In this example, the reported dew point temperature is 58 degrees.
Dew points indicate the amount moisture in the air.
The higher the dew points, the higher the moisture content of the air at a given temperature. A state of saturation exists when the air is holding the maximum amount of water vapor possible at the existing temperature and pressure . When the dew point temperature and air temperature are equal, the air is said to be saturated. Therefore, if the air cools, moisture must be removed from the air and this is accomplished through condensation . This process results in the formation of tiny water droplets that can lead to the development of fog, frost, clouds, or even precipitation.
