December 2019 felt like a weather roller coaster in New York City. Highs ranged from a relatively balmy 58°F to a frigid 25°F. But in the end, these extremes nearly balanced each other out. The city’s mean temperature for the month was 38.3°F, which is only 0.8°F above average.
In terms of precipitation, December was a month for the record books. The city received 7.09 inches of rain in Central Park, making it the fifth wettest December on record. It is also interesting to note that two different days produced rainfall totals greater than one inch. Snowfall, however, was below average. Only 2.5 inches was reported in Central Park. New York City, on average, sees 4 inches of rain and 4.8 inches of snow in December.
