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 October, the dew point typically varies from 46°F (dry) to 55°F (very comfortable) and is rarely below 40°F (dry) or above 60°F (comfortable).
The time of the month between October 1 and October 31 is the most comfortable, with dew points that are neither too dry nor too muggy.
