Today, San Francisco woke up to clear skies and mild 58°F air, with the city expected to warm into the low 70s by this afternoon. Sunshine and dry conditions will rule through the weekend, although north-northwest breezes will make shorelines and hilltops feel a lot gustier than the more sheltered neighborhoods.
Afternoon Winds Pick Up
North-northwest winds are set to ramp up through late morning, with sustained speeds around 9 to 16 mph and peak gusts near 28 mph expected across the city this afternoon. Along the coast and on higher ridges, it will be a different story, with forecasters calling for gusts of 40 to 50 mph in exposed spots and briefly stronger blasts on the highest peaks. That is the time to lock down the patio chairs and be ready for crosswinds on bridges. According to the National Weather Service, this breezy pattern should hang on into Saturday before easing on Sunday.
Marine Outlook
Out on the water, Small Craft Advisories and Gale Warnings stretch across much of the coastal zone into tonight and early Saturday, with very rough seas of 12 to 15 feet in exposed areas making small-boat travel hazardous. Mariners, small-boat owners, and even regular ferry riders are urged to check with their carriers before heading out, per the National Weather Service.
Weekend Warmth And What To Expect
Temperatures will keep climbing through the weekend, with highs near 77°F on Saturday and about 76°F on Sunday. Inland valleys will run warmer, and a few interior spots could flirt with 80°F. Skies stay mostly clear and dry into midweek, although a shallow marine layer may creep back in overnight Sunday into Monday, bringing some patchy pre-dawn fog. Outdoor plans look good overall, but you will want a light layer near the water, where wind and marine chill will bite the most, as noted by the National Weather Service.
