High surf warning in effect for San Francisco until early Sunday

The National Weather Service has issued a High Surf Warning for San Francisco and nearby coastal areas, effective from 6 PM Friday until 4 AM Sunday, according to NWS San Francisco.

This warning includes dangerously large breaking waves estimated between 25 and 30 feet, with strong rip currents and sneaker waves also expected. Waves of this size can pose significant risks to swimmers and beachgoers.

In addition, a Coastal Flood Advisory is in effect until 4 PM Friday, with potential flooding of up to 1.5 feet in low-lying areas near shorelines and tidal waterways. High tides will push water and waves farther up the beach than usual, which may restrict escape routes from coastal areas.

The NWS advises caution near beaches, jetties, and rocks, as waves can sweep across the shoreline without warning, pulling people into the sea and increasing the risk of injury or drowning. Isolated road closures and coastal erosion are also possible due to the high tides and surf conditions.
