El Niño Threatens California With Coastal Flooding
El Niño Threatens California With Coastal Flooding
US · Published Sep 22, 2026
A strengthening El Niño is expected to bring significant impacts to California's coastline, including higher sea levels, powerful waves, and increased risks of beach erosion and coastal flooding.
According to NOAA, El Niño occurs when warm Pacific waters shift eastward due to weakened trade winds, altering weather patterns globally.

Impact & Risks

The coastal regions of California, including Monterey County, face heightened risks of flooding, erosion, and infrastructure damage due to elevated sea levels and stronger wave activity. Southern California beaches have already experienced significant erosion, with some areas losing up to 3.6 feet of coastline annually. The increased precipitation expected during the winter months could lead to flooding, debris flows, and mudslides, particularly in areas recently affected by wildfires. Residents in flood-prone areas or near vulnerable coastlines are advised to prepare for potential evacuations and property damage. The impacts of this El Niño could rival or exceed those of the 2015-2016 Super El Niño, which caused widespread disruption.
