MORNING MOISTURE is a term used to describe the presence of DEW, DEWDROP, dewdrops, and dewiness in the early morning hours. DEW is a thin layer of water droplets that form on surfaces when the air temperature is lower than the surface temperature. DEWDROP is a single drop of DEW, while dewdrops are multiple drops of DEW. Dewiness is the state of being covered with DEW. All of these terms are associated with the presence of moisture in the early morning hours.
