New York City Weather in September

Planning a trip to New York City in September? Here's what the weather is really like as the city finally shakes off summer — and why a lot of travelers call it one of the best months of the year to visit.
September is when NYC exhales. Highs start the month in the 80s°F and slide into the low 70s by the end, lows drop into the 50s on cool late-month nights, and the humidity that defined July and August finally starts pulling back. Rain averages 8–10 days, mostly lighter than summer's severe thunderstorm pattern.
The main thing worth knowing: September sits inside peak Atlantic hurricane season. Direct hits on NYC are rare, but decaying tropical systems can occasionally bring a couple of days of heavy rain or travel delays — worth checking the forecast closer to your trip, not worth changing your plans over. Otherwise, September is genuinely one of the most comfortable, alive months in the city. Meteorologist Ian Schwartz breaks down what to expect.
