Blog: "I wasn't on vacation! I got lost in the fog of San Francisco!"
The summer in San Francisco is... Wait! What summer!? The only thing I have seen during the whole -supposedly- summer is a thick layer of fog over my head.
"The coldest winter I ever spent was a summer in San Francisco". This saying is the coolest thing Mark Twain never said. It describes the SF summer perfectly. If you come to SF, you will hear people saying that they run the heater only four months of the year: January, February, July and August. In fact, some days of August, San Francisco gets colder than the city of Anchorage, Alaska, with less than 12ºC.
The summer fog is caused when the sun heats the Sacramento and San Joaquin valleys, which draws in the cool marine air from the Pacific Ocean. Often a low atmospheric pressure area is associated with the interior valleys and an area of high atmospheric pressure out in the ocean.
The high-pressure area is called the Pacific High. In the meantime, the ocean currents produce a rising of cooler water. The result is condensed ocean water that rises in a mist: fog. Now the changes in atmospheric pressure move in -- air from high-pressure areas on the coast moves toward low-pressure areas, producing wind and moving the fog inland.

Now is Setember; the summer has begun in San Francisco.
