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 February, the dew point typically varies from 16Â°F (dry) to 29Â°F (dry) and is rarely below -2Â°F (dry) or above 38Â°F (dry).
Over the course of February typical wind speeds vary from 3 mph to 13 mph (light air to moderate breeze), rarely exceeding 21 mph (fresh breeze).
The highest average wind speed of 9 mph (gentle breeze) occurs around February 21, at which time the average daily maximum wind speed is 13 mph (moderate breeze).
The lowest average wind speed of 8 mph (gentle breeze) occurs around February 1, at which time the average daily maximum wind speed is 13 mph (moderate breeze).
