October is one of the best months of the year to visit San Francisco. The weather is warm and clear, with none of the annoying summer fog that keeps things cloudy and cold-feeling. The tourist crowds are gone, and everything is easier to get into.

What to Pack

With less fog and only a small chance of rain, light layers will usually be plenty.

An extra jacket or layer will feel nice in the evening. Rainfall starts to become more likely, and it's always best to check the forecast. Also pack sunscreen and sunglasses. When the UV Index (amount of skin-damaging radiation) exceeds 6 to 7, you need both skin and eye protection.
