September 2026 in New York shapes up around the 25th anniversary of 9/11, free rooftop tours with expanded capacity, and 2-for-1 Broadway tickets. These three items give a September trip a clear shape: one reflective morning, one free view, one festival afternoon.
Family events for the 9/11 anniversary
This September marks 25 years since the attacks. New York Family's roundup collects events for kids and parents across the city, built for families to mark the anniversary together. Check the list before you plan your day. Some events will be more appropriate for younger children than others, so read the details. If you are traveling with children, factor in extra time for the experience rather than rushing to the next attraction.
Free rooftop tours with expanded access
The city now allows larger groups on the free Centre 360 tours at the 36th floor of the Manhattan Municipal Building, according to 6sqft. The 36th-floor panoramic experience sits inside the Beaux-Arts building, and the expansion follows stronger demand. Put this high on your list if you want a free view over lower Manhattan. Demand has already pushed the city to add capacity, so treat the tour as a priority slot in your schedule.
September festivals and discounted Broadway
Secret NYC's September list includes the biggest Italian festival in the US, NYC's original county fair, and 2-for-1 Broadway tickets. The two-for-one deal only helps if you already know which show you want. The festival and fair are large outdoor events, so go early in the day if you want to move through them without fighting crowds. Gothamist's morning roundup notes that 'Dolly: A True Original Musical' is still set for Broadway.
