Marine Corps Air Station El Toro, California is
located in the southern section of an area known as
the "Los Angeles Basin". The air station is
screened on 3 sides by mountain barriers. Land in
the immediate vicinity of the station is cleared and
cultivated and under extensive urbanization.
The region in which the air station is located
enjoys one of the most equable climates in North
America. The summer begins in April and lasts
through October. Increased stability in the form of
haze, fog and stratus. The prevailing wind
direction is west at about 5 knots.
The dry easterly winds (Santa Ana) that
sometimes blow for several days at a time, bring
temperatures in the 90's, and at times over 100
degrees F. Since September 1949, this station has
recorded a total of 25 days which were under the
influence of the "Santa Ana" winds.
The "Santa Ana" wind that is experienced at
this station may occur in almost any month of the

winter phenomenon. The average rainfall is
approximately 12 inches and the major portion of it
usually falls during winter storms. Snow has been
observed at this station upon rare occasions and the
