Why do outdoor misting systems work more efficiently in low humidity areas?
Areas with low humidity have less moisture in the air. Therefore it is easier for the mist coming from your misting system to evaporate into the surrounding air. Areas with high humidity have a lot of moisture already in the air and it is difficult to evaporate more moisture into the air from your misting system. The more mist that evaporates, the cooler the surrounding air will feel.
