California Coasts Under Coastal Flood Alerts Amid High Tides

Coastal flood warnings and advisories are active for California's coastlines, including San Diego and San Francisco Bay, through October 29, 2026. Astronomical high tides combined with elevated water levels are expected to cause minor to moderate seawater flooding in vulnerable areas like beach parking lots and walkways. Moderate to significant beach erosion is also anticipated, with a slight risk of isolated structural damage.
