The Bay Area is heading into a sunny, unusually warm Thursday, with regional temperatures reaching near 82 degrees. Skies should stay mainly clear across the region, and rain is not expected. Warm weather continues Friday before cooler, more fall-like conditions arrive Sunday.

Thursday And Friday Bring The Heat

Thursday temperatures are expected to climb into the upper 70s to low 80s around midday, with light northeast winds shifting west later. Thursday night stays clear with a low near 59 degrees.

Friday is expected to stay warm, with plenty of sunshine. The National Weather Service expects warm conditions to hold into Saturday across the region.

Fire Risk Rises In The Hills

A Fire Weather Watch begins Thursday evening and continues through Friday morning for the North Bay interior mountains, not San Francisco itself. The National Weather Service says higher elevations around the Bay Area could still see elevated to near-critical fire weather conditions, with very dry air and gusts of 20 to 30 mph possible in the hills.

That combination can make it easier for a small spark to become a fast-moving fire. Anyone spending time in the hills should avoid outdoor flames, use extra care with equipment that can create sparks, and follow any local fire restrictions.

Cooler Weather Arrives Sunday

The weekend turns cooler after Saturday, with a regional cooling trend beginning Sunday. Cooler conditions are expected to continue into early next week.

Coastal neighborhoods may feel cooler than inland parts of the city, especially once afternoon winds strengthen.

Rain Chances Return Next Week

Rain chances are expected to increase Tuesday through late week.

Rain chances remain modest, but the broader pattern points to cooler, moister weather across the Bay Area next week. Until then, warm weather Thursday and Friday will make water, shade, and a little patience with the forecast’s sudden mood swings useful companions.
