Early May can be somewhat cool so a light jacket, windbreaker or just a sweater may be needed. There are also often brief showers throughout the day, so be sure to carry an umbrella and have waterproof shoes.  However, by month’s end, you can usually expect to dress for summer. It can get very hot in the city, so shorts and a light top are often all that is needed. Also, don’t forget a water bottle and good walking shoes to make the most of your time in NYC!
