It's cold in winter and the hot water is cold, but it's still smoking. What kind of water phenomenon does this belong to?

Because when the weather is cold, the water in the air will soon reach saturation, so we will see smoke on the water. If the weather is very hot, the water vapor saturation in the air will become great, so it is not easy for the water vapor in the air to reach saturation, and we will not see smoke on the water surface in summer.
