Geography of New York City - wikipedia Geography of New York City Jump to : navigation , search Satellite image showing most of the five boroughs , portions of eastern New Jersey , and the main waterways around New York Harbor The geography of New York City is characterized by its coastal position at the meeting of the Hudson River and the Atlantic Ocean in a naturally sheltered harbor . The city 's geography , with its scarce availability of land , is a contributing factor in making it one of the most densely populated cities in the United States . Environmental issues are chiefly concerned with managing this density , which also explains why New York is among the most energy efficient and least automobile - dependent cities in the United States . The city 's climate is temperate .

It is located in the New York -- New Jersey Harbor Estuary , the centerpiece of which is the New York Harbor , whose deep waters and sheltered bays 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 western Long Island , making land scarce and encouraging a high population density . The Hudson River flows from the Hudson Valley into New York Bay , becoming a tidal estuary that separates the Bronx and Manhattan from Northern New Jersey . The Harlem River , another tidal strait between the East and Hudson Rivers , separates Manhattan from the Bronx . The boroughs of New York City straddle the border between two geologic provinces of eastern North America . Brooklyn and Queens , located on Long Island , are part of the eastern coastal plain . Long Island is a massive moraine which formed at the southern fringe of the Laurentide Ice Sheet during the last Ice Age . The Bronx and Manhattan lie on the eastern edge of the Newark Basin , a block of the Earth 's crust which sank downward during the disintegration of the supercontinent Pangaea during the Triassic period . The Palisades Sill on the New Jersey shore of the Hudson River exposes ancient , once - molten rock that filled the basin . Tough metamorphic rocks underlie much of Manhattan , providing solid support for its many skyscrapers . 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 modern developments like Battery Park City . Much of the natural variations in topography have been evened out , particularly in Manhattan . The West Side of Manhattan retains some hilliness , especially in Upper Manhattan , while the East Side has been considerably flattened . Duffy 's Hill in East Harlem is one notable exception to the East Side 's relatively level grade . The city 's land area is estimated to be 321 square miles ( 830 km ) . However , a more recent estimate calculates a total land area of 304.8 square miles ( 789.4 square kilometres ) . The highest natural point in the city is Todt Hill on Staten Island , which at 409.8 ft ( 124.9 m ) above sea level is the highest hill on the Eastern Seaboard south of Maine . The summit of the ridge is largely covered in woodlands as part of the Staten Island Greenbelt . Adjacent counties ( edit ) New York Westchester County Nassau County New Jersey Monmouth County Middlesex County Union County Hudson County Bergen County Boroughs ( edit ) Main articles : Borough ( New York City ) and Neighborhoods in New York City New York City comprises five boroughs , an unusual form of government used to administer the five constituent counties that make up the city . Throughout the boroughs there are hundreds of distinct neighborhoods , many with a definable history and character all their own . If the boroughs were each independent cities , four of the boroughs ( Brooklyn , Queens , Manhattan , and the Bronx ) would be among the ten most populous cities in the United States . The Bronx ( Bronx County , pop. 1,364,566 ) is New York City 's northernmost borough . It is the birthplace of rap and hip hop culture , the site of Yankee Stadium , and home to the largest cooperatively owned housing complex in the United States , Co-op City . Except for a small piece of Manhattan known as Marble Hill , the Bronx is the only section of the city that is part of the North American mainland . Brooklyn ( Kings County , pop. 2,511,408 ) is the city 's most populous borough and was an independent city until 1898 . Brooklyn is known for its cultural diversity , an independent art scene , distinct neighborhoods and a unique architectural heritage . The borough also features a long beachfront and Coney Island , famous as one of the earliest amusement grounds in the country . Manhattan ( New York County , pop. 1,606,275 ) is the most densely populated borough and home to most of the city 's skyscrapers . The borough contains the major business centers of the city and many cultural attractions . Manhattan is loosely divided into downtown , midtown , and uptown regions . Queens ( Queens County , pop. 2,256,576 ) is geographically the largest borough and the most ethnically diverse county in the United States . Historically a collection of small towns and villages founded by the Dutch , the borough today is mainly residential and middle class , with enclaves of above average income and wealth . It is the only large county in the United States where the median income among African - American households , about $52,000 a year , has surpassed that of Caucasian households . Queens is the site of Citi Field and its predecessor Shea Stadium , the home of the New York Mets , and annually hosts the US Tennis Open . Staten Island ( Richmond County , pop. 475,014 ) is the most suburban in character of the five boroughs . It is connected to Brooklyn by the Verrazano - Narrows Bridge and to Manhattan by the free Staten Island Ferry . Until 2001 the borough was home to the Fresh Kills Landfill , formerly the largest landfill in the world , which is now being reconstructed as one of the largest urban parks in the United States .

The region 's climate is vastly affected by its proximity to the Atlantic Ocean . New York City 's climate patterns are affected by the Atlantic multidecadal oscillation , a 70 - year - long warming and cooling cycle in the Atlantic that influences the frequency and severity of hurricanes and coastal storms . Unless otherwise stated , all figures below are cited from the Central Park station . Winters are typically cold . During the typical winter , there are 17 days where the temperature fails to rise above 32 ° F ( 0 ° C ) . Although there is an average 2.7 nights with a low at or below 10 ° F ( − 12 ° C ) , and the city is located in USDA Hardiness Zone 7 , indicating the coldest temperature of the year is typically in the 0 to 10 ° F ( − 18 to − 12 ° C ) range , temperatures reaching 0 ° F ( − 18 ° C ) are very uncommon , with the most recent occurrence being on February 14 , 2016 . New York winters sometimes feature several nor'easters that can paralyze the city with over a foot ( 30 cm ) of snow . However , variation in the climate also occasionally renders winter mild and almost snowless . Springs are mild , with high temperatures averaging in the 50s ° F ( 10 to 15 ° C ) in late March to the lower 80s ° F ( 26 -- 28 ° C ) in early June . The weather is unpredictable and can even bring relatively cool summers ( such as in 1992 ) as an occasional surprise , and snowstorms arriving as late as the second week in April ( significant snow after mid-March is fairly rare though ) . Thunderstorms are common in spring . Summers in New York are hot and humid , with temperatures reaching 90 ° F ( 32 ° C ) or higher on an average of 17 days per year ( with the average window for such readings being May 27 thru August 24 ) , although high temperatures above 100 ° F ( 38 ° C ) are rare , having last been seen July 18 , 2012 . Humidity levels are usually quite high in July and August . Thunderstorms are common in summer , and produce even the occasional tornado , although severe weather is more common west of the city in New Jersey because the city 's proximity to the ocean usually greatly weakens severe thunderstorms before they hit the city . Hurricanes are considered to be a major threat to the area ( and especially the Long Island suburbs ) . While infrequent , a direct hit could cause large loss of life and enormous property damage due to the high population in coastal areas , as proven by Hurricane Sandy in October 2012 . Autumns are comfortable in New York and similar to spring in temperature . However , the weather is notably unpredictable and travelers are advised to check forecasts and bring several layers of clothing in late fall and in the early spring months ( e.g. November , March , April ) as temperatures do fluctuate quickly at these times of year . Precipitation is plentiful and averages at 49.9 in ( 1,267 mm ) annually , with spring being the wettest season and February the driest month . However , the wettest year on record at Central Park , 1983 , with 80.56 in ( 2,046 mm ) of precipitation , as well as five other of the top 10 wettest years , occurred during the current 1981 -- 2010 normal period ; for all months except December , the median monthly precipitation is less than the official monthly normal precipitation . The driest year was 1965 with 26.09 in ( 663 mm ) of precipitation . Monthly precipitation has ranged from 0.02 in ( 0.5 mm ) in June 1949 to 18.95 in ( 481 mm ) in August 2011 . New York can have excessive days of rain or long stretches of dry weather . The most rainfall in 24 hours was 8.28 in ( 210.3 mm ) on September 23 , 1882 . Snow averages at 25.8 in ( 65.5 cm ) per season , but this figure increases rapidly in the suburbs to the north and west and decreases slightly towards the Long Island suburbs . The most snow in one calendar day was 27.3 in ( 69 cm ) on January 23 , 2016 , part of the city 's heaviest fall in a single storm at 27.5 in ( 70 cm ) on January 22 -- 23 , 2016 . With monthly snow records dating back to 1869 , the most snow in a single month was 36.9 in ( 94 cm ) in February 2010 , and the snowiest season is , by far , 1995 -- 96 with 75.6 in ( 192 cm ) . The least snowy season was 1972 -- 73 with 2.8 in ( 7.1 cm ) . The window for measurable ( ≥ 0.1 in or 0.25 cm ) snow is on average December 15 thru March 17 ; March snow occurs in the majority of seasons while April or November snow is typically only seen at most several times per decade . Nothing more than trace amounts has fallen in May , while several decades may pass between measurable snow events in October . Temperature records have been set as high as 106 ° F ( 41 ° C ) on July 9 , 1936 ( in Central Park ; LaGuardia Airport recorded a 107 ° F or 42 ° C reading on July 3 , 1966 ) and as low as − 15 ° F ( − 26 ° C ) on February 9 , 1934 . The record high daily minimum temperature was 84 ° F ( 29 ° C ) , most recently on July 22 , 2011 ( although LaGuardia Airport recorded a daily low of 86 ° F or 30 ° C as recently as July 19 , 2013 ) , while the record low daily maximum temperature was 2 ° F ( − 17 ° C ) on December 30 , 1917 . Over the course of a year , New York City averages 70 days with lows at or below freezing ; the average window for freezing temperatures is November 20 through March 29 , allowing a growing season of 235 days .

article : Environmental issues in New York City Central Park is nearly twice as big as the world 's second - smallest country , Monaco . Historically its reservoirs were important components of the city 's water supply . New York City plays an important role in the green policy agenda because of its size . Environmental groups make large efforts to help shape legislation in New York because they see the strategy as an efficient way to influence national programs . New York City 's economy is larger than Switzerland 's , a size that means the city has potential to set new de facto standards . Manufacturers are also attuned to the latest trends and needs in the city because the market is simply too big to ignore . Although cities like San Francisco or Portland , Oregon are most commonly associated with urban environmentalism in the United States , New York City 's unique urban footprint and extensive transportation systems make it more sustainable than most American cities .
