We base the humidity comfort level on the dew point, as it determines whether perspiration will evaporate from the skin, thereby cooling the body. Lower dew points feel drier and higher dew points feel more humid. Unlike temperature, which typically varies significantly between night and day, dew point tends to change more slowly, so while the temperature may drop at night, a muggy day is typically followed by a muggy night.

The chance that a given day will be muggy at Melrose Gunnery Range is essentially constant during April, remaining around 0% throughout.

For reference, on August 7, the muggiest day of the year, there are muggy conditions 3% of the time, while on October 29, the least muggy day of the year, there are muggy conditions 0% of the time.
