The weather in NYC is collected by the US National Oceanic and Atmospheric Administration NOAA. See the temperature, wind, rainfall, sunrise/sun set, moon phases and ultraviolet.
For travelers to New York City the weather is certainly a factor in enjoying the visit. NYC has 4 seasons. Winter cold, spring and fall mild and summer hot. Describing this is very difficult. Our advice is check the forecasts. The people that live in NYC do not stop work or play for weather. Unless it's a hurricane or blizzard this city is in full operation 24x7. That's why there is the expression, "the city that never sleeps".
The temperatures are easy to locate using our weather widget at the top of the page. However, since most people carry a smart phone weather information is always accessible.
We suggest visitors plan for outdoor and indoor activities. Also plant to divide the city into boroughs. Each borough offers interesting points of interest. For Manhattan divide Manhattan Island into downtown - Wall Street, the Battery, Midtown and Uptown.
