In June 2024, early summer heat waves hit both the western and eastern United States. Temperatures in July have not brought much relief.

In June 2024, early summer heat waves hit both the western and eastern United States. Temperatures in July have not brought much relief.

The map above shows air temperatures across the U.S. on July 10, 2024. The map was produced by combining observations from satellites and other sources with temperatures predicted by a version of the GEOS (Goddard Earth Observing System) model, which uses mathematical equations to represent physical processes in the atmosphere. The darkest reds indicate temperatures of more than 104 degrees Fahrenheit (40 degrees Celsius) at about 6.5 feet (2 meters) above the ground.

In the West, areas of intense heat are visible across many areas west of the Rockies, from Mexico to Canada. According to the National Weather Service (NWS), temperatures commonly surged over 100°F on July 10, causing widespread heat risk. On that same day, parts of the East—from South Carolina to Massachusetts—were under heat warnings or advisories. High humidity boosted the heat index to over 100°F in some places. The higher the heat index, which indicates how hot it feels when accounting for both temperature and relative humidity, the harder it is for the human body to cool itself.
