San Francisco started today, on a mellow note, waking up to mostly clear skies and temperatures hovering near 55°F at the official observing site. Sunshine is set to spread across the city through the afternoon, sending many neighborhoods toward highs in the mid-70s. Along the waterfront, though, a fresh west breeze will make exposed shorelines and hilltops feel noticeably gustier than the more sheltered parts of town.
Afternoon Winds Kick Up Across The City
West winds are expected to run about 5 to 13 mph this afternoon, with gusts reaching roughly 20 mph, especially along exposed shorelines and ridge tops. Out on the water, conditions turn rougher. Small craft advisories and gale warnings are in effect for parts of the coastal waters from this afternoon until tomorrow, creating very rough seas and hazardous conditions for smaller boats. Recreational boaters are being urged to avoid exposed launches and to check notices before heading out, according to the National Weather Service.
Weekend Warmth Hangs On
The mild spell keeps rolling into Thursday and Friday, with highs climbing into the low 70s on Thursday and near 75°F on Friday before easing a bit over the weekend. Overnight lows are expected to settle in the low 50s. Interior neighborhoods and the Central Coast will run warmest, while the immediate coastline stays a few degrees cooler under a shallow marine layer. This stretch is part of a broader early-season warm pattern that set records earlier in the month, per AP.
Looking Ahead To Next Week
Early next week, a deeper Pacific trough is expected to move in, bringing a chance of light rain from Monday night into Tuesday. Ensemble guidance currently points to roughly 0.5 to 1.0 inch of rain across the Bay Area over the course of next week. Daytime highs are forecast to cool into the 60s on Monday and drop into the widespread 50s on Tuesday as the system passes through.

For now, drivers and cyclists should keep an eye on gusty crosswinds near bridge approaches this afternoon, and anyone with outdoor furniture or loose items on exposed balconies should secure them. Those planning a boat trip should be prepared for possible cancellations or delays and confirm with carriers and ports before heading to the terminals.
