San Francisco in August
Not the best time
August delivers more of July's disappointing weather at equally outrageous prices. Smart locals escape to warmer spots like the Mission District or head entirely out of the city for actual summer weather.
Weather
August continues July's foggy pattern with thick marine layer most mornings and evenings. Temperatures remain stuck in the mid-60s while wind howls through downtown corridors. The fog starts lifting earlier in the afternoon, offering brief windows of sunshine.

All Months
September through November is San Francisco's secret season. The fog finally lifts, temperatures hit the 70s, and you can actually see the Golden Gate Bridge most days. October especially shines — locals call it their summer.
Summer disappoints first-time visitors. June through August brings thick fog and 60-degree highs. Mark Twain never actually said that thing about the coldest winter, but he should have. Pack layers always.
Spring (March to May) stays cool but clear. Cherry blossoms bloom in Japantown around April, and hotel rates haven't hit peak season yet.
Winter gets a bad rap, but December through February offers the city's most dramatic weather. Storm systems roll in off the Pacific, clearing to reveal snow-capped mountains across the bay. Just bring a serious rain jacket.
Here's the thing about SF weather — microclimates rule everything. It might be 75 and sunny in Mission Dolores while Karl the Fog devours the Sunset District. Always check neighborhood-specific forecasts.
