It is a cool and foggy day in San Francisco, about 58°F with humidity close to the saturation point, but the real action is out at the ocean. A Beach Hazards Statement is in effect through Wednesday afternoon, warning of sneaker waves, strong rip currents, and large breaking surf on south- and southwest-facing beaches. Inland neighborhoods are expected to shake off the gloom with mostly sunny skies and highs near 70°F by the afternoon, while onshore winds pick up into the evening commute.

Afternoon Winds And Beach Hazards

A long-period southerly swell rolling in from the eastern Pacific is set to deliver wave sets that can break as high as 10 feet at some beaches and trigger sneaker waves that surge far up the sand. According to the National Weather Service, the Beach Hazards Statement runs through Wednesday afternoon, and multiple marine advisories, including Small Craft Advisories and a Gale Warning for portions of the outer waters, are posted for Bay Area coastal waters. Expect west winds generally in the 7 to 16 mph range this afternoon, with gusts climbing into the mid 20s, while exposed gaps and bluffs could see brief gusts into the 30s. That combo will leave the ocean choppy and turn some coastal walks into sand-in-your-face territory.

Plan Ahead

Officials urge beachgoers to favor lifeguarded spots, stay well clear of jetties and piers, and never turn their backs on the ocean, even when the surf looks deceptively calm. Boaters and small-craft operators should follow posted advisories and consider delaying launches if conditions look rough. Temperatures will slip back into the upper 50s after sunset, so anyone with evening plans near the water should bring a wind layer and check updated local forecasts before heading out.
