Weather
Mild, dry desert air mixes with a coastal breeze to deliver San Diego a daily average temperature of 21°C (70°F). Between May and October temperatures of 30°C (85°F) or higher are not uncommon, particularly in the inland areas. The city averages a mere 10 inches of rain and even during the coldest months of December and January, the mercury still climbs to a very civil 20°C (68°F).
