The dew point (sometimes spelled dewpoint) is the temperature to which a given parcel of air must be cooled, at constant barometric pressure, for water vapor to condense into water.

The dew point is the temperature at which dew would form assuming all other conditions remained the same. The dew point is a function of the air temperature and humidy. The dew point temperature can never be higher than the air temperature. If the dew point temp and air temp are the same, than the humidity must be 100%. Okay, that's fine, but what ...

Dew point is the temperature at which water vapor saturates from an air mass into liquid or solid usually forming rain, snow, frost or dew. Dew point normally occurs when a mass of air has a relative humidity of 100%. If the dew point is below freezing, it is referred to as the frost point.

Dew-point is the temperature at which condensation of the vapour in the air takes place. When the temperature of the air has been reduced by radiation to the dew-point, dew is deposited and an amount of heat set free which raises the temperature of the air. Thus the dew-point will indicate what the minimum temperature of the night is likely to be, ...

Temperature at which the air becomes saturated with water vapour. At temperatures below the dew point, the water vapour condenses out of the air as droplets. If the droplets are large they become deposited on plants and the ground as dew; if small they remain in suspension in the air and form mist or fog
