San Francisco is teeing up a classic spring stunner today, with sunshine and highs near 74°F following a cool, partly cloudy night. Inland neighborhoods will soak up the warmest readings, while the waterfront hangs a few degrees cooler under a thinner marine layer.
Afternoon Heat: Where It Hits Hardest
This afternoon highs should land around 74°F across the city, with many inland spots climbing into the low to mid 70s before a modest sea breeze trims a few degrees later in the day. Winds will stay on the lighter side, generally 3 to 8 mph from the north-northwest, so exposed hilltops will feel noticeably breezier than tucked-away blocks and backyards.
North Bay Winds And Marine Advisories
Offshore flow will kick up pockets of strong wind in the North Bay interior, where mountain-wave gusts could reach near 45 mph on higher peaks before dawn Friday, March 27. Small craft advisories and gale warnings remain posted for parts of the outer waters through today, and mariners are urged to follow the latest forecast discussion from the NWS.
Weekend Warmth And Next Week's Rain
The weekend keeps things pleasant and still running above normal, with most areas in the low to mid 70s on Saturday and Sunday. A pattern change moves in late Monday and into the middle of next week: rain is likely from Monday night, March 30, through Wednesday, March 31, with the heaviest totals targeting the Coastal Ranges and the North Bay. Some spots could see around an inch, with a small chance of 2 inches in the western Sonoma hills, according to the National Weather Service San Francisco.
What To Know Right Now
Got outdoor plans? Lean into the warm afternoon hours, but skip strenuous activity in direct sun and pack extra water and shade for kids and pets. Boaters and small-craft operators should time trips around advisory conditions, and anyone with lightweight outdoor gear or patio furniture should tie things down before the gustier period that arrives Friday morning.
