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 35°F (dry) to 48°F (dry) and is rarely below 29°F (dry) or above 55°F (very comfortable).
Over the course of November typical wind speeds vary from 5 mph to 20 mph (light breeze to fresh breeze), rarely exceeding 30 mph (strong breeze).

The lowest average wind speed of 12 mph (moderate breeze) occurs around November 1, at which time the average daily maximum wind speed is 19 mph (fresh breeze).
