San Francisco, CA — California's coastline is facing a dangerous combination of towering waves, rising tides and heavy surf as a powerful Pacific weather pattern continues. Breaking waves reaching 20 to 25 feet, with occasional sets approaching 35 feet, threaten beaches from San Francisco to Monterey.
The immediate concern extends beyond rough water. Coastal flooding, isolated road closures and dangerous shoreline conditions could affect residents and visitors through early Tuesday.
According to the National Weather Service San Francisco Bay Area office, a High Surf Advisory remains in effect until 4 a.m. Tuesday, November 17.

35 Foot Waves Threaten California Beaches The National Weather Service warns that breaking waves of 20 to 25 feet will continue along Pacific Coast beaches.
Occasional wave sets could reach 25 to 35 feet at favored coastal locations.
Affected areas include San Francisco, coastal Marin County, the San Francisco Peninsula, Monterey Bay and Big Sur.
High tides may flood low lying infrastructure, while powerful waves could accelerate coastal erosion.
