Frost Point

The frost point is a temperature that is below 32° F (0° C), at which moisture in the air will condense as a layer of frost on exposed surfaces that are also at a temperature below the frost point.

The frost point is comparable to the dew point, the temperature at which water condenses in liquid form; both the frost point and the dew point rely on environmental data, including the relative humidity and ambient air temperature.
