The 2025 Pacific hurricane season was notably active, becoming the first to produce 20 named storms since 2018, largely fueled by warmer-than-average sea surface temperatures off Mexico's western coast. In the Eastern Pacific basin, 18 named storms formed—including 11 hurricanes and 4 major hurricanes—while the Central Pacific saw 2 named storms, one of which reached major hurricane status, contributing to an above-normal accumulated cyclone energy (ACE) of about 127.3 units. The season ran from May 15 to November 30, and unlike the previous year's late start, it featured several early systems, including Tropical Storm Alvin (May 28) and Hurricane Erick, which became the earliest major hurricane to make landfall on either Mexican coast, causing at least US$350 million in damage and 24 fatalities. Other impactful storms included Tropical Storm Dalila, which triggered significant flooding in Mexico, and a series of September storms (Lorena, Mario, Narda) that brought similar effects. In October, remnant moisture from Hurricane Priscilla and Tropical Storm Raymond fueled floods and landslides in Mexico and heavy rain in the U.S. Southwest, before the final storm, Tropical Storm Sonia, dissipated on October 28. Forecasts varied, with Mexico's SMN predicting an above-average season (16–20 named storms) while NOAA initially called for a near-average one (12–18 named storms).
