San Francisco, California Weather in March

March: cool, changeable days

San Francisco feels mild in March, but the air can be damp and the sky often cloudy. Rain comes and goes, so outdoor plans work best when you can shift them around. Walk through Golden Gate Park or explore the Ferry Building on clearer days; save indoor stops for showers.

The chill is easier to notice by the water, especially on the Golden Gate Bridge. Bring a windproof layer for that walk, and don't count on a long, sunny beach afternoon. March is still a good month for city sights without summer's heat.

Parade and spring events

The St. Patrick's Day Parade brings music and crowds to downtown San Francisco in March. It's a fun pick if you enjoy a lively street event, but expect busy sidewalks along the parade route. The date can vary, so check the year's schedule before you go.

Cherry blossoms may appear around late March in Japantown, though bloom times depend on the weather. If you're travelling with kids, the parade offers an easy day out; Japantown is a quieter option for a stroll and a bowl of ramen.

Crowds and costs

March is generally calmer than the busy summer season, and hotel prices are often less steep than in peak months. The St. Patrick's Day Parade is an exception: downtown gets crowded around the event. Spring break can also bring more families, depending on the week.

For a practical local tip, take the Muni bus to the Golden Gate Bridge's south end rather than walking all the way from Fisherman's Wharf. You'll save time for the bridge itself, where wind and passing showers can make a long approach feel less pleasant.
