The Least Humid States

The average annual humidity in the United States ranges from 71.31%—82.01%. Humidity is a measure of the concentration of water vapor in the air, and it varies from state to state. What’s interesting is that all of the 6 states with the lowest average annual humidity are coastal states, with the exception of Michigan, which is surrounded on three sides by the Great Lakes. 

If it is very humid, the air will feel wetter, and you may even notice a change in how breathing feels if you’re breathing very humid air. When you’re in extremely humid, warm climates, the air around you that’s densely filled with water vapor will make it difficult for your sweat to evaporate like it would under normal circumstances. During instances like this, your sweat doesn’t evaporate because the air has reached a saturation point where it cannot take on any more water vapor. 

On the other hand, the opposite is true in dry climates. In the Death Valley desert of California, for instance, the air is so dry that even if it’s warmer than ninety degrees, you’ll hardly—if ever—notice you’re sweating because the air absorbs the moisture from your perspiration so quickly.
