San Francisco starts Wednesday, August 5, under a slight chance of drizzle and low stratus, but skies clear to mostly sunny with a high near 72°F by afternoon — bring a light layer for the gray morning, then get outside once the sun wins out. The National Weather Service in Monterey notes the marine layer sitting around 1,000 to 1,200 feet overnight, so patchy drizzle and fog are possible into Wednesday morning before burning back to the coast a bit later than usual.
Today’s Setup
Overnight lows dip to near 58°F with a slight chance of drizzle after 2 AM PT and southwest wind around 6 mph. By midday, west-southwest wind picks up to 5-12 mph with gusts as high as 18 mph, and temperatures actually ease back toward 69°F in the afternoon as the sea breeze fills in — classic San Francisco.
Best Window To Be Outside
Midday through late afternoon is your sweet spot, once the stratus lifts off the Sunset and Richmond districts and Ocean Beach. Golden Gate Park and the Marina will feel pleasant by early afternoon, though Twin Peaks and the Golden Gate Bridge could hang onto breezy, cooler conditions longer thanks to that onshore flow.
Rain, Wind, Fire, Or Heat Risk
No real rain is expected in the city today — just morning drizzle odds under 5%. The bigger story from the NWS forecast discussion is inland: an elevated fire weather threat continues through midweek across the interior North and East Bay, plus the Diablo and Santa Lucia ranges, with critical fire weather conditions developing Friday and Saturday. San Francisco proper isn’t in that zone, but expect it to shape air quality conversations later in the week if smoke drifts in. Keep an eye on official NWS updates if you’re heading toward those interior areas.
What To Wear Or Bring
Layer up for the morning fog with a packable rain jacket, and toss a compact travel umbrella in your bag just in case that drizzle lingers past sunrise. If you’re hiking Golden Gate Park’s trails or the coastal bluffs, waterproof hiking boots handle the damp morning grass well. Wind off the water can chap lips fast on the Embarcadero, so lip balm SPF moisturizing is worth keeping in your pocket. Once the sun breaks through, a hammock with stand in a sunny backyard or Dolores Park-style spot makes the most of the afternoon warmth.
Big Nights In The Bay
AC/DC’s POWER UP TOUR 2026 rocks Levi’s Stadium tonight, August 5 — Find tickets on StubHub or Get tickets on SeatGeek if you’re heading down to Santa Clara, and grab Official team gear on Fanatics for the road trip. Thursday, August 6, brings the Lionel Richie and Earth, Wind & Fire show to Chase Center, with mild evening temps in the upper 50s. Then Meghan Trainor plays Chase Center August 8 — pick up a Meghan Trainor t-shirt before you go.
Tonight’s Dinner
With cool, foggy evenings sticking around, this is prime comfort-food weather — think slow cooker chili or a hearty beef stew simmered in an enameled cast iron Dutch oven, or lean on a programmable slow cooker to have dinner ready when the fog rolls back in. Need ingredients? You can order groceries on Amazon and have everything for tonight’s dinner delivered to your door.
Next Few Days
Thursday repeats Wednesday’s script — stratus returns Wednesday night, clearing to another mostly sunny 72°F afternoon. By Friday, a building ridge compresses the marine layer to around 500 feet, and Moderate HeatRisk returns for the workweek’s end, mainly for interior valleys rather than the city itself.
