The table below shows that our temperatures are mild throughout the year.
It also shows the effects of the Pacific Ocean and of Microclimates
(elevation, exposure to ocean breezes, etc.) on the seasonal
temperature extremes. Both the average temperature and the temperature extremes
increase as you go further inland but they may also be effected by
the Microclimate of the area. For example, the temperature in Carlsbad
(near the coast) seldom exceeds 80°F during the summer and seldom drops
below 39°F during the winter, while eastern Escondido and Valley Center
usually experience a few days of temperatures around 100°F in the summer
and a few nights slightly below 32°F in the winter. Fallbrook, although further
inland than Escondido, may have slightly milder temperatures than Escondido because
of its exposure to ocean breezes.

Bernardo Temperature data is not available. The data shown are estimates

Few hot, muggy summer days occur anywhere in North San Diego County
because it seldom rains during the summertime. The warmer inland summer
afternoons are accompanied by low (30-65%) relative humidity. The afternoon
humidity is higher near the coast but the temperature is lower and
therefore, the outdoor weather usually remains comfortable throughout the
Average annual precipitation ranges from 9-16 inches (23-41cm) of rain per
year, mostly falling from early November through March.
Storms and Earth Quakes
Hurricanes- We very seldom have hurricanes (last
Recorded, deadly hurricane called a "typhoon" to hit So.
California was in 1939).
Storms- Hail storms and tornadoes are also extremely rare and we have
few windy or rainy days. We do have occasional Santa Ana conditions, usually
occurring during the months of October through February, where easterly
winds from the desert produce a few warm (sometimes hot) and windy days.
Earthquakes- We are located approximately 30 miles from the nearest
major Earthquake Fault. The epicenter of the last major earthquake to be felt here was
located near Guadalupe Victoria, Baja California, Mexico; approximately 150
miles southeast of North San Diego County. It was the 7.2 magnitude
earthquake that occurred on Easter Sunday, April 4, 2010. Although not in our area, it was the strongest earthquake felt here
during the 27 years we have lived here. It was also felt throughout most of So. California and as far away as
Phoenix, AZ and Las Vegas, NV. It caused very little damage to our area.
The USGS (United States Geological Survey) website in 2005,
recorded the last significant earth quake in the San Diego area occurred in 1894, its magnitude was 5.75.
The latest USGS records however do not list any San Diego area earthquakes in its list of
"Historic Worldwide Earthquakes".
Although we experience some infrequent, short-term air pollution (seldom
Air Quality is
nearly always "Good." Unlike some U.S. cities and other areas of Southern
California, we have very little smog.
The sun shines from approximately 68% of time possible on the coast to
approximately 77% inland. May and June are the months with the least amount
of sunshine. Morning overcast and afternoon sunshine is common along the
coast in the spring and early summer.
The growing seasons range from around 270 days inland to 365 days along the
