March is an excellent time to visit San Francisco, with smaller crowds than in summer. It's also an excellent time to get in a visit before the summer fog sets in.

March is when many schools take their spring breaks. If you are planning a trip during that time and want to avoid crowds, San Francisco is a good choice. It's not in the top destinations for college students, and families tend to go to Southern California, leaving the City by the Bay quieter and more laid back.

Rain often starts tapering off by March, but if precipitation happens, try these things to do on a rainy day in San Francisco.

What to Pack

Check the forecast for rain a few days before you go and consider a waterproof, hooded jacket or full-length raincoat if it's predicted.

San Francisco is a walking city with lots of hills, some of them steep enough to take your breath away. Pack comfortable, broken-in walking shoes for running around during the day.

You aren't likely to need your short shorts and flip-flops in San Francisco in March. Layers with sweaters are best this time of year. And no matter how much you love your skirts and dresses, pants and tights will keep your legs much warmer when a chilly wind starts blowing. San Francisco's coastal location and ocean breezes may make it feel a little cooler than what the thermometer leads you to think. Also pack a mid-weight, slightly warm jacket.
