Super El Niño Threatens Record Wet Winter in California
US · Published Oct 21, 2026
• California is facing an unusually high risk of a record-wet winter due to the combined effects of climate change and a super El Niño.
• Coastal waters are warming significantly, with sea surface temperatures 3.6–10.8°F above average, contributing to rising sea levels and increased moisture in incoming storms.

Impact & Risks

The potential for catastrophic flooding poses significant risks to infrastructure, homes, and vulnerable populations, particularly in low-lying coastal areas. Coastal flooding during king tides could lead to widespread damage, while heavy rainfall may strain emergency response systems. Non-Hispanic Black and under-resourced communities face disproportionate risks, with property damage and displacement likely in flood-prone areas.
