San Francisco is set for a bright, sunny Sunday with highs near 77°F once the morning marine layer and patchy fog burn off — a rare treat for a city where Karl the Fog usually calls the shots. Get outside between late morning and early evening, but pack a light jacket for tonight, since temperatures drop back to around 57°F after sunset.
Today’s Setup
According to the National Weather Service, an upper-level disturbance passing over the Pacific Northwest is keeping the marine layer compressed to about 500 feet and hugging the San Mateo and Central Coast this morning, meaning cloudy skies and patchy dense fog — even some coastal drizzle — through mid-morning. Skies clear out after that, leaving a mainly sunny afternoon across the city. Wind stays light out of the southwest at 3 to 13 mph, with gusts up to 20 mph possible by afternoon.
Best Window To Be Outside
Wait until after 11 AM PT for the fog to lift before heading to Golden Gate Park, Ocean Beach, or the Marina Green — that’s your sunniest, warmest stretch before temperatures ease back down in the evening. If you’re near the coast, watch for those afternoon gusts and secure any patio umbrellas or a garden flag pole heavy duty setup before they catch wind.
Rain, Wind, Fire, Or Heat Risk
No rain is expected today. The bigger story is inland: the National Weather Service has flagged a near-critical fire weather threat across the interior North and East Bays and moderate HeatRisk for interior valleys, where highs could reach the mid-90s to low 100s — a stark contrast to San Francisco’s mild 77°F. If you’re headed inland, be extra careful with anything that could spark a fire. Along the immediate coast, hazardous beach conditions continue into the afternoon, with an increased risk of sneaker waves and rip currents — stay well back from the waterline at Ocean Beach.
What To Wear Or Bring
Layer up: sunglasses and a light shirt for midday, plus a hoodie for the evening chill once the fog creeps back in. Sun protection matters even with fog around — Score a UPF 50+ Sun Hoodie for Just $5 This Fishing Season before your next outing on the water or the pier.
Game Day And Weekend Events
The Oakland Athletics host the Detroit Tigers today, a good excuse to break out an Oakland Athletics jersey or Oakland Athletics fitted cap. Tonight, the Golden State Valkyries take on the Toronto Tempo at Chase Center — Get tickets on SeatGeek if you’re heading down. Looking ahead, the Lionel Richie and Earth, Wind & Fire concert hits Chase Center Thursday, August 6, followed by Meghan Trainor’s Get In Girl Tour there Saturday, August 8 — pick up a Lionel Richie t-shirt or Meghan Trainor t-shirt, and Find tickets on StubHub while seats last. Outside Lands also takes over Golden Gate Park on Friday, August 7, so expect crowds and road closures near the park that day.
Dinner Tonight
With clear skies and comfortable temperatures, tonight’s a solid night to grill — pasta or stir-fry both work fine if you’d rather stay indoors. A hard cooler 52 quart keeps drinks cold if you’re eating in the backyard. Need ingredients? You can order groceries on Amazon and have everything for tonight’s dinner delivered to your door.
Next Few Days
Monday looks like a repeat performance as the upper-level trough pushes east and high pressure builds back in — expect sunny skies near 77°F again, with interior temperatures possibly climbing a few more degrees. Fire weather concerns linger into Monday for the East Bay hills, so stay alert if you’re headed that way.
