The 2021 Pacific hurricane season is an ongoing event in the annual tropical cyclone season in the North Pacific Ocean. It officially began on May 15 for the Eastern Pacific and on June 1 for the Central Pacific. Both seasons will end on November 30, though storms often develop outside the season boundaries. These dates, adopted by convention, historically describe the period in each year when most Eastern Pacific tropical systems form.[1] However, storm formation is possible at any time of the year, as illustrated in 2021 by the formation of the season's first named storm, Tropical Storm Andres, on May 9.
This timeline documents tropical cyclone formations, strengthening, weakening, landfalls, extratropical transitions, 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, such as a storm that was not initially warned upon, has been included.
