Why does humidity increase as temps drop late in the day?

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

So humidity (that you read on weather) Is typically relative humidity or how much water the air is holding relative to the maximum amount of water the air can hold at that temperature.  As air gets hotter it can hold more water, as air gets cooler it can hold less water.  So assuming no water condenses if it gets cooler the amount of water in the air stays the same, but the amount that the air can hold goes down causing relative humidity to rise.
