Long Island Info

Long Island has a climate that is very similar to other coastal areas of the Northeastern United States; it has warm, humid summers and cold winters, but the Atlantic Ocean helps bring afternoon sea breezes that temper the heat in the warmer months and limit the frequency and severity of thunderstorms. In the wintertime, temperatures are warmer than areas further inland (especially in the night and early morning hours), sometimes causing a snowstorm further inland to fall as rain on the island. However, measurable snow falls every winter, and in many winters one or more intense storms called nor’easters produce blizzard conditions with snowfalls of 1-2 feet and near-hurricane force winds.

Temperatures in Nassau and Suffolk are similar. The winter average for Nassau is 33.7 degrees Fahrenheit, compared to a summer average of 72.7 degrees. In Suffolk, the winter average is 32.4 and summer average is 71.9 degrees.

The Nassau area receives about 45 inches of rain, compared to 42 inches for Suffolk. Snow falls at about 26.9 inches per year in Nassau and 30 inches for Suffolk.

Long Island Geography
To the north of the island is Long Island Sound, which separates it from the coast of Connecticut and Rhode Island. To the south are the Great South Bay, South Oyster Bay, and Jamaica Bay, which are actually lagoons, protected from the Atlantic Ocean by a string of narrow barrier islands, most notably Fire Island. The island separates into two forks at the eastern end, known as the North Fork and South Fork.

Long Island is interesting because it is geographically part of the Mid-Atlantic, however many towns and hamlets along the island’s north shore and in eastern Suffolk County, such as Oyster Bay, Port Jefferson and Sag Harbor seem to resemble New England towns, while many of the towns and hamlets along the south shore, such as Long Beach, Valley Stream, and Babylon seem to resemble Mid-Atlantic coastal communities, especially those on the shore between New Jersey and Virginia.

Long Island can be considered the geographical border between the Mid-Atlantic and New England.

The island’s tallest point is Jayne’s Hill near Melville, with an elevation of 400.9 feet (122.2 m) above sea level. The island is separated from the mainland by the East River – actually not a river but both a tidal strait and a tidal estuary.

Long Island is an island located in the southeast part of the U.S. state of New York, just east of Manhattan. Stretching northeast into the Atlantic Ocean, Long Island contains four counties, two of which are boroughs of New York City (Queens and Brooklyn), and two of which are mainly suburban (Nassau and Suffolk). The term “Long Island” often refers only to Nassau and Suffolk counties in order to differentiate them from New York City, though all four counties on the island are part of the New York metropolitan area.

As of the 2010 census, Long Island had a population of 7,568,304,  making it the most populated island in any U.S. state or territory. It is also the 17th most populous island in the world, ahead of Ireland, Jamaica and the Japanese island of Hokkaidō. Its population density is 5,402 inhabitants per square mile (2,086 /km²). If it were a state, Long Island would rank 13th in population (after Virginia) and first in population density.

Both the longest  and the largest island in the contiguous United States, Long Island extends 118 miles (190 km) eastward from New York Harbor to Montauk Point, and has a maximum north-to-south expanse of 23 miles (37 km) between the northern Long Island Sound coast and the southern Atlantic coast. With a land area of 1,401 square miles (3,629 km²), Long Island is the 11th largest island in the United States and the 148th largest island in the world — larger than the 1,214 square miles (3,140 km²) of the smallest state, Rhode Island.

Two of New York City’s major airports, LaGuardia Airport and JFK International Airport, are located on Long Island, in Queens. Nine bridges and 13 tunnels (including railway tunnels) connect Brooklyn and Queens (and thus Long Island) to the three other boroughs of New York City. Ferries connect Suffolk County northward across Long Island Sound to the state of Connecticut.
