Most Destructive Pacific Hurricane Season | 2023 Eastern Pacific Hurricane Season Summary

The 2023 Pacific hurricane season was an active and destructive Pacific hurricane season. In the eastern Pacific basin (east of 140°W), 17 named storms formed; 10 of those became hurricanes, of which 8 strengthened into major hurricanes – double the seasonal average. In the central Pacific basin (between 140°W and the International Date Line), no tropical cyclones formed (for the fourth consecutive season), though four entered into the basin from the east. Collectively, the systems this season racked up an above-normal accumulated cyclone energy (ACE) rating of approximately 164 units. This season saw the return of El Niño and its associated warmer sea surface temperatures in the central and eastern tropical Pacific Ocean, which fueled the rapid intensification of several powerful storms

Forecasts at the outset of the 2023 season predicted busier-than-normal tropical cyclone activity in the eastern Pacific basin, largely due to El Niño. The season got off to a slow start, however, as there was no activity for the first six weeks of the season, making this one of the latest-starting seasons on record. When the first system, Hurricane Adrian, developed on June 27, it became the second-latest forming first named storm in the eastern Pacific in the satellite era (since 1971), behind only Tropical Storm Agatha in 2016. In July, Hurricane Calvin became the season's first major hurricane and passed just south of the Big Island of Hawaii as a tropical storm, bringing widespread rainfall to the area and neighboring Maui. In August, Category 4 Hurricane Dora passed south of the Hawaiian Islands and contributed to strong gradient winds over Hawaii, which in turn fanned the flames of multiple devastating wildfires. Later that month, Hurricane Hilary made landfall as a tropical storm in Baja California, then brought torrential rainfall and gusty winds to the Southwestern United States. In early September, Hurricane Jova, the first Category 5 hurricane in the basin since 2018, caused rainfall, high waves and rip currents in areas previously affected by Hilary.

October saw four tropical cyclones strike the Pacific Coast of Mexico. Tropical Storm Max struck Guerrero on October 9, resulting in intense flooding. Less than two days later, Hurricane Lidia rapidly intensified into a Category 4 hurricane and made landfall at peak intensity on Jalisco, Lidia was followed by Hurricane Norma, which made two landfalls in northwestern Mexico less than two weeks later. Hurricane Otis developed in the time period between Norma's landfalls, rapidly intensified into the second Category 5 hurricane of the season, and devastated Acapulco when it became the first Pacific hurricane to make landfall at Category 5 intensity, therefore surpassing Hurricane Patricia as the strongest landfalling Pacific hurricane on record
