The best time to visit New York City depends on your personal preferences and the activities you want to do during your trip. New York City has a temperate climate, with temperatures ranging from around -5°C (23°F) in the winter to over 30°C (86°F) in the summer.

If you want to enjoy outdoor activities and take advantage of the city's many parks and green spaces, the best time to visit New York City is during the spring or fall. During these seasons, the weather is pleasant and sunny, with temperatures ranging from 10°C to 25°C (50°F to 77°F).

If you don't mind the cold and enjoy experiencing the city's winter holiday traditions, you might consider visiting New York City during the winter months. The city is known for its elaborate holiday window displays and festive atmosphere, and the colder weather means that you'll have fewer crowds to deal with.
