The 2020 Pacific hurricane season was a near average Pacific hurricane season in terms of named storms, featuring 17 (including one unnamed tropical storm which was operationally classified as a tropical depression), but well below average season for hurricanes and major hurricanes, with only 4 hurricanes and 3 major hurricanes forming. Additionally, no tropical cyclones formed in the Central Pacific basin for the first time since 2017. The season officially began on May 15 in the East Pacific Ocean (east of 140°W), and on June 1 in the Central Pacific (from 140°W to the International Date Line, north of the equator; they both ended on November 30. These dates conventionally delimit the period of each year when most tropical cyclones form in the respective regions. However, the formation of tropical cyclones is possible at any time of the year, as illustrated in 2020 by the formation of the season's first system, Tropical Depression One-E, on April 25. This was the earliest formation of a tropical cyclone on record in the eastern Pacific basin proper. The final system of the season was Tropical Storm Polo, which dissipated on November 19.
The most significant storms of the season were Tropical Storm Amanda and Hurricane Genevieve. Amanda developed near Central America in late May and struck Guatemala, causing widespread damage in neighboring El Salvador and killing 40 people amid the COVID-19 pandemic in the latter country. Genevieve passed closely to the tip of the Baja California Peninsula in August, bringing hurricane-force winds and heavy rainfall, killing six and causing an estimated $50 million in damage. Otherwise, impact from other storms was minimal. In late July, Hurricane Douglas made an extremely close pass to Hawaii, with its weak southern eyewall crossing Oahu, causing minor effects. The remnant moisture of Tropical Storm Fausto brought dry thunderstorms and lightning to Northern California, sparking hundreds of fires that contributed to the state's worst fire season in recorded history, and the remnants of Genevieve dropped heavy rainfall in Arizona and Southern California. Tropical Storm Hernan moved very near the coast of southwestern Mexico, causing an additional fatality and several millions of dollars worth of damage. Collectively, the tropical cyclones of this season caused about US$267.91 million in damage and 47 deaths.
