New York is a state in the Mid-Atlantic and Northeastern regions of the United States and is the nation's third most populous. The state is bordered by New Jersey and Pennsylvania to the south, and Connecticut, Massachusetts and Vermont to the east. The state has a maritime border with Rhode Island east of Long Island, as well as an international border with the Canadian provinces of Ontario to the west, and Quebec to the north. New York is often referred to as New York State to distinguish it from New York City.

Located on a large natural harbor on the Atlantic coast of the Northeastern United States, the city consists of five boroughs: The Bronx, Brooklyn, Manhattan, Queens, and Staten Island. The city's 2007 estimated population exceeds 8.3 million people, and with a land area of 305 square miles (790 km 2 ), New York City is the most densely populated major city in the United States. The New York metropolitan area's population is also the nation's largest, estimated at 18.8 million people over 6,720 square miles (17,400 km 2 ). Furthermore, the Combined Statistical Area containing the Greater New York metropolitan area contained million people as of 2008 Census estimates, also the largest in the United States.

The region was inhabited by about 5,000 Lenape Native Americans at the time of its European discovery in 1524 by Giovanni da Verrazzano, an Italian explorer in the service of the French crown, who called it "Nouvelle Angoulême" (New Angoulême). European settlement began with the founding of a Dutch fur trading settlement, later called "Nieuw Amsterdam" (New Amsterdam), on the southern tip of Manhattan in Dutch colonial Director-General Peter Minuit purchased the island of Manhattan from the Lenape in 1626 for a value of 60 guilders (about $1000 in 2006); a legend, now disproved, says that Manhattan was purchased for $24 worth of glass beads.

In 1664, the English conquered the city and renamed it "New York" after the English Duke of York and Albany. At the end of the Second Anglo- Dutch War the Dutch gained control of Run (a much more valuable asset at the time) in exchange for the English controlling New Amsterdam (New York) in North America. By 1700, the Lenape population had diminished to 200. During the American Revolutionary War the area emerged as the theater for a series of major battles known as the New York Campaign. After the upper Manhattan Battle of Fort Washington in 1776 the city became the British military and political base of operations in North America, and a haven for Loyalist refugees, until military occupation ended in 1783.

A major fire during the occupation led to the destruction of about a quarter of the city. The assembly of the Congress of the Confederation made New York City the national capital shortly after the war: the Constitution of the United States was ratified and in 1789 the first President of the United States, George Washington, was inaugurated; the first United States Congress and the United States Supreme Court each assembled for the first time in 1789, and the United States Bill of Rights drafted, all at Federal Hall on Wall Street. By 1790, New York City had surpassed Philadelphia as the largest city in the United States.

Under the Köppen climate classification, New York City has a humid subtropical climate and enjoys an average of 234 sunshine days annually. It's the northernmost major city in North America that features a humid subtropical climate using the 0 °C (American scientist standard) isotherm as criteria. Summers are typically hot and humid with average high temperatures of 79 – 84 °F (26 – 29 °C) and lows of 63 – 69 °F (17 – 21 °C), however temperatures exceed 90 °F (32 °C) on average of 16 – 19 days each summer and can exceed 100 °F (38 °C) every 4–6 years.

Winters are cold, and prevailing wind patterns that blow offshore somewhat minimizes the influence of the Atlantic Ocean. Yet, the Atlantic Ocean keeps the city warmer in the winter than inland North American cities located at similar latitudes such as Chicago, Pittsburgh and Cincinnati. The average temperature in January, New York City's coldest month, is 32 °F (0 °C). However temperatures in winter could for few days be as low as 10s to 20s °F (−12 to −6 °C)and for a few days be as high as 50s or 60s °F(~10–15 °C).

Spring and autumn are erratic, and could range from chilly to warm, although they are usually pleasantly mild with low humidity. New York City receives 49.7 inches (1,260 mm) of precipitation annually, which is fairly spread throughout the year. Average winter snowfall is about 24.4 inches (62 cm), but this often varies considerably from year to year, and snow cover usually remains very short. Hurricanes and tropical storms are rare in the New York area, but are not unheard of and always have the potential to strike the area.

Geography New York City is located in the northeastern United States, in southeastern New York State, approximately halfway between Washington, D.C. and Boston. The location at the mouth of the Hudson River, which feeds into a naturally sheltered harbor and then into the Atlantic Ocean, has helped the city grow in significance as a trading city. Much of New York is built on the three islands of Manhattan, Staten Island, and Long Island, making land scarce and encouraging a high population density.

The Hudson River flows through the Hudson Valley into New York Bay. Between New York City and Troy, New York, the river is an estuary. The Hudson separates the city from New Jersey. The East River, actually a tidal strait, flows from Long Island Sound and separates the Bronx and Manhattan from Long Island. The Harlem River, another tidal strait between the East and Hudson Rivers, separates Manhattan from the Bronx. The city's land has been altered considerably by human intervention, with substantial land reclamation along the waterfronts since Dutch colonial times. Reclamation is most notable in Lower Manhattan, with developments such as Battery Park City in the 1970s and 1980s.

A lot can be said about this wonderful city, there is only part in this presentation.
