San Diego's climate is characterized as a hot-summer Mediterranean type, featuring predominantly sunny, dry summers and cooler, wetter winters. However, the region is notably more arid than typical Mediterranean zones, with relatively dry winters. Official weather reporting for the city is based at San Diego International Airport, where the climate, along with most coastal areas, is classified as borderline semi-arid due to its particularly mild winters and cool summers.
This climate is notable for its general mildness and predictability, which contributes significantly to San Diego's reputation as a desirable year-round destination. The weather supports a consistent tourism industry and an active outdoor lifestyle for residents, making it a defining feature of the region's identity.
Recently, San Diego's weather has been in the news due to a series of unusual storm systems affecting the area. A second rainstorm has moved into the region, following significant wet weather from a previous system. Authorities have issued warnings about hazardous coastal conditions, and meteorologists are tracking rainfall totals across different neighborhoods.
The National Weather Service has indicated that the region is bracing for cooler temperatures, storms, and potential mountain snow. This active weather pattern represents a notable departure from the area's typically dry and sunny conditions during this period, drawing increased public and media attention.
