San Francisco’s weather today, Friday, is mostly sunny with a high near 66°F, dipping back to around 64°F by afternoon as the marine layer muscles back in — plan outdoor time before the gray rolls over Ocean Beach and the Marina tonight.

Today’s Setup

The National Weather Service says the marine layer is officially back, with a 1,200-foot-deep layer of cool, moist air already forming stratus from San Francisco down toward the Santa Cruz county line. Expect a mostly sunny day with west-southwest wind 7 to 15 mph, gusting as high as 22 mph — hang onto your hat near Crissy Field. Overnight lows drop to around 55°F.

Best Window To Be Outside

Midday into early afternoon is your clearest, calmest stretch before winds pick up and fog fills back in toward evening. If you’re headed to the Presidio, Golden Gate Park, or the Embarcadero, get out there before the breeze builds.

Rain, Wind, Fire, Or Heat Risk

No rain to worry about — just a 1% chance today. The main story is wind and cool, humid air working back into the city through the weekend, per the NWS forecast discussion. No severe weather or excessive rainfall risk is flagged for the Bay Area today.

What To Wear Or Bring

Layer up: a breathable layer like ventilated workout shorts men for daytime activity, plus something wind-resistant for the evening chill. If you’ve got a patio setup catching those gusts, an umbrella base 50 lb keeps things from tipping over.

Weekend Events & Games

It’s a busy stretch around the Bay. Tonight, comedian Nate Bargatze: Big Dumb Eyes World Tour plays SAP Center in San Jose — indoor, so the fog won’t matter. Saturday, Ella Mai brings her Do You Still Love Me? Tour to Bill Graham Civic Auditorium; grab tickets on StubHub and look for an Ella Mai t-shirt or Ella Mai hoodie if you’re going. Looking a few days out, the Golden State Valkyries host the Washington Mystics at Chase Center on July 20 — find tickets on SeatGeek for that one. The Oakland Athletics also open a series against the Washington Nationals this weekend, weather-friendly for tailgating with mild temps and light wind.

Dinner Tonight

With cool, breezy evenings back in the mix, this is prime weather for something warm off the grill or stovetop — a pasta dish or stir-fry both work great tonight. If you want to try something different, the tri-tip smoking hack is worth a look for weekend grilling. Need ingredients? You can order groceries on Amazon and have everything for tonight’s dinner delivered to your door — Amazon Fresh groceries makes it easy to skip the store trip.

Next Few Days

Saturday holds steady with a high near 66°F and partly sunny skies, cooling to near 54°F overnight. Expect the marine layer to stick around into early next week, keeping mornings misty and afternoons mild across the city.

Upcoming Home Games
