San Francisco started today under cool, mostly clear skies, with temperatures hovering near 52°F. Sunshine is expected to nudge inland highs into the mid-70s, but the real story over the next 24 to 36 hours is the wind. Gusty conditions will hammer higher ridgelines and mountain passes, and already hazardous surf along the coast will stay risky.
Afternoon Winds Pick Up
Light west-northwest breezes this morning are forecast to build to 3 to 15 mph by afternoon, with urban gusts climbing into the 20s. Winds are expected to strengthen through the evening, with gusts rising into the 30s Sunday night and even higher on exposed ridges.
Where To Be Careful
A Wind Advisory is in effect for the Santa Cruz Mountains, North Bay interior mountains, the East Bay hills, and parts of the Santa Clara foothills from 11 PM today through 11 AM tomorrow. North-northeast gusts are expected to reach 50 mph, with local peaks up to 60 mph. The National Weather Service office in San Francisco also has a Beach Hazards Statement in effect through Monday morning, warning of very rough surf, strong rip currents, and dangerous longshore currents. The agency is urging people to stay off jetties, piers, rocks, and other waterside infrastructure. According to NWS San Francisco, these conditions can quickly sweep people into cold, turbulent water or cause local erosion of shoreline trails.
Marine, Commute And Fire Concerns
Gale and storm warnings will keep seas rough through the weekend, with offshore waves building to about 19 feet at the peak. That will make boating hazardous and can reduce visibility near shore because of sea spray. Strong gusts will also make bridge crossings and exposed roadways tricky for high-profile vehicles, and the combination of dry fuels and gusty winds brings elevated fire weather concerns for interior slopes through Monday. Secure patio furniture, delay anything that could produce sparks, and be prepared for isolated power interruptions in the highest wind spots.
Quick Safety Tips
If you had beach or tide-pool plans, postpone them until conditions calm, and stay well back from the surf line; never turn your back on the ocean. Keep loose outdoor items tied down, avoid driving near exposed shorelines when gusts peak, and check updates from NWS and local marine advisories before heading out.
