Dangerous 100-Degree Heat Wave Hits NYC: See Latest Forecast

NEW YORK CITY — New York City will get its first heat wave of the summer this week, bringing dangerous triple-digit temperatures, poor air quality and intense humidity, forecasters said.

The National Weather Service has issued an "Extreme Heat Warning" in New York City from now until 8 p.m. Tuesday, with heat index values of up to 107 degrees during the day expected.

The lows at night are in the 80s, and may not offer much relief with high humidity persisting.

"This extreme heat will not just be uncomfortable and oppressive, it will be brutal and it will be dangerous to those who spend extended periods outside,” Mayor Eric Adams said. "We are in constant communication with our utility partners and monitoring the electric system, and city government is leading by example by reducing energy usage."

New York City is also under an "Air Quality Alert" from 11 a.m. until 11 p.m. on Monday, due to pollutants in the air.

New Yorkers who are sensitive to air quality, like people with asthma, young children, and older adults, will want to avoid spending a lot of time outside or doing strenuous activities outdoors, officials said.

To reduce the amount of pollutants in the air, New York's Department of Environmental Conservation recommends using mass transit instead of driving, turning off all unused electrical appliances, and cutting back on any outdoor burning, like smoking or grilling.

Though the heat wave spans Monday and Tuesday, the extreme temperatures may continue into Wednesday, but temperatures should trend cooler Thursday into Friday, with a few scattered rainstorms, according to the National Weather Service forecast.

"After a cooler, rainier start to June, this sudden heatwave may catch some New Yorkers off guard," said New York City Emergency Management Commissioner Zach Iscol.

"As temperatures soar to nearly 100 degrees this week, we urge all New Yorkers to take the heat seriously. Stay hydrated, avoid strenuous outdoor activities, and, most importantly, find places in your neighborhood to cool down, so you and your family avoid the dangerous consequences of heat illness."

It is important to take precautions during this heat wave, especially for those who are working outside. According to Scientific American, extreme heat is the number one weather-related cause of death in the U.S. It kills more than hurricanes, floods and tornadoes combined most years.
