San Francisco is starting today with a cool, cloudy marine layer and temperatures in the upper 50s, but the city should brighten into a mild afternoon. The high is expected to reach about 68 degrees before west winds strengthen, making the waterfront and exposed neighborhoods feel noticeably breezier.

Clouds Fade As Afternoon Winds Pick Up

Low clouds may linger along the coast and around the morning commute before retreating later in the day. The National Weather Service forecast calls for west winds of 7 to 15 mph, with gusts reaching 22 mph, so a light jacket will still earn its keep after the sun comes out.

Rain is essentially off the schedule, with precipitation chances staying between zero and 2% through next Thursday, according to the National Weather Service. Tonight should be partly cloudy with another low near 58 degrees.

Sunny Weekend Brings A Brief Warm-Up

Tomorrow looks like the weekend standout, with sunny skies and a high near 71 degrees. Next Sunday will remain mostly sunny but a little cooler, topping out around 69, while overnight lows settle into the upper 50s.

The mild weekend will give way to a cooler pattern early next week. Forecast highs drop to about 68 next Monday, 65 next Tuesday, 67 next Wednesday and 68 next Thursday, keeping San Francisco comfortably below any serious summer heat.

Small Craft Advisories Cover Local Waters

Boaters should prepare for stronger northwest breezes and choppier conditions across nearby coastal waters and parts of San Francisco Bay. Small Craft Advisories are in effect for several marine zones from Friday morning and afternoon into early tomorrow, including waters north of the Bay Bridge.

For land-based plans, the forecast is straightforward: cloudy and cool to start, sunnier by afternoon, breezy near the bay, and dry all week. Tomorrow offers the best bet for a warm outdoor afternoon before the city settles back into its familiar jacket weather.
