The winter season in Davis is the rainy season. Weather fronts from the Pacific Ocean bring winter
storms into Davis. These storms can last up to several days or even a week. However, winter days
can also be sunny and mild, with daytime temperatures in the 60's and 70's F. Fog often appears
in winter, particularly in evening, night, and early morning. Fog develops in cold, calm air when
the soil below is moist, such as after a rainfall. The fog can become so dense that it makes driving
difficult. Winter fog, also called Tule Fog, is characteristic of the California central valley.
Winter
temperatures on the coldest days range from several degrees below freezing to the 30's and 40's
F. Weather reporters advise listeners to move their potted plants indoors and cover their vunerable
outdoor plants to avoid frost damage. Frost can also form on lawns during early morning hours.
In December 1998, there was a prolonged period of very cold weather which froze plants and
caused crop damage in agricultural fields.
