Dew point is often a better measure of how comfortable a person will find the weather than relative humidity because it more directly relates to whether perspiration will evaporate from the skin, thereby cooling the body. Lower dew points feel drier and higher dew points feel more humid.
Over the course of a year, the dew point typically varies from 14Â°F (dry) to 54Â°F (very comfortable) and is rarely below -0Â°F (dry) or above 59Â°F (comfortable).
