San Francisco’s shoreline has two different hazards this weekend: high tides may affect low-lying bayfront areas, while powerful surf threatens exposed Pacific beaches. The National Weather Service Coastal Flood Advisory for San Francisco was in effect until 4 p.m. PST Friday, November 6. High-tide flooding concerns continue: Saturday’s San Francisco high tide is about 9:38 a.m., roughly 1.6 feet above normal, with possible flooding in low areas near shorelines and tidal waterways and isolated road closures possible through Nov. 13. Drivers should allow extra time, obey barricades and avoid driving through water of unknown depth.
For the Pacific coast, Hoodline’s report on the weekend NWS Beach Hazards Statement describes 12-to-16-foot breaking waves, sneaker waves and strong rip currents at exposed beaches through Monday evening. The report advises staying out of the water and away from jetties, piers and rocks. Check the NWS San Francisco Bay Area office for current alerts; bayfront flooding and Pacific surf hazards are distinct warnings.
Ocean Beach’s infrastructure problems extend beyond this weekend
The surf warning is temporary, but erosion has already affected infrastructure at Ocean Beach. The San Francisco Public Utilities Commission reports that erosion south of Sloat Boulevard undermined and damaged beach parking lots, stormwater drainage facilities and the Great Highway. Its Ocean Beach Climate Change Adaptation Project includes a planned buried seawall to protect a pump station, recycled water facility, wastewater treatment plant and other key infrastructure.
That longer-term erosion work is separate from the bayfront flood advisory. San Francisco Planning says high tides drenched Embarcadero roadways in January 2026, affecting travel and access. The agency’s Shoreline Adaptation Plan process is scheduled to run from 2026 to 2028 and guide preparation for sea-level rise and related coastal flooding, according to San Francisco Planning. Those documented impacts and planning efforts provide context for shoreline vulnerability; they do not establish a trend from this weekend’s forecast or explain its specific conditions.
