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 November, the dew point typically varies from 52°F (very comfortable) to 61°F (comfortable) and is rarely below 46°F (dry) or above 64°F (mildy humid).
The time of the month between November 1 and November 30 is the most comfortable, with dew points that are neither too dry nor too muggy.
