SAN FRANCISCO, Calif. – Golden light and calm breezes will carry the Bay Area into a sun-filled stretch this week, as early October delivers classic fall warmth and crystal-clear skies. Monday and Tuesday promise ideal conditions for commuters, leaf-seekers, and pumpkin patch visitors across the coast and inland valleys.
According to the National Weather Service San Francisco Bay Area office, high pressure continues to lock in dry air through midweek, keeping daytime highs in the upper 70s and lows near 60°F. The calm setup means low wildfire risk and excellent air quality—welcome news for drivers along U.S. 101 and I-80. The agency advises motorists to stay alert for light west winds Tuesday afternoon that could gust to 15 mph across bridge spans and higher terrain.
Local parks and outdoor markets can expect steady crowds as the week remains warm and bright. Coastal fog will stay limited to early morning hours, retreating quickly inland. Residents planning outdoor Halloween decorating or weekend events should take advantage of the stable pattern before small rain chances return by late Friday.
By midweek, temperatures ease slightly as onshore flow strengthens. Cooler ocean air could trim highs into the upper 60s by Thursday, still comfortable for city walks and waterfront dining. The mild downturn signals the start of a broader transition toward typical late-October variability, with potential showers eyeing the weekend.
