COASTAL
San Diego’s coastal area enjoys a mild marine climate because the Pacific Ocean is comparatively warm. The winters are mild, the summers are cool, and the air seldom really dry, unless there is a Santa Anna wind from the east.
The average high temperature range: From 65 degrees during the winter to 77 degrees in the summer. It is rare to see temperatures in the 90. The lows range from 48 degrees in the winter to 66 degrees in the summer. There are a few days during the winter when highs only reach the upper 50s.
During May and June, a thick “marine layer” cloud cover keeps the air cool and damp within a few miles of the coast, but yields to bright cloudless sunshine about 5 and 15 miles inland. This fog layer quite often burns off by midday, bathing the coastal
areas with warm Southern California sunshine. This fog layer is referred to locally as May Grey and June Gloom.
The coast averages about 10 inches (250 mm) of precipitation annually, with only an average of three thunderstorms a year. From November to March, Coastal San Diego averages from 1 – 2 inches of rain per month, but it is rare to see rain between May and September.
COASTAL INLAND
The average high temps range from 69 degrees during the winter to 88 degrees in the summer, with temperatures occasionally reaching 90 °F (32 °C) or higher. Low temperatures average from 41 degrees in the winter to 64 degrees in the summer. Because temperatures rarely drop very far below 30°F (–1°C), this is fine citrus growing country.
