The relative humidity typically ranges from 56% (mildly humid) to 86% (very humid) over the course of a typical November, rarely dropping below 43% (comfortable) and reaching as high as 99% (very humid).
The air is driest around November 30, at which time the relative humidity drops below 63% (mildly humid) three days out of four; it is most humid around November 1, rising above 80% (humid) three days out of four.
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 53Â°F (very comfortable) to 68Â°F (muggy) and is rarely below 44Â°F (dry) or above 76Â°F (very muggy).
Over the course of November typical wind speeds vary from 4 mph to 16 mph (light breeze to moderate breeze), rarely exceeding 22 mph (fresh breeze).
The highest average wind speed of 10 mph (gentle breeze) occurs around November 26, at which time the average daily maximum wind speed is 16 mph (moderate breeze).
The lowest average wind speed of 10 mph (gentle breeze) occurs around November 6, at which time the average daily maximum wind speed is 16 mph (moderate breeze).
