Relative humidity is a measure that indicates the amount of water vapor present in the air relative to the maximum amount it could hold at a specific temperature. It is expressed as a percentage and indicates how saturated the air is with moisture.
For example, a relative humidity of 50% means that the air contains half of the maximum amount of water it could hold at that temperature.
A high relative humidity indicates that the air is close to being saturated with moisture, while a low relative humidity indicates that the air is drier.
