San Francisco started today under a familiar gray blanket, with low clouds hugging the coast and temperatures in the low 50s at local airports. Downtown and other inland pockets, already sliding into the mid 60s by early morning, will see the sun break through by late morning. Expect a high near 69°F and a west wind kicking up through the afternoon. The marine layer will keep the immediate shoreline on the cool side while inland neighborhoods steadily warm into the weekend and early next week.
Weekend Warm-Up, Monday Looks Hot
Mostly sunny skies will help push city temperatures into the upper 60s today, then into the low 70s tomorrow and next Sunday. The bigger story arrives next Monday, when many inland valleys could jump into the 90s. Forecasters say next Monday should mark the peak of this warm spell, and they caution that the inland heat risk will become moderate, so people in sensitive groups should plan ahead. Overnight lows will hold in the low to mid 50s through the weekend, which will offer at least some relief from the daytime heat, according to the National Weather Service.
Heat Safety And Cooling Options
If you do not have air conditioning, the city wants you to think about where you will cool off before the hot day hits. San Francisco maintains a Heat Wave map and a list of potential cooling centers, including libraries and community centers that open during extreme heat events. Officials recommend limiting outdoor activity during the hottest hours and checking the Heat Wave map before you head out so you know where to duck in if you need a break from the heat. You can find the city’s guidance and resource map at SF.gov.
Afternoon Winds And Small Craft Advisory
West to southwest winds will ramp up this afternoon, with most of the Bay looking at sustained speeds of 7 to 12 mph and gusts up to 18 mph. Some ridge tops and exposed stretches of coastline could see gusts climbing into the 20s tomorrow. Mariners should pay attention to a Small Craft Advisory for Monterey Bay this afternoon from 3 PM to 9 PM, with additional advisories posted for nearby coastal waters into the weekend. Expect pockets of low clouds and reduced visibility near the water in the morning that should give way to clearer conditions as the day goes on, according to the National Weather Service.
