New York is the most populous city in the United States and the center of the New York metropolitan area, which is one of the most populous metropolitan areas in the world. New York City exerts a significant impact upon global commerce, finance, media, culture, art, fashion, research, technology, education, and entertainment.
Weather: Spring in New York City is the best time to be in the city without doubt. Spring usually means less humidity and temps between 50-80 degrees. June occasionally sees a 90 degree day. An occasional humidity soaked heat wave can strike, but it usually feels nice the first time around. Spring is all about eating al fresco and enjoying the low humidity.
What to Wear: Bring an umbrella (always bring one - it's a walking city and you don't want to get caught in the rain), and bring layers. In May, a light spring jacket or a mid-weight sweater is probably the heaviest thing you'll need. You won't need these in June. Bring some shorts/skirts and hope for great weather. Otherwise, you can always buy anything warmer that you'll need. If caught in heavier rain, remember that many pharmacies in Manhattan sell plastic rain ponchos for twelve dollars or less: you may not like the color but at least you'll be dry.
Cost: Flights & hotel prices head north in the spring, but the heaps of tourists don't descend upon the city until summer. That doesn't mean things are a bargain, not by far. You have average odds at getting same day half price Broadway show tickets at TKTS booths.
Seasonal things to do: Roaming Central Park is absolutely essential. Walking over the Brooklyn Bridge (and hopping a subway back) is fantastic on a sunny day. The Tribeca Film Festival extends into May. Fleet Week occurs the week before Memorial Day weekend. Definitely catch a Mets or Yankees day game. Head to the Belmont Stakes in June and hope a Triple Crown winner is still possible. Watch/experience the National Puerto Rican Day Parade down 5th Ave in June. Mid-June features the Museum Mile Festival on the east side of the Park. Late June features the Jazz Festival at multiple sites (Carnegie, Bryant Park, etc.), as well as Lesbian & Gay Pride Week, which culminates in the largest parade of its kind in the world.
