The 2023 Pacific hurricane season was an active and highly destructive Pacific hurricane season which went on to become the costliest on record, primarily due to Hurricane Otis. In the Eastern Pacific basin, 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, no tropical cyclones formed for the fourth consecutive season, though four entered into the basin from the east. Collectively, the season had an above-normal accumulated cyclone energy (ACE) value of approximately 168 units. This season saw the return of El Niño and its associated warmer sea surface temperatures in the basin, which fueled the rapid intensification of several powerful storms. It officially began on May 15, 2023 in the Eastern Pacific, and on June 1 in the Central; both ended on November 30. These dates, adopted by convention, historically describe the period in each year when most tropical cyclogenesis occurs in these regions of the Pacific. 17 storms, 10 hurricanes, 8 major hurricanes (Category 3+). Strongest: Otis (165 mph). Accumulated cyclone energy ≈ 168. Wiki link
