San Francisco, CA – A surge of unusual warmth is pushing San Francisco toward its warmest March on record, with daytime highs climbing well above seasonal norms through the weekend.
According to the National Weather Service Bay Area office, average temperatures through late March are trending near 62 degrees, putting 2026 on pace to surpass records dating back to 1875. Forecasters say a strong ridge of high pressure is driving the heat, limiting coastal cloud cover and allowing inland warmth to spill toward the shoreline.
Across the Bay Area, cities like Oakland and San Jose are seeing highs in the upper 60s to mid-70s, while downtown San Francisco pushes into the upper 60s. Inland valleys, including Contra Costa and Santa Clara counties, could briefly touch the upper 70s during peak afternoon hours.
The warmth may impact energy demand and increase early-season fire concerns in drier hills. Officials urge residents to stay hydrated, avoid outdoor burning, and use caution with equipment that could spark fires.
Conditions remain dry and stable into early next week, with cooler air expected to gradually return by midweek. Additional advisories may be issued if fire risk increases.
