San Francisco woke up to a noticeably milder start today with temperatures in the mid-50s and mostly clear skies. Inland neighborhoods are set for the biggest afternoon warmup, while the immediate coast hangs back on the cooler side. Expect a light west-southwest breeze later in the day and lows dipping into the low 50s overnight.
Afternoon Highs And Where They'll Be Hottest
Inland pockets and the East Bay valleys are poised to be the warm spots, with highs climbing into the upper 70s to low 80s this afternoon, while the waterfront holds in the 60s to low 70s, according to the National Weather Service. Temperatures should slide back into the low 50s overnight as the marine influence reasserts itself.
Fog, Wind And Evening Cooling
A shallow marine layer could linger near the shore or reform after sunset, bringing pockets of fog to Ocean Beach, the Marina and other low-lying spots. West-southwest winds will stay light to moderate this afternoon (about 3–9 mph) and may gust a bit higher on exposed hilltops and bridge approaches, just enough to remind you this is still San Francisco.
Boaters And Interior Fire Weather
Offshore, small craft conditions are possible, and on land, the forecast discussion flags elevated fire-weather concerns for parts of the interior Bay Area and the Central Coast, a result of warm, dry air and breezy offshore flow, the NWS forecast discussion notes. Boaters should expect choppy seas from Point Arena to Point Reyes and check local marine advisories before heading out, while people working outdoors inland should take standard heat-and-fire precautions (stay hydrated, keep ignition sources away from dry grass, and have a plan to cool down).
For most San Franciscans, the takeaway is straightforward: pack a layer if you are heading to the water, grab a bottle of water for outdoor plans inland, and check forecasts and marine advisories before you go, since updates are expected if conditions shift.
