Dew Point is a particular temperature at which the air becomes saturated with moisture. At this point it produces dew. It is the point at which condensation begins as a result of the saturation of water vapour in air. Dew can be seen in early hours of the morning and it forms a wet blanket of dew drops on almost all surfaces. Though dew point can occur in the day as well it is most common to observe dew forming in the early morning hours.

Similar to Dew Point is Frost Point but it applies to the saturation point of ice in air. They are similar concepts differing due to the fact that ice forms in the air only at extremely cold temperatures.

Dew point is very closely associated to relative humidity. The Dew Point is generally closer to the temperature of the air if humidity is high and vice versa.
