Running in San Francisco: what the weather does to your run
San Francisco's microclimates and signature fog keep summers cool and windy when the rest of the state bakes. The feels-like is often driven by wind off the bay more than the air temperature, so a light wind layer earns its place most mornings. Dramatic heat is rare; raw, blustery cool is the default.
