San Francisco gets one more sunny, mild day Monday before a cooler pattern settles in across the city. Temperatures should climb into the low 70s, while west winds pick up through the afternoon. The bigger change arrives after sunset, when the marine layer begins rebuilding and midweek temperatures start to slip.
Sunny Monday, Breezier By Afternoon
Monday's forecast calls for mostly clear skies, with coastal temperatures in the 60s and 70s. According to the National Weather Service, west winds at San Francisco International Airport will be 5 to 10 knots, increasing to 15 to 25 knots from the afternoon into the evening. Breezier conditions are expected later in the afternoon.
Cooler Midweek, Marine Layer Returns
Monday night will stay mostly clear, with a low around 58 and onshore flow returning. Tuesday through Thursday should bring cooler conditions, with Wednesday highs in the 60s and 70s. Coastal clouds and fog have a better chance of pushing back into the city Tuesday morning as the marine layer returns.
The second half of the week brings temperatures trending back toward seasonable levels next weekend. Rain chances remain near zero through the middle of the following week.
Light Jackets Still Belong In The Forecast
For outdoor plans, Monday afternoon looks comfortable in the sun but breezier near the waterfront and on exposed streets. A light jacket will be useful after sunset, with patchy coastal fog also possible late Thursday night into early Friday morning.
This latest outlook shifts the focus from the warm spell and weekend breeze covered in Hoodline's earlier forecast to a more noticeable midweek cooldown. No land-based watches, warnings or advisories are listed for San Francisco, though conditions remain breezy enough for boaters to check coastal advisories before heading offshore.
