San Francisco woke up today under a familiar cool marine layer, with early morning temperatures hovering near 55°F in many neighborhoods. Clouds are expected to thin by midmorning, giving way to mostly sunny skies and a comfortable holiday afternoon, with highs around 68°F.

Afternoon Winds Pick Up

West-southwest winds will ramp up this afternoon, generally in the 6–13 mph range with gusts to about 18 mph and locally stronger gusts of 20–25 mph through gaps, passes and the Salinas Valley. The breeze could make bridge crossings and waterfront fireworks viewing feel noticeably cooler than the thermometer suggests, so plan on that extra layer if you are heading out.

Marine Layer Returns Tonight

Stratus is expected to rebuild along the immediate coast this evening, with overnight lows dipping back into the mid-50s. A Small Craft Advisory remains in effect for waters north of Point Reyes into the overnight hours, and mariners are urged to avoid exposed waters and check the local forecast, according to the National Weather Service.

Holiday Plans And Fireworks

The city's Golden Gate fireworks show is scheduled for about 9:30 PM, and officials are warning of heavy crowds and a temporary bridge closure around the display. 

Looking Ahead

Tomorrow looks a bit cooler with a slight chance of isolated showers in the morning and afternoon, though forecasters say measurable rain is unlikely. Temperatures are expected to dip a few degrees tomorrow and next Monday before a gradual warming trend develops inland later in the week.

Whether you are boating, barbecuing or setting up for fireworks, check the marine forecast before leaving the dock, follow local rules and keep a fire extinguisher or a ready water source close by when grilling or using pyrotechnics.
