    Things That Look Like Fun to Do in September

    It's a good thing I can make lists because I find so many fun things to do that I'd forget them all. These are a few things on my "That Looks Interesting" list:

    Fringe FestivalIf you like the avant-garde, this one's for you, self-described as presenting "exciting, uncensored, indie theater."

    Autumn Moon FestivalThis fall festival celebrates the glories and mysteries of the moon

    Dragon Boat FestivalThe festival is one of the most important in Chinese culture and the boat races are fun to watch.

    Folsom Street FairSelf-described as a leather event, "providing the adult alternative lifestyle community safe venues for self-expression, emphasizing freedom, fun and frolic, while raising money to benefit San Francisco charities." You'll see lots of leather at this gay lifestyle...MORE fair (and lots of bare skin, too).

    Ghirardelli Square Chocolate Festival: A two-day chocolate celebration whose proceeds go to charity. Where the calories go, we aren't going to say.

    Things That Are Especially Fun in September

    September's warmer temperatures and sunnier days make it a good time to check out some of San Francisco's best beaches.

    September is blue whale and humpback whale season around San Francisco. Find out how, when and where in the San Francisco Whale Watching Guide.

     What to Expect from ​San Francisco Weather in September

    September brings clearer weather in most years, with warmer temperatures on average than in July and August. On a statistical basis, September is San Francisco's warmest month and one of its driest.

    In September, 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

    If you want to compare September weather to other months, check the Guide to San Francisco Weather and Climate.

    Use the weather averages to get an idea of what things may be like, but it might be different when you visit. A winter day could even be so warm you'll wish you packed your shorts.

    Averages are helpful for planning ahead, but don't count on your trip being "average." Check the San Francisco weather forecast before you leave home.

    With less fog and no rain, light layers will usually be plenty. An extra jacket or layer will feel nice in the evening. Rainfall is generally unlikely, but if your jacket is rainproof, it can do double duty.

    More San Francisco by Month

    If you're just starting to plan your trip and deciding when to go, you may want to know what San Francisco is like in other months.  You find that in these guides: 

    For a quiet time (although it may be rainy), try San Francisco in January or  San Francisco in February.

    March is the beginning of spring but you can also get spring weather (and crowds) in  San Francisco in April or San Francisco in May.

    Summer in San Francisco may not be what you think, especially if go to  San Francisco in June or in July, If you're looking for sunny days and lots of sunshine, try San Francisco in August.

    By fall, the skies will be clear and the crowds will be gone. In fact, the best times to visit may be San Francisco in September or San Francisco in October.

    Holiday...MORE festivities make the end of the year a good time to go to San Francisco in November or San Francisco in December.
