On a warm sunny day with high humidity, the dew points could climb a little higher because of ‘corn sweat’. Corn fields don’t really sweat, but they do transpire moisture known as evapotranspiration, the natural process of water evaporating from plants to the air. An acre of corn can give off 3,000 to 4,000 gallons of water each day, according to the U.S. Geological Survey Office so it may extra humid out today.
