The 2026 Pacific hurricane season is the current iteration of the annual cycle of tropical cyclone formation over the Pacific Ocean north of the equator and east of the International Date Line (IDL). The season officially began on May 15 in the Eastern Pacific basin proper (east of 140°W) and June 1 in the Central Pacific basin (140°W to the IDL), and will end on November 30 in both areas. This is historically the period during which most tropical cyclogenesis occurs in these respective areas. Activity during the season began on June 2 with the formation of Tropical Storm Amanda.
This timeline documents tropical cyclone formations, strengthening, weakening, landfalls, and dissipations during the season. It includes information that was not released throughout the season, meaning that data from post-storm reviews by the National Hurricane Center has been included.
The time stamp for each event is first stated using Coordinated Universal Time (UTC), the 24-hour clock where 00:00 = midnight UTC. The NHC uses both UTC and the time zone where the center of the tropical cyclone is currently located. The time zones utilized (east to west) are: Central, Mountain, Pacific and Hawaii. In this timeline, the respective area time is included in parentheses. Additionally, figures for maximum sustained winds and position estimates are rounded to the nearest 5 units (miles, or kilometers), following National Hurricane Center practice. Direct wind observations are rounded to the nearest whole number. Atmospheric pressures are listed to the nearest millibar and nearest hundredth of an inch of mercury. __TOC__
