DEMOGRAPHICS / CLIMATE
Long Island climate is similar to that of other Northeast coastal areas, with warm and humid summers and cold winters. However, the Atlantic Ocean brings cooling breezes in the warmer months. Winter temperatures tend to be warmer than those experienced further inland. Sometimes inland snow storms will fall as rain on Long Island. Measurable snow falls every winter. Long Island temperatures also vary from west to east, with the eastern section being the cooler side. The western section is closer to the mainland and more densely developed, holding “urban heat.” The less developed east side maintains a more natural environment and is more affected by oceanic winds.
