San Francisco and Marin Face Record Summer Tides, Coastal Flooding Expected
US · Published Jun 16, 2026
San Francisco and Marin County are experiencing record-breaking summer tides, with water levels peaking at 2 feet above normal, according to the National Weather Service (NWS).
The highest summer tides on record were observed over the weekend, with additional peaks expected through Thursday.

Why It's Important?

The record tides are causing localized flooding in low-lying areas, disrupting pedestrian and vehicle traffic. In Marin County, neighborhoods like Golden Hind Passage have reported water entering garages and streets. San Francisco's Embarcadero has also experienced flooding, affecting cyclists and pedestrians. The NWS warns of potential road and parking lot closures, particularly along the Marin County shoreline and coastal Sonoma County. Hazardous beach conditions, including rip currents, pose additional risks to beachgoers. Long-term, rising sea levels could exacerbate these issues, with projections of up to 6 feet of sea level rise by the end of the century.
