Today started on the chilly side in San Francisco, with downtown temperatures in the mid-50s. By late afternoon, though, sunshine is set to crank up the temperatures in inland neighborhoods into the upper 70s and low 80s. Winds that are light and variable early will swing to the north-northwest, then turn onshore, with afternoon gusts up to about 18 mph. Coastal neighborhoods and the waterfront will stay noticeably cooler, so if you are heading to the water this evening, do yourself a favor and bring a sweater.
Afternoon Heat Inland, Cool Coast
According to the National Weather Service, the official high for San Francisco is near 82°F today, with many interior Bay Area valleys also climbing into the 80s, while the coast hangs back in the 60s. Temperatures are expected to slide to the low 70s on Wednesday as onshore flow and the marine layer begin to rebuild. Overnight lows will land in the low to mid 50s across the city.
Breezy Bay And Marine Advisories
The National Weather Service notes that Small Craft Advisories remain in effect for portions of the outer coastal waters, including areas from Pigeon Point to Point Pinos, and that advisories north of Point Arena to Point Reyes extend into Wednesday evening, with details varying by marine zone and time. Onshore breezes this afternoon could gust to about 18 mph on land and near 20 knots (about 23 mph) over parts of the bay. Mariners and small-boat operators are urged to steer clear of exposed waters until conditions calm down.
What This Means For Your Plans
Heading inland this afternoon means sunny, warm weather that is tailor-made for parks, patios, and lingering outside a little longer than you planned. Sticking closer to the coast, you will want an extra layer handy for cooler air and those stronger evening winds. Commuters using the bay or ferry services should allow a bit of extra time and check with operators if crossing during peak gusts. Anyone planning marine outings or late-night waterfront events should keep an eye on updated forecasts as conditions shift.
