Manhattan as we know it

According to 2006 U.S. Census Bureau estimates, there are 1,611,581 people, 738,644 households, and 302,105 families residing in Manhattan.GR2 As of the 2000 Census, the population density of New York County was 66,940.1/mi² (25,849.9/km²), the highest population density of any county in the United States.[88] In 1910, at the height of European immigration to New York, Manhattan's population density reached a peak of 120,250.299/mi² (46,428.9/km²). There were 798,144 housing units in 2000 at an average density of 34,756.7/mi² (13,421.8/km²).[1] Only 20.3% of Manhattan residents lived in owner-occupied housing, the second-lowest rate of all counties in the nation, behind The Bronx. Although located at about the same latitude as the much warmer European cities of Naples and Madrid, Manhattan has a humid continental climate (Köppen classification Dfa) resulting from prevailing wind patterns that bring cool air from the interior of the North American continent. The city's coastal position keeps temperatures relatively warmer than inland regions during winter, helping to moderate the amount of snow which averages 25 to 35 inches (63.5 to 88.9 cm) each year.[59] New York City has a frost-free period lasting an average of 220 days between seasonal freezes.[59] Spring and Fall in New York City are mild, while summer is very warm and humid, with temperatures of 90 °F (32 °C) or higher recorded from 18 to 25 days on average during the season.[59] The city's longterm 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 in the region.[60]

Temperature records have been set as high as 106 °F (41 °C) on July 9, 1936 and as low as -15 °F (-26 °C) on February 9, 1934. These temperatures are not common and have not been matched or surpassed in more than seven decades. Most recently, temperatures have hit 100 degrees as recently as July 2005 and 103 degrees in August 2006, and dropped to just 1 above zero as recently as January 2004. New York can have excessive days of rain or long stretches of dry weather.

Summer evening temperatures are exacerbated by the urban heat island effect which causes heat absorbed during the day to be radiated back at night, raising temperatures by as much as 7 °F (4 °C) when winds are slow.
