These areas have two distinct rainy seasons associated
with the northward and southward movement of the
ITCZ. Rainfall averages over 120 inches annually in
some areas. Throughout the rest of the year,
precipitation remains plentiful because of the influx of
maritime air from the west. There are no significant
mountains in the region to prevent this maritime air
from migrating inland. Temperatures are moderate year
round.
Southeast Coastal Region
The southeast coastal region has a humid
subtropical climate. This region has rainfall all year (45
inches on the average) and temperatures remain
generally moderate all year, ranging from an average
maximum of 72°F in winter (July) to 89°F in summer
(January).
Southeastern Interior Region
This region has a wet-and-dry type of maritime
climate; however, it is considered temperate because of
the lower temperatures common to the higher elevation.
AUSTRALIA AND NEW ZEALAND WEATHER
Australia has a generally mild climate with cool
winters in the south and warm winters in the north.
Summers are warm along the coasts and generally hot
in the interior. Freezing temperatures are infrequent.
Australias climatic zones are relatively uncomplicated
due to the lack of high mountain ranges.
The northern third of Australia is located within the
tropical zone. The region has a rainy season that runs
from January to April. Annual precipitation is greatest
(nearly 100 inches) in the extreme north and tapers off
to the south and inland toward the semiarid interior. The
interior, along the Tropic of Capricorn, is very hot and
dry
in
the
summer
with
average
maximum
temperatures at or above 90°F. In the winter, average
maximum temperatures in some areas drop to 68°F.
The southern two-thirds of Australia is under the
influence of the high-pressure belts of the Southern
Hemisphere as well as of the migratory lows found
farther
southward.
The
southwest
and
southern
portions of this region have rainy winters and
near-drought conditions in the summer similar to the
Mediterranean climate. Temperatures average 80°F in
January and 55°F in July. The climate of the southeast
corner is very similar to the southwest region except it
experiences
a
shorter
winter
and
less
annual
precipitation.
New Zealand is located southeast of Australia. It is
a very narrow country with a southwest to northeast
orientation and is exposed to the prevailing westerlies.
Therefore, the climate is moderate and predominantly
maritime
with
moderate
precipitation
occurring
throughout the year. The northern part of New Zealand
has a subtropical climate; however, winter frost and
occasional snow can occur at locations farther south in
highland areas. Fog is often widespread and very
persistent over much of the country in advance of
approaching frontal systems. Precipitation averages 49
inches in the northern half of the country and up to 170
inches in the southern half. Temperatures range from an
annual average of 59°F in the north and 55°F in the
central region to 50°F in the south.
