Spring (April-May): Mild weather (50-70°F), cherry blossoms in Central Park and Brooklyn Botanic Garden, outdoor dining season begins, and fewer crowds than summer. Perfect for walking tours and park visits.
Summer (June-August): Warm to hot (70-85°F), peak tourist season with maximum crowds and highest prices. Excellent free outdoor concerts, movies in parks, and rooftop bars. Shakespeare in the Park and SummerStage events. Prepare for occasional heat waves and humidity.
Fall (September-November): Ideal weather (55-70°F), stunning foliage in parks, especially late October. Fashion Week, New York Film Festival, and Halloween Parade. Less crowded than summer, pleasant temperatures for exploring.
Winter (December-February): Cold (25-40°F) but magical with holiday decorations, Rockefeller Center Christmas tree, ice skating rinks, and New Year's Eve in Times Square. Indoor attractions are less crowded (except holidays). Bundle up! January-February offer lowest prices and smallest crowds.
Best Overall: Late April-May and September-October offer optimal weather and manageable crowds.
