The climate of New Jersey
New Jersey State experiences a humid subtropical climate (Köppen Cfa, Cfb) in South Jersey, central and the northeast. The northwest portion has a humid continental climate (Köppen Dfa, Dfb) with cooler temperatures than the rest of the state. New Jersey lies on the eastern shore of the United States, halfway between the Equator and the North Pole. Delaware in the southwest, Pennsylvania in the west, New York in the north, and the Atlantic Ocean in the east and southeast share borders with the state. The distance from the Atlantic Ocean, and the prevailing westerly winds that flow from west to east influence the climate.
New Jersey, the Garden State, has an average elevation of 80 meters, with the highest elevation at High Point at 549 meters. There are five major geographical zones, with significant temperature differences between the south and the northwest. The Northern Zone covers one-fourth of the state and consists of highlands and valleys. The Central Zone runs from the Lower Hudson River to Trenton near the great bend of the Delaware River and experiences the heat island effect. Cold fronts in the highlands result in clouds when the rest of the state has clear skies. Pine Barrens with scrub pine and oak forests dominate the central south. The Southwest Zone has a maritime influence on the climate and lies between sea level and 30 meters above it. The Coastal Zone battles between continental and oceanic influences.
