San Franciscans woke up today to a very familiar split personality: low clouds and patches of fog draped along the coast while inland neighborhoods quietly crept into the mid to upper 60s. Morning lows are in the low 50s across much of the city, before sunshine nudges afternoon highs to about 67°F.
Afternoon Winds Pick Up
By this afternoon, an onshore west-southwest breeze will kick in, with sustained winds of 5–10 mph and gusts reaching around 25–30 mph near the Golden Gate and other coastal gaps. That will sharpen the divide between cool, foggy shoreline spots and warmer inland pockets, and it may help shove the marine layer farther inland this evening. This timing and wind guidance come from the National Weather Service.
Foggy Mornings, Sunny Afternoons
Marine layer clouds and patchy fog will be most stubborn near the shoreline and in low-lying westside neighborhoods through the morning before giving way to sunshine in many areas by midday. Expect chilly, damp starts that flip to comfortable afternoons that work well for errands, dog walks, or a quick park run.
Weekend Cooling And Light Rain Chances
By tomorrow, a subtle pattern shift should allow cooler onshore flow to move in, and a low is expected to slide over the Bay Area sometime next Sunday night into Monday. That system could squeeze out some drizzle or scattered light rain. Most neighborhoods are only looking at trace amounts to a few hundredths of an inch, so it is more of a plan-with-flexibility situation than a cancel-everything event. If you have outdoor plans late next Sunday, it is worth having a backup option or a quick weather-aware tweak ready.
Boaters And Commuters
Small Craft Advisories remain in effect for parts of the coastal waters through tomorrow, with the northern outer waters building seas of 10–12 feet and locally choppy conditions. Recreational boaters should take it seriously, use caution, and wear life jackets. On land, drivers should budget extra time for slow, fog-slicked morning commutes and be ready for gusty conditions on exposed bridges. We will update the forecast if any watches or advisories change.
