Great question and one we get asked a lot here at Dylan’s Tours.
San Francisco doesn’t really follow the typical weather pattern. While most people assume summer is the best time to visit, locals know that the real sweet spot is in September and October. That’s when we get the warmest days, the clearest skies, and a little break from our famous fog (we call him Karl, by the way).
Spring, especially from April to early June, is another great window. The city’s in bloom, the energy is up, and the crowds aren’t too overwhelming yet. Just make sure to pack layers—our microclimates can shift quickly.
If you’re looking for fewer crowds and good deals, visiting from January to March can be surprisingly enjoyable. It’s cooler, but places like Muir Woods are peaceful and serene with a bit of winter mist in the air.
Honestly, there’s never really a bad time to come, but if you want our local take, early fall and late spring tend to offer the best all-around experience. Whenever you visit, we’d love to help you explore the city like a local.
