Intro

What’s the weather like in New York in September?

New York’s location on the east coast of the United States means the city has a continental climate, with temperatures cooling in September as summer turns into autumn. Although you’ll get plenty of sunshine, the cooler weather’s great if you want to explore the city.

Climatic influences

New York has four distinct seasons, and you might find September more comfortable compared to the heat of summer. The Appalachian Mountains keep things from cooling too much, while offshore winds mean the Atlantic Ocean doesn’t cool things down as much. Tall buildings and skyscrapers have the double effect of keeping heat in and winds at bay.

Averages

The average high in New York City during September’s 24ºC, which drops to a pleasant 16ºC at night. The sea temperature’s 21ºC, while humidity’s low. You’ll get 92mm of rain over eight days, and 12 hours of daylight with seven hours of sunshine each day. UV levels will be high so make sure you look after your skin in the sun and wear plenty of sun cream. The sun sets at 7.30pm at the start of September, and closer to 6.30pm at the end of the month.
