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.

The lowest average wind speed of 9 mph (gentle breeze) occurs around November 3, at which time the average daily maximum wind speed is 13 mph (moderate breeze).
