The month of July is characterized by warm temperatures, sometimes hot and humid with daytime average high temperature in the low to mid-80s F (26-29 C).

Average July Temperatures NYC

Expect overnight lows mostly in the mid to upper-60s F (17-21 C).

How Hot Does NYC Get in July?

About 6-7 days this month will see afternoon high temperatures at 90 F (32 C) or higher while a few of the cooler nights can dip down into the upper 50s F (14-15 C).  

In the past, July has seen extremes here as high as 106 F (41 C) and as low as 52 F (11 C).


High temperatures aren't the only thing making NYC feel hot in July. Humidity is arguably more important.

New York City can get very humid in the summer months, and in July, you can expect a daily average of around 70% humidity.

This means that the heat index is often much higher than the recorded temperatures and you are likely to feel sweaty outdoors.

New Yorkers refer to this as muggy weather.


About 21 days this month will see either sunny skies or at least partly sunny skies.

Some rain or showers can be expected on about 10 days this month, however, only about 3 of these record significant rainfalls of 1/2 inch (13 mm) or more.  

Most of the rain this month comes in the form of showers and thunderstorms which can be accompanied by strong gusty winds.

Due to the level of relative humidity, the weather forecast might show potential rain each day, but this doesn't actually happen in reality.
