San Francisco starts Friday, October 16, in the low 60s under clear skies, but the city is headed for one more unusually warm day before the Bay Area’s weather takes a sharp turn. Temperatures are expected to climb into the 70s to low 80s this afternoon, with sunny skies and little wind.

Friday’s Warm Weather Comes With Fire-Weather Concerns

The forecast calls for offshore flow and no rain in San Francisco. A Red Flag Warning remains in effect until 11 a.m. Friday for the North Bay Interior Mountains, while very dry conditions and elevated fire danger are expected to persist across higher elevations through Saturday, according to the National Weather Service.

For city residents, the main takeaway is simple: Friday will be hot and dry, especially away from the immediate waterfront. Anyone using outdoor flames or equipment that can create sparks should take extra care, particularly in the hills and other dry, windy areas.

Weekend Temperatures Drop Fast

Saturday stays sunny but cooler, with a high near 80 and an overnight low around 57. By Sunday, the high is about 66 degrees, with the marine layer returning and a more familiar fall feel to the city.

Light Rain Enters The Forecast Next Week

Monday will be mostly sunny with a high near 62, followed by a chance of rain at night. Tuesday brings a chance of rain and a high near 62. Light rain remains possible next week.

The broader pattern next week looks cooler and occasionally breezy, with onshore winds returning around the Bay Area. Rain amounts are expected to be light in lower elevations, but the forecast finally offers a break from the warm, dry stretch arriving Friday.
