San Francisco, California Weather in April

April feels mild

April brings spring weather to San Francisco. Afternoons reach about 17°C, while mornings and evenings feel cool, around 8°C. Rain is lighter than in March, with showers on about five days, and you'll often get sunny breaks between clouds.

It's a good month for walking the Embarcadero, exploring Golden Gate Park or taking in the views from Lands End. The Golden Gate Bridge can feel chilly and windy, so don't count on a long, comfortable stroll there every day. Families who like outdoor days will find plenty to do between showers.

Festivals and spring breaks

The Northern California Cherry Blossom Festival usually takes place in Japantown in April. Expect Japanese cultural performances, food stalls and crowds around the Peace Plaza. The San Francisco International Film Festival also often runs in April, though its dates vary.

School spring breaks can bring more visitors, especially to Fisherman's Wharf and family attractions. Still, April is generally calmer and less expensive than the busy summer months. It's a useful middle ground if you want city sights without peak-season crowds.

A good time to explore

April's mild afternoons suit a walk through Chinatown, a ride on a cable car or a picnic in the Presidio. Showers can interrupt outdoor plans, so keep a museum or a meal in North Beach in mind for a wet spell. May is drier and warmer, but April already offers long days and a good amount of sunshine.

For a practical local tip, take the N Judah to Ocean Beach rather than relying on a sunny forecast. The coast can feel much cooler than downtown, and the train makes it easy to head back if the wind picks up.
