At 4:43 AM today, temperatures near San Francisco International Airport were holding around 55°F under a stubborn marine layer. That sets the stage for a classic summer pattern: cool, partly cloudy mornings along the waterfront and sunnier, breezier afternoons inland, with highs topping out in the upper 60s today.
Afternoon Winds Pick Up
By afternoon, southwest winds will crank up, generally 7 to 14 mph with gusts up to around 20 mph along the water. Expect blustery conditions on exposed headlands and bridges. A Small Craft Advisory is in effect for portions of coastal waters through Friday, so mariners should plan accordingly, according to the National Weather Service.
Holiday Weekend Outlook
Forecasters say the persistent cool pattern will shift into a gradual warming trend Friday and into the holiday weekend, with inland spots seeing the biggest bump. Some inland pockets south and east of the Monterey Bay could warm into the mid- to upper 80s, while the immediate coast hangs back in the mid-60s.
What This Means For You
Layer up for those early morning commutes, then be ready to shed a layer when the sun and breeze kick in later in the day. If you're heading out on the water, keep an eye on local marine forecasts and respect advisories through Friday. Beachgoers should be ready for cool air and gusty surf near exposed points rather than full-on heat wave vibes.
