Southern
California gets morning fogs which the sun soon burns away. The summer
mornings are cool along the coast, the afternoons hot but rarely humid.
Along
the coast the climate is generally mild, but inland temperatures can get
quite warm. As you move inland the terrain steepens and the temperature
rises. On
some days coastal and inland temperatures may differ by as much as 30
degrees.
Coastal
San
Diego’s
heat is
moderated
by ocean
breezes
but
occasional
Santa
Ana
winds
from the
desert
can heat
things
up
during
September
and
October.
An
average
of 10
inches
of rain
falls

in

Located
closer
to the
equator
than to
the
north
pole,
our
waters
are
almost
semi-tropical
and
possess
many
marine
organisms
with
close
relatives
from
farther
south.
Our
coastal
climate
is
characterized
as
Mediterranean
- that
is, with
mild
winters
and
temperate
summers,
which
encourages
the
occurrence
of
marine
flora
and
fauna
that are
transitional
between
true
tropical
and true
temperate.
