San Francisco is starting today in the upper 50s under a compressed marine layer, but the gray is expected to retreat by late morning. Mostly sunny skies will take over for the afternoon, with temperatures reaching near 70 before a cooler, breezier evening settles in.
Fog Gives Way To Afternoon Sun
The city's classic fog-to-sun routine is on schedule, with mostly cloudy skies early and clearer conditions building through the afternoon. The National Weather Service forecasts no rain, a high near 70 degrees and temperatures easing into the upper 60s later in the day.
West-southwest winds will run about 5 to 13 mph, with gusts reaching 18 mph. The breeze is expected to strengthen through the afternoon and evening, making the waterfront and exposed neighborhoods feel cooler than the thermometer suggests.
Cooler Pattern Arrives Thursday
Tomorrow and Friday will be partly sunny, with highs near 68 degrees, followed by another mostly sunny Saturday near 70 degrees. Next Sunday brings a more noticeable cooldown, with a high near 66, while next Monday and Tuesday stay in the mid-60s.
Overnight lows will remain fairly steady in the upper 50s, generally 57 to 58 degrees. Nights will trend mostly cloudy, while daytime rain chances remain near zero through next Tuesday.
Small-Craft Advisories Cover Parts Of Coastal Waters
Boaters should take extra care this afternoon, when small-craft advisories begin for portions of the outer coast. The NWS forecast discussion calls for locally strong northwesterly breezes and periodically hazardous conditions for small craft through the weekend.
No land-based watches or warnings are posted for San Francisco. Inland hills and other elevations above about 1,000 feet will be warmer and much drier than the city, so outdoor plans there should account for low humidity even as winds remain relatively light.
