NYC in September

September is one of the best times to visit New York City. By then, the weather has cooled off from summer, but it's still warm enough to enjoy being outside. At the beginning of the month, the beaches and pools are still open. And with kids back in school, there aren't as many tourists in the city, meaning you'll have shorter lines for attractions and an easier time getting reservations. Plus, there is a ton going on in September from Labor Day parades, fashion shows, and Italian feasts.

New York City Weather in September

September in New York City averages high temperatures of 76 degrees Fahrenheit (24 degrees Celsius) and the average low temperature is 61 degrees Fahrenheit (16 degrees Celsius). You'll want to wear cool clothes during the day but bring a jacket for when it gets chilly in the evening. It will get colder as the month goes on and while early September still feels like summer, late September is considered the official start of autumn.

September is also a relatively dry month with only seven days of rain on average. Still, you'll want an umbrella and a rain jacket if you happen to be in the city during those days. At this time of year, you'll start to notice that the days are getting shorter, but can still enjoy anywhere between 12 and 13 hours of sunlight.

What to Pack

Packing for September in New York is all about layering. For the day you should have summer clothes: shorts, t-shirts, and dresses, but mornings and nights can be cool, so don't forget to bring a light jacket and pants with you. You'll also want an umbrella, rain jacket, and waterproof shoes for rainy days. The streets are full of puddles when it rains, especially on the street corners, so you'll want to make sure your feet stay dry.

September Events in New York City

With summer vacation over, there is a range of annual events that span different industries and interests. Many are held outside, letting you enjoy the last weeks of summer. Some of these events may be canceled or held virtually in 2020, so be sure to check the organizer's website for more details.

  • Labor Day: Labor Day is a federal holiday that is always observed on the first Monday of September and while many New Yorkers leave the city for the three-day weekend, you can attend events in towns, such as the West Indian Day Parade, sometimes called the Labor Day Carnival.
  • New York Fashion Week: During the second week of September, New York City streets fill up with models, designers, bloggers, fashion editors, and other style enthusiasts. Many of the runway shows and pop-up exhibits are open to the public and you can find tickets on the event's official website.
  • NYC Broadway Week: Every September, Broadway shows become much more accessible with two-for-one tickets during NYC Broadway Week.
  • The Vendys: This is an annual street food competition that pits the best street food vendors in New York City against each other in a delicious competition on Governors Island.
  • Feast of San Gennaro: You can't walk through Little Italy in September without running into the Feast of San Gennaro. Here, you can gorge yourself on authentic Italian treats and learn more about Italian-American culture.
  • US Open Tennis Championship: You can buy tickets online to this grand slam tournament that attracts the world's top tennis players to the Billie Jean King National Tennis Center in Queens during the first week of September.

September Travel Tips

  • If you are traveling to New York City over fashion week, Labor Day, or the US Open, book your hotel early to avoid sell-outs. Hotels are more expensive during those times so consider staying in Queens or Brooklyn as a cheaper alternative.
  • On Labor Day museums and attractions are open, but government agencies including banks and libraries aren't.
  • September is a month in-between seasons, so if you're traveling in the first half of the month, pack for the summer. If you're traveling in the second half, pack for the fall.
