Extreme Heat

North Carolina is getting hotter

Extreme heat is when it stays very hot for a long time.

Most parts of NC are projected to see at least two or three extra weeks of very hot days, with temperatures 95°F or higher.

More hot days, hotter nights and longer heatwaves can cause serious health problems.

A thermometer held in front of the sun reads more than 100 degrees.

4 Ways to Stay Safe in Hot Weather

Stay Hydrated

Drink lots of water during the day — even if you’re not thirsty. Avoid too much caffeine or alcohol, which can make you more dehydrated.

Limit Time Outside

Try to avoid being outdoors during the hottest part of the day (usually between 11 a.m. and 4 p.m.). Wear lightweight, loose-fitting clothes, and take breaks in the shade or indoors.

Find Cool Places

If your home doesn’t have air conditioning and the temperature is above 95°F, go to a public building like a library or community center to cool off.
