San Francisco woke up under clear skies today, with temperatures around 50°F at SFO, but that calm start will not last. An offshore push is set to crank up north-northwest winds through the late morning and into the afternoon. Expect a high near 67°F, with sustained NNW winds of 15 to 21 mph and gusts up to about 32 mph, making exposed shorelines and hilltops feel a lot gustier than the interior neighborhoods.
Afternoon Winds Pick Up
Winds will ramp up quickly after mid-morning, peaking in the late morning and early afternoon before easing tonight. High-profile vehicles and cyclists should use extra caution on bridge approaches and other exposed routes, and anyone on a particularly breezy block may want to tie down patio furniture and loose decorations. This guidance comes from the National Weather Service.
Marine And Ferry Cautions
Small craft advisories and gale warnings cover much of the coastal waters into Friday and parts of Saturday, producing very rough seas, 12 to 15 feet in spots, so small-boat operators should stay in port or seek shelter. Ferry riders should check carrier alerts before heading to terminals, and mariners should expect hazardous conditions on exposed launches. Operator sites such as Golden Gate Ferry and the Port of San Francisco provide real-time service updates.
Weekend Warmup
The offshore pattern will let temperatures climb into the 70s tomorrow and Saturday, with a peak near 78°F on Saturday and lighter winds by Sunday. Nights will run cooler, in the low-to-mid 50s, with a modest cooldown early next week as the flow turns more zonal.
