The 2022 Pacific hurricane season was a fairly active tropical cyclone season, with 19 named storm altogether. Ten of those became hurricanes, and four further intensified into major hurricanes (category 3 or higher on the 5-level Saffir–Simpson wind speed scale). Two of this season's storms, Bonnie and Julia, survived the overland crossover from the Atlantic. The season officially started on May 15 in the eastern Pacific—east of 140°W—and June 1 in the central Pacific—between the International Date Line and 140°W, and ended in both regions on November 30. These dates conventionally delimit the period of each year when most tropical cyclones form in the eastern Pacific basin. The season's first storm, Agatha, formed on May 28, and last, Roslyn, dissipated on October 23. Roslyn made landfall in Nayarit with winds, making it the strongest landfalling Pacific hurricane since Patricia in 2015. The season's first major hurricane, Bonnie, entered into the basin from the Atlantic basin on July 2, after crossing Nicaragua as a tropical storm, becoming the first storm to survive the crossover from the Atlantic to the Pacific since Otto in 2016. Three months later, Julia became the second to do so.

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.

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__
