Through El Niño–Southern Oscillation and Atmospheric pressure

The first named storm of the season, Hurricane Agatha, formed on May 28, and made landfall two days later at Category 2 strength on the Saffir–Simpson scale, making it the strongest hurricane on record to make landfall during the month of May in the Eastern Pacific basin. In June, Hurricane Blas and Tropical Storm Celia caused heavy rainfall over southwestern Mexico despite remaining offshore. The season's first major hurricane, Hurricane Bonnie, moved offshore Nicaragua as a tropical storm on July 2, becoming the first storm to survive the crossover from the Atlantic to the Pacific intact since Hurricane Otto in 2016. In September, tropical storms Javier, Lester, and Madeline all caused flooding across the Pacific coast of Mexico, though none left severe damage. Hurricane Kay also formed that month, and struck the Baja California Peninsula before bringing gale-force winds to the west coast of the continental United States, becoming the first Pacific hurricane to do so since Hurricane Nora 25 years earlier.

In early October, Hurricane Orlene became a Category 4 hurricane before weakening and making landfall in Sinaloa as a Category 1 hurricane, resulting in heavy rainfall and flooding. Also, Hurricane Julia became the second storm of the season to cross over from the Atlantic basin intact, and made landfall in El Salvador soon thereafter. In late October, Hurricane Roslyn became the fourth major hurricane of the season, and went on to become the strongest landfalling Pacific hurricane since Hurricane Patricia in 2015.

Seasonal forecasts

Forecasts include weekly and monthly changes in important factors that help determine the number of tropical storms, hurricanes, and major hurricanes within a particular year. According to the National Oceanic and Atmospheric Administration (NOAA), the average hurricane season in the Eastern and Central Pacific between 1991 and 2020 contained approximately 15 tropical storms, 8 hurricanes, and 4 major hurricanes. The NOAA generally classifies a season as above average, average, or below average based on the cumulative ACE index, but occasionally the number of tropical storms, hurricanes, and major hurricanes within a hurricane season is also considered. Factors they expected to reduce activity were near- or below-average sea surface temperatures across the eastern Pacific and the El Niño–Southern Oscillation remaining in the neutral phase, with the possibility of a La Niña developing, corresponding to a low chance of an El Niño.

On May 17, 2022, the Servicio Meteorológico Nacional (SMN) issued its forecast for the season, predicting a total of 14–19 named storms, 6–9 hurricanes, and 2–4 major hurricanes to develop. On May 24, 2022, the National Oceanic and Atmospheric Administration (NOAA) issued their outlook, calling for a below-normal season with 10–17 named storms, 4–8 hurricanes, 0–3 major hurricanes, and an accumulated cyclone energy index of 45% to 100% of the median.
