The climate of San Diego, California, is classified as a hot-summer Mediterranean climate (Köppen climate classification Csa). While the basic climate features hot, sunny, and dry summers, and cooler, wetter winters, San Diego is more arid than the typical Mediterranean climate and consists of relatively dry winters compared to other zones with this type of climate. The climate at San Diego International Airport, the location for official weather reports for San Diego, as well as the climate at most beach areas, straddles the border between BSh and BSk due to the mild winters and cool summers in these locations.
