When to Visit San Francisco

Choosing when to visit San Francisco, as well as deciding when to book, can determine the quality of the experience you'll have. Weather, crowds, and other seasonal factors play a significant role in how much your vacation will cost.

In general, good weather and big crowds mean higher prices and lower availability. Nevertheless, as San Francisco is packed with year-round activities and mild weather, any time can be a good time.

Typically, July and August have the highest citywide hotel occupancy rate, and business travel is at its height in September and October, when many of the largest conventions take place. These surges in visitor popularity reflect the American vacation system. With upswings during holidays and summer, hotels near popular tourist destinations such as Fisherman's Wharf will be booked up early. At these times, there will also be larger crowds at attractions, museums, and events.
