San Francisco finally got the memo that it is almost spring. Sunshine and a noticeable warmup settled over the city today with clear skies and morning temperatures in the low 60s. By midafternoon, the city is expected to climb into the upper 70s, making this one of the warmest days in the short-term forecast. Overnight lows should stay mild, generally in the low to mid 50s across town.
Temperatures are forecast to reach a high near 77°F this afternoon, with more sheltered inland neighborhoods possibly sneaking into the low 80s while waterfront areas stay cooler. Light north-northeast breezes of about 5 to 10 mph are expected across most neighborhoods, with stronger gusts limited to exposed ridges and the immediate coast. The mild, sunny setup is part of a short-lived warm spell, according to the National Weather Service.
Afternoon Winds Pick Up
Across the flats, winds should generally remain on the lighter side, but exposed hilltops and the coastal fringe will feel noticeably gustier this afternoon. Offshore flow has pushed back the marine layer, allowing inland temperatures to jump, though winds are expected to ease overnight as the pattern relaxes. Anyone planning time on bridges or right along the shore should secure loose items and stay alert for stronger crosswinds.
Marine and Boating Advisory
Small-boat operators will want to think twice before heading out. A Small Craft Advisory remains in effect for the northern outer waters through early tomorrow, with rough seas and northerly breezes making conditions hazardous for smaller vessels. The advisory is currently set to expire at 3 AM PST Sunday for the stretch from Point Arena to Point Reyes, 10 to 60 nautical miles offshore, according to the National Weather Service. Anyone eyeing a trip on the water should check with ferry operators and other carriers before heading to the docks.
Through The Week
Looking ahead, dry conditions are expected to hang on into the coming week, with a shallow marine layer returning next Monday morning and bringing patchy pre-dawn fog to lower-lying neighborhoods. Highs are forecast to dip into the mid-60s before a gradual warm-up nudges temperatures back toward the low 70s by midweek. Overall, the pattern is expected to stay dry through the extended forecast, which should ease any immediate fire-weather concerns…
