The climate of Central Valley (California - United States of America)
Central Valley is a valley which stretches almost the entire length of the state of California. The valley consists of two parts: Sacramento Valley and San Joaquin Valley. San Joaquin Valley consists of the southern part of Central Valley. This part of the valley is mainly used for agriculture. Among several large cities in this region are: Stockton, Modesto and Fresno. Sacramento Valley consists of the northern part of Central Valley. On this side of the Sacramento Dam the main source of income is also agriculture. Mainly fruit trees and walnut trees are cultivated here. The largest cities in this area are Redding, Sacramento and Davis. Because Central Valley is completely surrounded by mountains there is a high chance of smog in this region.
The northern part of Central Valley has a warm Mediterranean climate the climate in the southern part, in the Fresno region is dry enough to be classified as a Mediterranean Sea climate or even a desert climate in the regions southeast from Bakersfield. Summers here are hot and dry, winters are cool and wet. During the summer daytime temperatures may rise up to 32 degrees Celsius (89.6 degrees Fahrenheit). During heat waves temperatures may even rise up to 46 degrees Celsius (115 degrees Fahrenheit). The rainy season is during early spring. During this period heavy storms and floods are not uncommon. These phenomena mainly occur in the southern part of the San Joaquin Valley and to a lesser degree in Sacramento Valley. Precipitation figures are higher in the northern part of the valley than in the southern part. During the winter subzero temperatures are not uncommon. However, snowfall is uncommon. Central Valley is often shrouded in mist which is known here as Tule Mist.

More climate information
Climate figures are very useful but don’t present a general impression of the climate and the eventual weather circumstances within a certain period. The figures don’t always reflect the chance of wintry weather, extreme heat or hurricanes. That is why we offer useful extra climate information for each month of the year:
