San Francisco, CA is greeting Memorial Day with a cool high near 62°F, morning drizzle between 8 AM and 11 AM PT, and a San Francisco weather forecast that feels far more like March than the unofficial start of summer — grab your layers, because Karl the Fog is not done with us yet.
Today’s Setup
A 2,500-foot-deep marine layer is running the show, according to the National Weather Service. A slight chance of drizzle lingers from 8 AM to 11 AM PT, most likely along the coast and in neighborhoods like the Outer Sunset, the Richmond, and near Ocean Beach. Stratus retreats to the coast by late morning, giving the afternoon a mix of sun and clouds. Winds blow WSW at 6 to 14 mph with gusts up to 21 mph — nothing dangerous, but enough to feel raw by the water.
Giants Game Day: Oracle Park
The San Francisco Giants host the Arizona Diamondbacks today at Oracle Park, and conditions will be quintessential SF baseball weather: cool, breezy, and a little damp early. A packable rain jacket is smart for the first few innings, and a San Francisco Giants fitted cap keeps the bay breeze out of your face. Want to really rep the home team? A San Francisco Giants jersey completes the look. Still need seats? Get tickets on SeatGeek before first pitch.
What To Wear
Layers everywhere, but especially west of Twin Peaks. A high near 62°F with a marine breeze means shorts-and-T-shirt folks will be cold by the second inning. Light jacket, closed-toe shoes, and you’re set for most of the city.
Allergy heads-up: Damp coastal air elevates mold spore counts. If you’re sensitive, keep your allergy relief nasal spray handy, and run a HEPA air purifier at home tonight to scrub the air while you sleep.
Upcoming Events This Week
Yellowcard plays Bill Graham Civic Auditorium on Wednesday, May 27. Conditions should be improving by then — clearing skies with a high near 65°F — though WNW gusts up to 30 mph will make it breezy outside the venue. Snag a Yellowcard t-shirt and Find tickets on StubHub while they last. On Thursday, May 28, the Golden State Valkyries take on the Indiana Fever at Chase Center — fully indoors, so no weather concerns there.

Next Few Days
Tuesday is the windiest day of the week: WNW winds 10 to 20 mph with gusts up to 30 mph, especially along the coast and ridgelines — the National Weather Service flags hazardous small-craft conditions on the Bay. A cutoff low settles in Wednesday through Thursday, driving a gradual warming and drying trend. The far interior carries a low thunderstorm chance of 10% or less. By the weekend, conditions shape up much better for outdoor plans — a good window to browse outdoor gear deals and get the patio season started.
