San Diego has a semi-arid coastal climate with mild, sunny weather year-round. At San Diego Lindbergh Field, the 1991-2020 reference averages range from a daily high of 66°F (19°C) in Dec to 77°F (25°C) in Aug. Monthly precipitation averages sum to 9.8 inches (249 mm) per year.
May Gray and June Gloom often keep coastal areas cool and overcast. Late summer is generally warm and dry, and Santa Ana winds can bring inland heat and fire danger. Most rain arrives with cool-season Pacific storms, but tropical moisture and summer thunderstorms can also produce heavy rain.
The Pacific Ocean moderates temperatures near San Diego's coast. Inland neighborhoods can be much hotter, especially during offshore wind events.
Local Planning Guide
San Diego's notable windows are late-spring marine-layer gloom, fall Santa Ana wind events, and winter Pacific storms.
Coastal, inland, and mountain zones differ sharply. Use radar for precipitation, temperature observations for heat, and visibility or satellite information for marine-layer clouds.
