Why Fog?
Fog forms off the coast of San Francisco. Air in the coastal valleys of the Bay Area and the Central Valley of California heats up during the day. Learn Why at the Exploratorium website: www.exploratorium.edu/wsw/projects/fog/index.html

ABout Fog
Fog is a cloud in contact with the ground. Stratus clouds are usually the only clouds that touch the ground. Fog differs from other clouds only in that fog touches the surface of the Earth. The same cloud that is not fog on lower ground may be fog where it contacts higher ground such as hilltops or mountain ridges. Fog is distinct from mist only in its density. Fog is defined as cloud which reduces visibility to less than 1 km, whereas mist is that which reduces visibility to less than 2 km.

The foggiest place in the world is the Grand Banks off the island of Newfoundland, Canada. Fog is frequent there as the Grand Banks is the meeting place of the cold Labrador Current from the north and the much warmer Gulf Stream from the south. The foggiest land areas in the world are Point Reyes, California, and Argentia, Newfoundland and Labrador, both with over 200 foggy days a year.

Tule fog
From Wikipedia:
"Tule fog (IPA: /'tu?li/) is a thick ground fog that settles in the San Joaquin Valley and Sacramento Valley areas of California's Great Central Valley. Tule fog forms during the late autumn and winter (California's rainy season) after the first significant rainfall. The official time frame for tule fog to form is from November 1 to March 31. This phenomenon is named after the tule grass wetlands (tulares) of the Central Valley. Accidents caused by the tule fog are the leading cause of weather-related casualties in California."

San Francisco has many different types of fog. There is the tule fog that hunkers in the winter. There is the summer fog that flows over the ocean foothills dry ice. There is the definitely fall fog that comes in the slot and there is the fog as percieved by downtown San Francisco, omnipresent.

Fog makes San Francisco and San Francisco Bay a photographers dream.
