The US is facing a massive week-long heat wave, with over 265 million people experiencing sweltering temperatures. Learn about the heat alerts, expected record-breaking temperatures, and safety precautions as the Northeast and Midwest brace for potentially dangerous conditions.

As summer officially begins this Thursday, the United States is bracing for what could be a record heat wave, with weather experts warning that temperatures in large parts of the country are expected to reach dangerous levels. Many areas are more keenly preparing for sweltering conditions, especially the Northeast and Midwest, where a “heat dome” is settling over the region.

Heat Alerts for Millions

by Monday morning, the National Weather Service had issued heat alerts for over 75 million people. That number is likely to climb even higher because forecasts have pointed to 150 million people experiencing temperatures over 32°C and 9 million possibly reaching over 37.7°C.

Over the coming days, approximately 265 million Americans—nearly 82 percent of the US population—can expect to be hit with temperatures higher than 32 degrees Celsius before the arrival of summer’s first official day.

The city will open 500 cooling centers as temperatures are expected to reach triple figures, and the NWS is expected to declare a heat advisory.

“We think we will reach the peak of the heat on Thursday and Friday, and some parts of our heat index are going to feel like 99 degrees,” Mayor Eric Adams warned. “We want to be clear: June is extremely early for this type of heat, and New Yorkers should not underestimate the heat.”

Record-Breaking Temperatures Across Multiple States

The heat alerts issued on Monday cover 17 states. Connecticut, Massachusetts, and New Hampshire were issued Excessive Heat Watches. Temperatures in Concord, New Hampshire, could top 38 degrees Celsius Wednesday—possibly breaking new daily record highs.
