Top 10 Hottest U.S. Cities In The Summer

(Mix 93-1) The summer of 2025 honestly hasn't been all that brutal in East Texas, yet. But we know how August and September can be around here.

Yes, our temperatures have been flirting with the 100° mark, and it's felt well over 100° with the humidity factored in, but we have yet to hit the triple digits, something we normally do by this time.

How East Texas Compares to Other Cities

Now other parts of the country have been steaming and/or baking and suffering just like we have. Take, for instance, Phoenix, Arizona. It's 110° there all week long, and it feels like 106° in Miami, Florida.

Miami feels much like East Texas, with its humidity, and Phoenix, well, as they say, it's a dry heat. But let's be honest, 110 with no moisture is just like our 110° with humidity - heat is heat, and it's hot!

No matter where we live, we've accepted the summer conditions and the fact that our electric bills are going to soar this time of year too!

What Is a Heat Dome?

A recent term that many are hearing more of is ... heat dome.

I've only heard this phrase mentioned once so far this summer. A heat dome happens when high pressure sits over a region and acts like a lid on the atmosphere.

While warm air tries to escape, the high-pressure dome forces it back down to the earth. With little or no variation in temperature, the hot air becomes trapped and is not replaced by cooler air, which usually happens.

Oftentimes, a heat wave results thanks to this phenomenon. The good news is that they don't last forever; heat domes will move and retrograde, and eventually, they will dissipate.
