San Francisco is waking up to a mostly sunny Sunday with a high near 63°F — classic Bay Area May, which means layer up because Karl the Fog has opinions about your plans. Here’s what to expect this Memorial Day weekend. Check the full San Francisco weather forecast for updates.
Today’s Setup
The National Weather Service expects mostly sunny skies through midday, with west-southwest winds 5 to 12 mph. Marine layer clouds along Ocean Beach, the Sunset, and the Richmond should clear by mid-morning. Microclimates will be in full play — the Mission and Noe Valley could run a few degrees warmer than neighborhoods near the Bay. High near 63°F, with temps easing back to around 61°F by late afternoon as onshore flow builds.
Best Window To Be Outside
Mid-morning to early afternoon — roughly 10 AM to 2 PM PT — is your sweet spot. Perfect for a stroll across the Golden Gate, a picnic at Dolores Park, or a run along the Embarcadero. After 2 PM, clouds increase slightly but nothing dramatic enough to cancel your plans.
Allergy Alert
May is prime pollen season in the Bay Area. Today’s light onshore breeze can carry tree and grass pollen into neighborhoods across the city. Consider an allergy relief nasal spray before heading out for long stretches. At home, running a HEPA air purifier helps keep indoor air clean on higher-pollen days.
Gameday Weather: Giants at Oracle Park
The San Francisco Giants host the Chicago White Sox today (May 24) at Oracle Park — game-time temps will be in the low 60s with the bay breeze making it feel cooler. Bring layers. A San Francisco Giants jersey or San Francisco Giants fitted cap will keep you warm and show your colors. Browse outdoor gear deals to top up your game-day kit. Get tickets on SeatGeek if you still need seats. On Memorial Day (May 25), the Giants host the Arizona Diamondbacks under similar conditions: partly sunny, near 62°F with gusts up to 21 mph — another great excuse to bundle up at the waterfront ballpark. Also worth penciling in: Yellowcard plays Bill Graham Civic Auditorium on May 27, an indoor show with no weather worries — Find tickets on StubHub before they sell out.
Next Few Days — And Tonight’s Dinner
Cool, breezy evenings call for something warming and easy. A pasta dish or stir-fry fits perfectly — and you can order groceries on Amazon to have everything at your door in time for dinner. Feeling ambitious at the grill? Our guide on smoke tri-tip like brisket is worth a read even on a cooler Bay Area evening. As for the week ahead: Memorial Day (Monday) brings partly sunny skies and a high near 62°F with gusts up to 21 mph. Tuesday turns cooler and windier as an upper-level trough arrives; the National Weather Service expects gusts of 30 to 40 mph along the coast and ridgelines, with hazardous small craft conditions on the Bay. Wednesday into Thursday, an inside slider pattern kicks off a gradual warming and drying trend. By the end of the week, onshore flow returns with more seasonal temperatures.
