The 2025 Atlantic hurricane season was one of the most active Atlantic hurricane seasons on record, reaching 20 named storms, tying 2021 and 1933 for the second-most active season on record. The season began on June 1, 2025, and ended on November 30, 2025; however, storms can form outside of these boundaries, as Tropical Storm Van did in late December. The season featured the earliest major hurricane since Hurricane Claudette in June 2021.

Ahead of and during the season, several national meteorological services and scientific agencies forecast how many named storms, hurricanes, and major hurricanes (Category 3 or higher on the Saffir–Simpson scale) will form during a season and/or how many tropical cyclones will affect a particular country. These agencies include the Tropical Storm Risk (TSR) Consortium of University College London, the National Oceanic and Atmospheric Administration (NOAA) and Colorado State University (CSU). The forecasts include weekly and monthly changes in significant factors that help determine the number of tropical storms, hurricanes, and major hurricanes within a particular year. Some of these forecasts also take into consideration what happened in previous seasons and the state of the El Niño–Southern Oscillation (ENSO). On average, an Atlantic hurricane season between 1981 and 2010 contained twelve tropical storms, six hurricanes, and three major hurricanes, with an accumulated cyclone energy (ACE) index of between 66 and 103 units.
The first forecast for the year was released by TSR on December 11, 2024, which predicted a near average season in 2025, with a total of 12 named storms, 5 hurricanes, and 3 major hurricanes, due to the anticipated presence of El Niño conditions during the season. On April 4, 2025, CSU released its forecast, predicting a near-average season of 13 named storms, 5 hurricanes and 2 major hurricanes. On April 16, TSR released an updated forecast that revised its earlier predictions, expecting 12 named storms, 6 hurricanes, and 3 major hurricanes. North Carolina State University released their forecast on May 6, predicting slightly-above average activity with 13–16 named storms, 5–7 hurricanes and 2–3 major hurricanes. On May 21, the Weather Company predicted an above average season, with 15 named storms, 8 hurricanes, and 4 major hurricanes. The UK Met Office released their forecast May 23, predicting 13 named storms, 7 hurricanes, 3 major hurricanes and an accumulated cyclone energy of 109 units. On May 23, NOAA released their first prediction, calling for a near-normal season with 9–15 named systems, 4–8 hurricanes, and 2–4 major hurricanes. On May 30, NOAA released a forecast, which called for an above average season with 14–16 named storms, 6–8 hurricanes, and 2–4 major hurricanes.
Mid-season outlooks[]
On June 11, CSU updated their forecast to include a total of 14 named storms, 7 hurricanes and 4 major hurricanes. On June 4, the TSR released their first mid-season outlook, adding two more named storms. On July 4, University of Arizona (UA) predicted above-average activities: 16 named storms, 8 hurricanes, 4 major hurricanes, and accumulated cyclone energy index of 175 units. On August 5, the CSU released their third mid-season outlook, still retaining the same numbers from their previous forecast except the slight increase of the number of named storms. On August 6, the TSR released their second and final mid-season outlook, with the only changes of increasing the number of named storms from 12 to 13. On August 8, NOAA released their second prediction with increasing the chances for 16–18 named storms, 8–10 hurricanes, and 3–5 major hurricanes, suggesting very above-average activity.
The interaction of an upper-level trough and a stalled front over the Florida Straits led to the formation of a low-pressure area in that region on June 12, moving northeast into the subtropical Atlantic. The National Hurricane Center (NHC) first noted this system on their tropical weather outlook (TWO) graphic on June 12, giving it a 30% chance of development within the next 48 hours; however, this was abruptly changed to 70% the next morning, as the cyclone began to develop subtropical characteristics, leaving some of its extratropical traits behind. Invest 91L was designated at this time (Invest 90L was an area of interest in the Gulf of Mexico earlier in the month). On the morning of June 14, the National Hurricane Center upped the chances on Invest 91L to 90%, and subsequently designated the invest as Subtropical Depression One at 03:00 UTC that morning. Continuing northeast, the system transitioned into a tropical cyclone, and gained gale-force winds shortly after, at 06:00 UTC. At 12:00 UTC on June 14, Tropical Storm Andrea was designated, becoming the first storm of the 2025 season. Strengthening had halted for the rest of the day on June 14. On the morning of June 15, Andrea gained winds of 40 kt (45 mph), with a pressure of 1003 millibars, and six hours later, at 06:00 UTC, Andrea reached its peak intensity, with winds remaining the same, but the barometric pressure dropping to 1002 millibars. Andrea prompted tropical storm warnings for Nova Scotia that morning. Andrea ended up making its first landfall southwest of Liverpool at 19:00 UTC on June 15, and a second landfall south of Liverpool at 19:45 UTC, with winds of 40 mph. Land interaction caused Andrea to eventually weaken in to a tropical depression at 00:00 UTC on June 16, which led to Andrea transitioning into a remnant low at 03:00 UTC that day.
The following list of names was used for named storms that formed in the North Atlantic in 2025. The names not retired from this list will be used again in the 2031 season. This was the same list used in the 2019 season, with the exception of the names Darren and Lucas, which replaced Dorian and Lorenzo.

Retirement[]
The World Meteorological Organization (WMO) retired the names Humberto, Imelda, Melissa, Nestor, Olga, and Sebastien from its rotating naming lists due to the number of deaths and amount of damage they caused, and they will not be used again for another Atlantic hurricane. They will be replaced with Heath, Ivy, Mandy, Noah, Odessa, and Steve, respectively, for the 2031 season. This was the highest names ever retired in one season on record in the North Atlantic basin.
