San Francisco is waking up Saturday to mostly clear skies and temperatures around 59 degrees. Sunshine will take over the day, with temperatures reaching near 70 before easing into the upper 60s later. The catch is the wind, which will make exposed streets and waterfront areas feel noticeably cooler.

Afternoon Winds Pick Up

West winds at SFO will increase to 25 to 35 knots Saturday, with generally 25 to 35 mph gusts and locally higher gusts elsewhere. The National Weather Service in San Francisco says breezy onshore winds will continue into Saturday night before easing Sunday morning. A wind-resistant layer will be more useful than an umbrella for outdoor plans.

The latest update outlines the weekend forecast across the city. The outlook does not specify precipitation probabilities through the coming week.

Sunday Brings A Slight Rebound

Saturday night will stay mostly clear, with a low near 58 degrees and gusty winds continuing overnight. Lightweight patio items and decorations may need securing. Sunday should be calmer and warmer, with temperatures near the Bays in the upper 60s to 70s.

Temperatures should remain near to slightly below seasonal averages through the week. From Tuesday through Friday, the pattern should remain stable, with possible overnight and morning low clouds. The broader pattern should remain stable into the following week.

Boaters Face Rougher Conditions

The marine forecast is a different story from the calm-looking skies over land. A Small Craft Advisory is posted for San Francisco Bay north of the Bay Bridge from 9 a.m. Saturday to 9 a.m. Sunday, while stronger advisories cover other Bay Area and Monterey Bay waters.

Land-based San Francisco has no watches, warnings or advisories listed. Anyone heading to the waterfront should plan for shifting gusts, while boaters should check the latest marine forecast before leaving the dock.
