Do not live near bodies of water. Also in the US south where we’ve had excessive heat warnings. I suppose the sun plays into it, but help me understand please. Thank you

If you take one cubic meter of air from somewhere on earth, it’ll have a bunch of different gasses in it. Nitrogen mostly, then oxygen and some amount of water.
The water will be in vapor form, completely invisible, if you pick that cubic meter from a dry place, and it will be in vapor and liquid form if you pick it from inside a cloud or a foggy place. The liquid part will be in tiny droplets in suspension that will make is look more opaque / foggy.
If your cubic meter is foggy, you can make it clear again by heating it up. It’ll cause the droplets to evaporate into vapor and become invisible.
If your cubic meter is clear, you can make it foggy by cooling it down. Some of the vapor will condense into tiny droplets and fog up the space.
When temperature drops at the end of the day, some of the vapor in the air can turn to droplets and deposit as dew on the ground. If the air is quite dry, it might not reach that point, but it will get closer to that point, making evaporation of already liquid water slower. So clothes will dry slowly. Your sweat as well, which translates to us to “feeling humid”.
