April is a perfect time to explore San Francisco! The average high temperature will be around 63 F. On a few of the warmer afternoons, you can expect temperatures to reach at least 75 F. April becomes a little warmer and less foggy in San Francisco.
April is the month when San Francisco is found abundant with spring blooms. This is actually a transition period between wet and dry season, when the weather is particularly amiable: nearly cloudless, neither too moist, nor too dry, and with cool Pacific sea breezes being replaced by dry offshore winds.
City Guides always recommends wearing layers all year round when visiting San Francisco. The weather may change from cool to warm depending on what part of the City you are visiting. The wind also can be factor. It is also important to always wear a good pair of walking shoes.
