I would say, most classify as moderate climates. But, I too, would need a more accurate definition of what the OP considers “hot.”
I’m in Charleston, SC. Our summer temperatures, can reach over 100°F, with humidity, usually over 85%. Our winters, are usually mild. Today, it will be 70° F. Alaska, would add a curve, to the country’s average temperature. As would Florida, and parts of the southwest.
