Excellent records of temperature and rainfall are available for the city of Sacramento. city may in a climatological sense be called the most representative city of the great valley. San Francisco, Sacramento, and Stockton form as it were the three central points of the bay and valley district. It will be noticed that the mean annual temperatures are respectively about 56, 60, and 60%. In other words the valley cities have a mean annual temperature about 4 higher than the coast city has. In January the mean temperature of the interior cities is nearly 4 below that of San Francisco. In March it is slightly above. In April nearly 4° above, which increase continues until October. During July there is a difference of nearly 15°. While the annual rainfall at San Francisco is 23 inches, that at Sacramento is 19.21 inches, and at Stockton 15.54 inches. There is thus a gradual decrease in the rainfall from the coast inland. December is the month of heaviest rainfall at all stations and August the month of least precipitation. With regard to the seasonal rainfall it may be stated that years in which the rainfall is well distributed, particularly where good rains fall in March and April, are years of large wheat yields.
