Tule Fog

Tule Fog

We had cold rain over the weekend, and right on cue, our first tule fog of the season showed up this morning.

Tule Fog, from Wikipedia:

Tule fog 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 fall 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.

For those who haven’t experienced it, tule fog is a heavy, wet fog that blankets the low lying areas of Northern California this time of year. It’s responsible for many traffic-related deaths each year, and it poses a definite hazard to bike commuters. For those who venture out into tule fog, bright lights and extreme caution are a must. Because it’s such a heavy, wet fog, rain gear’s not a bad idea either.

As much as it sounds like a negative thing, I have to admit to enjoying the quiet and solitude associated with riding through a thick blanket of tule fog.
