STATEN ISLAND, N.Y. — The forecast for a particularly warm September in New York is no more.

The latest monthly weather outlooks issued by the National Weather Service’s Climate Prediction Center reveal a dramatic shift in the forecast.

According to the temperature outlook issued on Aug. 31, the entire East Coast now has equal chances of experiencing above-average or below-average temperatures over the course of the month ahead.

Previously, the Aug. 21 outlook claimed that September would generally bring warmer temperatures to New York. This initial forecast predicted a 50% to 60% likelihood of above-normal temperatures reigning supreme across much of the state in September.

This now-outdated forecast aligned with AccuWeather’s fall forecast, which called for a delayed transition to fall weather and the probability of lingering heat on the East Coast.

With this latest forecast now suggesting a somewhat typical September, New York residents should expect daily highs in the 70s as the fall begins to settle in.

The mean high temperature in the Central Park area of the city in September is 76.2 degrees, as indicated by National Oceanic and Atmospheric Administration data from 1991 to 2020. Meanwhile, the mean average temperature for the month is 69.2 degrees.
