Weather Conditions

Bay view

In the San Diego Bay area, the prevailing winds and weather are tempered by the Pacific Ocean, with the result that summers are cool and winters warm in comparison with other places along the same general latitude.

A marked feature of the climate is the wide variation in temperature within short distances. In nearby valleys, daytimes are much warmer in summers, nights are noticeably cooler in winter, and freezing occurs much more frequently than in the city. Although records show unusually small daily temperature ranges, averaging only about 7.2° C between the highest and lowest readings, a few miles inland these ranges increase to 16.6° C or more.

Seventy-five percent of the rainfall occurs from November through March, but wide variations take place in monthly and seasonal totals.

As on the rest of the Pacific Coast, a dominant characteristic of spring and summer is the nighttime and early morning cloudiness. Usually during the fall and winter months, considerable fog is experienced along the coast, but the amount decreases with distance inland.

The following information, compiled from the records of the United States Weather Bureau Station at San Diego International Airport, was furnished by Environmental Data Service, Environmental Science Services Administration, the United States Department of Commerce. The National Weather Service maintains an office at San Diego International Airport; barometers may be compared there or by telephone.
