Humidity is the amount of water vapour in the air around us. It is mentioned as a percentage usually. Humidity arises because of vaporization of water from various water bodies on Earth. Due to winds and pressure changes in air, the vapour travels from one place to another.
Due to heat during the day, there is more evaporation of water. At night there is not much of heat in the air. So there is less evaporation of water. Also humidity converts back to dew in the early morning. Generally if you watch some parks early in the morning, you find a lot of dew.
Thus humidity increases and then decreases depending on the temperature and pressure in the air. When air cannot hold more water vapour, then it becomes saturated. Then water vapour liquefies and drops out of air.
