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 typical May, the dew point typically varies from 63°F (mildy humid) to 75°F (very muggy) and is rarely below 55°F (very comfortable) or above 78°F (oppressive).
