('''Dfa''').<ref name="auto">{{cite web|url=https://upload.wikimedia.org/wikipedia/commons/b/bb/Koppen_World_Map_%28retouched_version%29.png|title=World Map of Köppen-Geiger climate classification|last1=Peel|first1=M.C.|last2=Finlayson|first2=B.L.|publisher=The University of Melbourne |archive-url=https://web.archive.org/web/20150113015116/http://upload.wikimedia.org/wikipedia/commons/b/bb/Koppen_World_Map_%28retouched_version%29.png|archive-date=January 13, 2015|url-status=dead|access-date=27 June 2020}}</ref> The city experiences moderately cold, somewhat wet and snowy winters; and hot, humid summers with plentiful rainfall all year round. As it is more geographically southern, it is usually warmer in winter than in [[Upstate New York]]. Also, New York's enormous population, human activity, and vast amounts of large buildings and streets, which absorb sunlight during the day, contribute significantly to the [[urban heat island effect]]. Were it not for this phenomenon, its climate would probably be within the humid continental temperature range.


Meteorological records have been kept at [[Central Park]] since 1821, although the station was relocated to a different part of the park on January 1, 1920.<ref>{{cite web|url=https://www.ncdc.noaa.gov/cdo-web/datasets/GHCND/stations/GHCND:USW00094728/detail|title=Station Data Inventory, Access & History|publisher=NOAA|access-date=27 June 2020}}</ref> There are also other weather stations in the area including one at [[LaGuardia Airport]], beginning in 1940, and at [[JFK Airport]], beginning in 1948.

The highest temperature ever observed in Central Park is {{Convert|106|F|C}} on July 9, 1936, and the lowest is {{Convert|-15|F|C}} on February 9, 1934. The lowest daily maximum is {{Convert|2|F|C}} on December 30, 1917.

The city can be prone to extremes. [[Snowfall]] is an infrequent occurrence in the city, on average occurring on only 12 days per year, though it can be heavy when it occurs.

According to the Köppen climate classification, the climate of New York City is humid subtropical (Cfa), with parts of the city transitioning into a humid continental climate. (Dfa).[1] The city experiences moderately cold, somewhat wet and snowy winters; and hot, humid summers with plentiful rainfall all year round. As it is more geographically southern, it is usually warmer in winter than in Upstate New York. Also, New York's enormous population, human activity, and vast amounts of large buildings and streets, which absorb sunlight during the day, contribute significantly to the urban heat island effect. Were it not for this phenomenon, its climate would probably be within the humid continental temperature range.

Meteorological records have been kept at Central Park since 1821, although the station was relocated to a different part of the park on January 1, 1920.[2] There are also other weather stations in the area including one at LaGuardia Airport, beginning in 1940, and at JFK Airport, beginning in 1948. However, due to Central Park's long records and central location, it is often considered the main station for the city. Hence, all records unless otherwise stated will be for this station.

The highest temperature ever observed in Central Park is 106 °F (41 °C) on July 9, 1936 - although LaGuardia reported 107 °F (42 °C) on July 3, 1966, and the lowest is −15 °F (−26 °C) on February 9, 1934. The lowest daily maximum is 2 °F (−17 °C) on December 30, 1917. The highest daily minimum at Central Park is 87 °F (31 °C) on July 2, 1903.[3]

The city can be prone to extremes. Snowfall averages 29.8 in (75.7 cm) per year but is highly variable between winter seasons.[4] The city can also be prone to strong winds, being a coastal location it is exposed to the Atlantic. This can be especially pronounced during the autumn and winter months, with a gust of 78 miles per hour (126 km/h) being reported on December 2, 1974.[5] Governors Island, Manhattan, in New York Harbor, is planned to host a US$1 billion research and education center poised to make New York City the global leader in addressing the climate crisis.[6]

Classifications

Union Square in autumn

New York City falls under different climate types depending on the climate classification system used. However, the Köppen climate classification system is the most widely used climate classification scheme, in which New York City falls under the humid subtropical zone.

New York City Climate according to major climate systems
Climatic scheme Initials Description
Köppen system[1] Cfa Humid subtropical climate
Trewartha system[7] Do Temperate oceanic climate
Alisov system[8] — Temperate climate
Strahler system[9] — Moist continental climate
Thornthwaite system[10]
C2 B'1
 Moist subhumid mesothermal climate
Neef system[11] — East-side temperate climate

In the Holdridge life zones system, having a mean annual biotemperature above 53.6 °F (12 °C) and mean annual precipitation above 39.4 inches (1,000 mm), New York City features a warm temperate moist forest climate.[12] By the Trewartha classification, the city is defined as having an oceanic climate (Do).[13][14] Annually, the city averages 234 days with at least some sunshine.[15] The USDA plant hardiness zones are 7a and 7b. Most of the city is found in 7b, with forested areas and parks being in 7a, as shown in Staten Island and suburban areas. The city also has some small densely populated areas in 8a, like around Laguardia airport.[16]

Temperature

The city's regime of temperature features large seasonal swings, with four distinct seasons. However, due to its proximity to the Atlantic Ocean, these swings are less significant than areas further inland. The Atlantic serves as a moderator of the temperature meaning the city is milder than areas inland during the winter and cooler during the summer. Although, being on the east coast, this effect is less pronounced. All extremes are for the Central Park station.

Averages

In an average year, the temperature will usually be between 8 °F (−13 °C) and 97 °F (36 °C) with temperatures greatly exceeding these values being uncommon. Temperatures above 100 °F (38 °C) and below 0 °F (−18 °C) are very rare, with the last occurrences being July 18, 2012 and February 14, 2016, respectively.[17]

Snowfall

Other phenomena

Sunshine, UV and daylight

The city generally experiences sunny conditions. As a result of New York City's latitude, 40°42′46″N 74°00′22″W / 40.712740°N 74.005974°W / 40.712740; -74.005974, it is not subject to the extremes of daylight that places much farther north see.[28] However, it is far north enough for there to be a moderate change of possible daylight hours throughout the year.[29]

Wind

The wind is seldom strong in New York City but can occasionally be noticeable. This is especially true in the autumn and winter seasons when extratropical depressions often bring strong winds. The strongest gust in Central Park, of 78 miles per hour (126 km/h), occurred on December 2, 1974, however, a station at The Battery reported a gust of 113 miles per hour (182 km/h) on October 14, 1954.[31] However, tropical storms can sometimes affect the area, although they are infrequent and usually weak. Most recently Hurricane Sandy struck the city on October 29, 2012, causing billions of dollars in damage. It resulted in loss of power, severe flooding and many residents being displaced.[32]

Climate change

Main article: Climate change in New York City
The Queens–Midtown Tunnel is seen flooded in the aftermath of Hurricane Sandy.
Queens–Midtown Tunnel after flooding caused by Hurricane Sandy on October 29, 2012. Climate change means events like this will become more likely.

Being a coastal city, New York City is expected to experience significant effects from rising sea levels. Predictions that the sea level will rise by as much as 6 feet (1.8 m) by 2100 have prompted the city's mayor to invest $10 billion into keeping the city safe.[33] The city is also expected to become more susceptible to storm surges and flooding, meaning events like Hurricane Sandy's impacts will become more likely in the future.

Temperature

The temperature in New York City has generally increased steadily of the last 150 years and this trend is expected to continue due to anthropogenic warming. By 2080, it is predicted that the climate of the city will be similar to northern Arkansas. The mean temperature has risen by 2.4 °F (1.3 °C) since the 1970s and this warming is expected to accelerate in the coming decades.[34][35]

Precipitation

Precipitation in the city has significantly increased since 2000; both rainfall and snowfall have risen, but snowfall has increased much more significantly. However, it is argued that such trends, being so recent, make it impossible to predict whether such increases will continue or become steadier.[36]
