San Francisco is starting Monday with clear skies and temperatures around 53 degrees, but the calm city forecast comes with a serious shoreline warning. The day should stay sunny with a high near 66, while Monday night drops to about 52.
The National Weather Service says dangerous beach conditions will continue through Monday evening, with strong rip currents, sneaker waves, and isolated breaking waves of 18 to 20 feet possible at favored break points. A Coastal Flood Advisory remains in effect through Tuesday afternoon for low-lying areas near San Francisco shorelines and tidal waterways.
High Tide Could Push Water Into Low-Lying Areas
Monday's high tide is expected around 12:46 p.m., reaching roughly 7.3 feet on the San Francisco gauge and running about 1.5 feet above normal. Flooding could affect coastal trails, parks, lots, and some roads, with isolated closures possible.
Anyone heading toward the coast should stay off jetties, piers, rocks, and other waterside infrastructure. The forecast calls for waves and currents strong enough to sweep people into the water, so officials are urging visitors to remain out of the surf and never turn their backs on the ocean.
Cool Start Gives Way To A Warm Late Week
Tuesday brings overcast skies west of Twin Peaks and only fleeting sunshine downtown, with coastal temperatures in the 60s and afternoon gusts up to 20 mph. Wednesday stays sunny and reaches about 72 degrees, keeping the middle of the week comfortable by San Francisco standards.
The bigger change arrives Thursday, when temperatures are expected to climb to around 82 degrees. Friday and Saturday should bring temperatures within a broad coastal range.
Clear Skies And No Rain In The City Forecast
No rain is expected in San Francisco through Sunday, and skies should remain mostly clear overnight. Monday afternoon winds increase from the west to around 12 mph, while the National Weather Service says warmer, drier conditions later in the week could bring elevated fire-weather concerns, particularly outside the city.
