San Francisco, Calif. – The city wakes under a pale, golden sunrise — the kind that spills light over the Bay Bridge and catches the calm, glassy water below. After a stretch of fog-free mornings, the Bay Area is set for another run of postcard-perfect fall weather this week, with mild breezes and clear skies carrying through Halloween.
According to the National Weather Service in Monterey, a stable ridge of high pressure will keep the region dry and sunny through at least Friday. Highs climb into the mid-70s for San Francisco and the upper 70s inland around Concord, Walnut Creek, and Livermore. Winds stay light from the northwest, with cool, crisp nights dipping into the 50s — a classic late-October setup.
The calm spell means ideal conditions for outdoor activity and Halloween events. Trick-or-treaters Friday evening can expect temperatures in the mid-60s at dusk, falling to around 58°F later in the evening. Coastal communities such as Half Moon Bay and Pacifica may feel slightly cooler with a light breeze off the water, while East Bay neighborhoods stay warmer. Layers are still a good idea for families heading out after dark.
Looking beyond Halloween, a subtle shift arrives this weekend as high pressure weakens and onshore flow returns. Clouds could build by Sunday, marking the first hint of a cooler, breezier start to November. For now, the Bay enjoys its late-autumn glow — quiet, sunlit, and briefly timeless before the season turns. After all, a chilly November always finds its way back to the coast.
