San Diego Weather

If you’re a person who dislikes change or seasonal wardrobes, San Diego will enrapture you with its temperate weather, light rainfall, and daily sunshine. Year ’round, this coastal city creates an ideal climate for surfers, bicyclists, golfers, and every other outdoor enthusiast. Daylight temperatures average 70.5 degrees, with lows dipping to around 48 degrees in January, and highs as warm as 78 in August. Like any city, San Diego has its aberrant weather phenomena—a record low of 29 degrees in January 1949 and a searing 111 degrees in September 1963.

Yet you’ll rarely break a heat sweat or chatter your teeth here. Rain is minimal as well: While the average precipitation is heaviest in the year’s first three months, it doesn’t rise above 2.5 inches. Meteorologists, however, must consider local topography when making forecasts, as the area’s mountains, hills, and valleys scramble precipitation patterns. For instance, the neighborhood of Escondido, 20 miles inland and 660 feet above sea level, receives 50 percent more rainfall than San Diego’s beach communities.
