San Francisco in May
Good time to visit
May offers San Francisco's most reliable weather before the summer fog machine kicks into high gear. Bay to Breakers turns the city into a moving party, but the rest of the month feels perfectly balanced.
Weather
May brings classic San Francisco spring weather with warm, dry days and cool, foggy mornings. The marine layer begins its summer routine, burning off by midday to reveal blue skies. Temperatures climb into the pleasant mid-60s with virtually no rain.

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.
