July 2019: Tenth Hottest July on Record for NYC

July is usually the warmest month on the calendar for New York City, but this year it was especially hot. In fact, it tied July 1949 as the city’s tenth warmest July on record.

In all, it produced 26 days with above-average readings, including ten days in the 90s. Four of those days came during a heatwave in the middle of the month when the air temperature reached 95°F and the humidity made it feel well above 100°F.

Overnight lows were also mostly warmer than normal throughout the month. On July 20, the mercury only fell to 82°F, setting a new record warm low temperature for the date. In the end, the city’s mean temperature for the month was 79.6°F, which is 3.1°F above average.

It is important to note that four of the city’s ten warmest Julys on record have now occurred since 2010. The warmest was July 1999, when the average temperature for the month was 81.4°F.

This July was also above average in terms of precipitation. With several intense thunderstorms rolling through the area, a total of 5.77 inches of rain was measured in Central Park. The city, on average, gets 4.60 inches of rain for the month.
