What the numbers don't tell you
April is mostly dry and mild, with afternoons around 18 °C, the Cherry Blossom Festival in Japantown across two weekends in mid-April, baseball at Oracle Park and Easter crowds. Fog is still infrequent. Afternoons in the Mission can be warm while the Golden Gate stays cool. Rain falls on about five days.
The San Francisco International Film Festival runs in April. Hotel rates rise over Easter and the festival weekends, then ease. Alcatraz bookings should be made two weeks ahead. The wildflowers at Point Reyes and on Mount Diablo peak. The coastal trail from Lands End to the bridge is at its greenest. For Bay to Breakers and Memorial Day, see May.
