The Climate of New Jersey New Jersey is located about halfway
between the Equator and the North Pole, on the eastern coast of
the United States. Its geographic location results in the State
being influenced by wet, dry, hot, and cold airstreams, making
for daily weather that is highly variable. The Garden State is
166 miles long from north to south, and its greatest width is
about 65 miles. While this may not seem too large, there is a
marked difference in climate between Cape May in the south and
the Kittatinny Mountains of northwestern New Jersey. The
dominant feature of the atmospheric circulation over North
America, including New Jersey, is the broad, undulating flow
from west to east across the middle latitudes of the continent.
These "prevailing westerlies" shift north and south and vary in
strength during the course of the year, exerting a major
influence on the weather throughout the State. Some general
