The system slowly moved to the west as it very gradually organized. On October 23, the system developed into Tropical Depression Twenty-Eight-E. Amidst a favorable environment, Twenty-Eight-E continued intensifying and became Tropical Storm Zelda late the same day. Zelda entered a period of quick intensification, becoming a hurricane by 12z October 24. Zelda peaked as a low-end Category 4 storm on October 25. Zelda's small size led to it entering a period of weakening, as increasing shear also began to take a toll on the system. Zelda weakened below hurricane status by 18z on October 26, and eventually to a remnant low the next day.

Tropical Storm Alpha

Tropical storm (SSHWS)
Jimena 2021-08-05 1945Z.jpg Alpha Track EPAC 2025 - CycloneMC.png
DurationOctober 23 – October 27
Peak intensity70 mph (110 km/h) (1-min)  987 mbar (hPa)

On October 17, an area of low pressure developed near the Gulf of Tehuantepec. This area of disheveled thunderstorms continued west very slowly, gaining a mid-level center and eventually a low-level center. Once this low-level center was found to be closed, advisories on Tropical Depression Twenty-Nine-E were initiated on October 23. Later that day, the system strengthened into a tropical storm, earning the Greek letter Alpha as a name. Alpha organized and intensified as it moved generally west, reaching a peak of 70 mph (110 km/h). At its peak, Alpha had an eye-like feature, which eventually deteriorated as it moved over colder waters by October 25. Alpha weakened to a tropical depression and executed a slow turn to the west-southwest, becoming a remnant low on October 27.

With the naming of Alpha on October 23, this marked the first time the Eastern Pacific has exhausted its naming list and had to use the Greek letters as an auxiliary list. Alpha's designation as a tropical storm also tied 1992 in terms of named storms, with a total of 27.

Tropical Storm Beta

Tropical storm (SSHWS)
Nora 2015-10-11 2020Z.jpg Beta Track EPAC 2025 - CycloneMC.png
DurationNovember 1 – November 7
Peak intensity40 mph (65 km/h) (1-min)  1008 mbar (hPa)

A low riding and unexpected area of low pressure formed in the intertropical convergence zone and quickly organized into Tropical Depression Thirty-E well southeast of Hawaii on November 1. Initially struggling to intensify, Thirty-E became a tropical storm just before crossing into the Central Pacific and was designated as Tropical Storm Beta on November 2. Beta was extremely unorganized and failed to strengthen beyond 40 mph (65 km/h) before weakening to a tropical depression just over thirteen hours after entering the Central Pacific. Beta suffered the impacts of shear and dry air, resulting in its continued weak phase as it treked through the Central Pacific. While situated south of Hawaii, Beta finally was able to reintensity into a tropical storm on November 5. This second wind as a tropical storm was short lived as well,, and Beta weakened to a tropical depression once again by 12z the next day. Beta brawled against dry air and shear but eventually lost all cyclonic characteristics on November 7. The weak and elongated remnants of Beta were absorbed by the ITCZ a day later.

Tropical Storm Gamma

Tropical storm (SSHWS)
18E 2021-11-06 1540Z.jpg Gamma Track EPAC 2025 - CycloneMC.png
DurationNovember 9 – November 11
Peak intensity45 mph (75 km/h) (1-min)  1007 mbar (hPa)

An area of disturbed weather developed into a small depression of November 9, earning the designation Tropical Depression Thirty-One-E. Its small size helped it intensity into Tropical Storm Gamma. Gamma was a short lived tropical cyclone, as convection began waning almost immediately after becoming a tropical storm. Short bursts of convection helped the system sustain tropical storm status for another day, eventually weakening to a tropical depression on November 11. A downburst within the system's core caused it to disrupt its own center, and Gamma's final advisory was issued as there was no longer a traceable center.

Hurricane Delta

Category 5 hurricane (SSHWS)
Willa 2018-10-21 2020Z with a pinhole.png Delta Track EPAC 2025 - CycloneMC.png
DurationNovember 20 – November 23
Peak intensity160 mph (260 km/h) (1-min)  918 mbar (hPa)

A quickly moving area of low pressure developed way to the south of Gulf of Tehuantepec on November 19. At 00z the next day, the system was designated as Tropical Depression Thirty-Two-E. An unusually favorable environment led to explosive intensification, and Thirty-Two-E became Tropical Storm Delta just as fast as it had formed. Delta's intensification was unprecedented, becoming a hurricane by 00z on November 21, a major six hours after that, and a Category 5 storm with a pinhole eye and extremely intense cloud tops another six hours later. Delta is the latest recorded Category 5 storm in the Eastern pacific, squandering the previous record held by Hurricane Kenna of 2002 by nearly a month. Delta peaked with winds of 160 mph (260 km/h) and a central pressure of 918 mbar (27.11 inHg), weakening quickly after peaking due to the small pinhole eye collapsing. Rapid weakening ensued after Delta peaked, its eye collapsing and convection waning as below-average and colder sea-surface temperatures took hold of the cyclone. Delta weakened to a Category 1 by 12z November 22, and a tropical storm six hours later. Delta continued to deteriorate and became a remnant low by November 23. Delta's remnant low continued across the basin with zero convection for several days, before being blasted by wind shear from a system near Hawaii (which would eventually become Tropical Storm Pena.).

Tropical Storm Pena

Wanda 2021-11-02 1548Z.jpg Pena Track CPAC 2025 - CycloneMC.png
DurationDecember 4 – December 10
Peak intensity50 mph (85 km/h) (1-min)  990 mbar (hPa)

A kona storm located northwest of Hawaii slowly began to gain subtropical characteristics after executing a cyclonic loop on December 1st and 2nd. The low eventually moved south into a more favorable region for development, becoming Subtropical Storm Pena according to the Central Pacific Hurricane Center on December 4. The cyclone developed an eye-like feature at this point, but ASCAT and buoy observations confirmed that Pena had not strengthened past the 45 mph (75 km/h) threshold. Pena transitioned into a tropical storm and strengthened to 50 mph (85 km/h) before convection waned. Pena executed an anti-cyclonic loop and moved south, beginning a period of erratic movement and fluctuations in intensity as the storm attempted to reconsolidate after its peak. Pena began to advance to the north very quickly under the influence of yet another non-tropical low to its northwest. Pena sped away over the Leeward Hawaiian Islands and became post-tropical on December 10.

Retirement

On On March 12, 2025, at the 48th session of the RA IV hurricane committee, the World Meteorological Organization retired the names Mario, Tico, and York due to their devastating and catastrophic impacts on the Mexican coast, and they will not be used again for another Pacific hurricane. They were replaced with Miguel, Tonio, and Yates for the 2031 Pacific hurricane season. With three names retired, 2025 held the record for most names retired in a single Pacific hurricane season, with all previous retired names from previous seasons in singularity.

Season Effects
