Why Does San Francisco Experience So Much Fog In the Summertime?

When warm, humid air from the Pacific Ocean moves over the cooler water of San Francisco Bay it condenses, producing advection fog.

This is the type of fog San Francisco experiences in the summer months, keeping the city cool, at least until it burns off around midday.

San Francisco’s climate is characteristic of the cool-summer Mediterranean climate of California’s coast with mild, wet winters and cool, dry summers.

Six U.S. state capitals lie west of Los Angeles, California: Honolulu, Hawaii; Juneau, Alaska; Salem, Oregon; Olympia, Washington; Sacramento, California; and Carson City, Nevada.
