May
May is one of New York City’s loveliest months. The temperature ranges from 10-26°C, so it’s usually warm but not very hot, and without the humidity that you will find during the summer months.

June
June days grow warmer and warmer as summer approaches, though it’s usually not too hot or humid to comfortably enjoy being outdoors. Shorts and sandal season is in full swing, and the month’s long days (the sun sets around 8:30pm) are perfect for catching an outdoor concert or ballgame at Yankee Stadium – barring the occasional rainstorm. (Average Max Temperature: 25°C. Average Precipitation: 92mm.)
July
The hottest month of the year, expect temperatures to range from 21-35°C, with an average high of 28.2°C. The humidity is on the rise as well, especially as August nears, though ample shade from trees and tall buildings means it’s usually not so uncomfortable that you can’t enjoy a walk in the park, or lunch or dinner in a sidewalk café. Expect quieter streets as locals have headed for the cooler coast. (Average Max Temperature: 28.2°C. Average Precipitation: 97mm.)
August
Even though July is NYC’s hottest month by temperature, August is the most humid. It is immensely sticky in the city this month, with the climbing daytime humidity often bringing late afternoon and early evening thunderstorms which blow over quickly. Temperatures can be a full 10° hotter in the subways, so it’s a good idea to consider a taxi as you make your way from one air-conditioned attraction to the next. (Average Max Temperature: 27.7°C. Average Precipitation: 87mm.)
September

October
October is New York’s driest month of the year. It consists of mild to chilly temperatures and crisp autumn air.

Average Precipitation: 73mm.)
