New York City may experience a warmer and wetter winter season as a rare and powerful Super El Niño is developing, according to AccuWeather Senior Meteorologist Carl Erickson and CNN Weather.
This intensified version of the El Niño phenomenon occurs when Pacific equatorial region temperatures surge above average, triggering a chain reaction that shifts global weather patterns. For the Northeast, this typically translates to warmer temperatures and increased precipitation, while the Southeast may see wetter and colder winters and the Midwest drier conditions.
Erickson indicated that warmth could persist through September, with cooler air making brief appearances in October. By late fall and winter, El Niño is expected to exert a greater influence on the overall weather. While some snow is possible by late October or November if a storm aligns with cold air, specific event predictions are premature.
Forecasts suggest a wetter season once winter fully establishes, with El Niño sometimes leading to elevated precipitation along the Atlantic Coast. New York City faces a 50% to 60% chance of experiencing higher-than-average precipitation between December and February. The probability of higher-than-average temperatures during the same period is approximately 40% to 50%.
This pattern could mean a winter of rain and sleet for New Yorkers rather than significant snowfall. The likelihood of these conditions increases if the pattern develops into a Super El Niño, which has about a 70% chance of occurring by October.
New York City has already seen a notably wet August, with over 8 inches of rain falling so far, marking the wettest August in five years. The last comparable rainfall occurred in 2021, when over 10 inches were recorded.
