December 2012 was unusually warm and wet in New York City. With nineteen out of thirty-one days posting warmer than normal readings, the city’s average monthly temperature reached 41.5°F, which is 3.5°F above normal.
On the precipitation side of things, the city collected 4.80 inches of rain, which is 0.8 inches above average. This is only the third time this year that NYC received normal to above normal monthly rainfall. In terms of snow this December, we saw 0.4 inches accumulate in Central Park – all of which fell as part of a wintry mix during the nor’easter on the day after Christmas. This meager snowfall total is 4.4 inches below the city’s long-term norm for the month.
