What to Expect from San Francisco in April
Most years, winter rains end by April. In an "El Nino" year, ocean currents bring California more rain than usual, and you can get wet until the middle of the month or later.
Nevertheless, April is San Francisco's sunniest month (on average).

What to Pack, What to Wear in April
April is often warm enough mid-day that you can get by with a couple of layers, but you'll need a bit more for evenings. It might seem a little early in the year for this, but April often has the most sunny days and a hat may be welcome.
San Francisco April Events
- San Francisco International Film Festival: This film fest features films you might never see anywhere else.
- Cherry Blossom Festival: Held in Japantown, it celebrates Japanese culture.
- Opening Day on the Bay: It's like a big parade, but on the water instead of land, with yachts of all sizes decorated for the event.
Especially Fun in April
April is gray whale season around San Francisco. Find out how, when and where in the San Francisco Whale Watching Guide.
Major League Baseball season runs from March through early October and San Francisco has one of the prettiest stadiums around. If the San Francisco Giants are playing at home, watching a game is fun way to spend a few hours. We like afternoon games better than night because it's warmer.
Averages and Reality
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.
