After the holiday weekend at the beginning of the month, San Francisco residents breathe a sigh of relief that peak tourism season has ended. However, this is actually a perfect time for tourists to visit the Golden Gate City.
San Francisco Weather in September
September is arguably one of the best months to visit because of the weather. Around this time, San Francisco usually has clearer skies (compared with the more foggy months) and warmer average temperatures than in July and August. It's also usually one of the city's driest months.
Plus, you can expect about 12 hours of daylight for exploring the city.
- Average High Temperature: 73°F/23°C
- Average Low Temperature: 56°F/13°C
- Rain & Clouds Index: 0.26 inches (0.7 cm) rain, 72% sunshine
Averages are helpful for planning ahead, but check the San Francisco weather forecast before you leave home to get a more definitive idea of what the weather will be when you're there.
What to Pack
With less fog and no rain, light layers will usually be plenty. And an extra jacket or layer will feel nice in the evening.
You won't need dress clothes unless you're attending an event that requires them, and even at most nice restaurants, you can get away with jeans and a nice top. You might find a scarf useful in case it's extra chilly.
For women, add versatility to your wardrobe by packing dresses that look good with leggings or tights. They're easy to carry in your bag all day and slip them if it gets chilly or after dark.
Rainfall is generally unlikely, but if your extra jacket is also rainproof, it can do double duty.
