The 2024 Pacific Hurricane season was well below average, with only 9 named storms, 3 hurricanes, and 1 major hurricane. The primary contributor to the below-average activity was a very strong La Niña. The season saw Hurricane Daniel narrowly miss a major hurricane landfall in Cabo San Lucas in early July. 2024 was also the last year in which the Central Pacific was considered a sub-basin of the Eastern Pacific, and the final year of operation for the Central Pacific Hurricane Center.
Seasonal Predictions[]
Every year, in preparation for the upcoming hurricane season, several seasonal forecasts and outlooks are issued by universities and national meteorological services. In 2024, CSU and UA began issuing forecasts and NOAA began issuing a mid-season forecast for the first time.

Pre-season forecasts[]
On April 5, 2024, Colorado State University released their forecast, calling for 14 named storms, 7 hurricanes, 3 major hurricanes, and an ACE index of 80 units. CSU cited the expected development of a Strong La Niña as the primary reason for the forecasted low activity. On April 19, 2024, the University of Arizona released their first forecast for the season, calling for 13 named storms, 6 hurricanes, 3 major hurricanes, and an ACE index of 80 units, citing the developing La Niña as the main source of their forecast. On May 1, 2024, NOAA released their forecast, calling for 10-16 named storms, 4-8 hurricanes, 2-4 major hurricanes, and an ACE index of 85 units. There was an expected 50% chance for below-average activity, 40% chance for near-average activity, and a 10% chance for above-average activity. NOAA cited similar reasons to CSU and UA for their forecast. On May 15, 2024, SMN released their forecast, predicting 13-19 named storms, 5-9 hurricanes, and 3-4 major hurricanes, citing similar reasons to other forecast agencies.
Mid-season forecasts[]
To avoid confusion, several forecasting agencies agreed upon July 20 through August 20 being the mid-season forecasting period. This year, UA, NOAA, and CSU issued mid-season forecast updates. On August 1, UA updated their forecast, calling for 12 named storms, 5 hurricanes, 2 major hurricanes, and an ACE index of 50 units. On August 5, NOAA updated their forecast, calling for 8-4 named storms, 4-8 hurricanes, 1-3 major hurricanes, and an ACE index of 55 units. On August 6, 2024, CSU updated their forecast, calling for 13 named storms, 6 hurricanes, 2 major hurricanes, and an ACE index of 55 units.
