Air humidity refers to moisture in the air. Too much humidity makes it feel muggy and ‘sticky’ out.
Too little humidity may mean dry skin and a ‘crisp’ feeling outdoors.
Air pressure can affect humidity. But how does air pressure affect humidity?
Here’s a look at the issue of air pressure and humidity in a nutshell:
- High pressure is a mass of descending (sinking air) and, usually, lower humidity. Sinking air and relatively lower humidity are major reasons why high pressure is often associated with fair weather.
- Low pressure is a mass of rising air. Relative humidity is usually higher in areas of low pressure; low pressure enables the air mass to hold more water at high altitudes and thus enhances the chances for storms.

I'm a weather geek from Florida who's been studying meteorology and watching weather patterns for years! I enjoy sharing little-known facts and fun stuff about the weather. I especially like sharing interesting details about weather events and conditions that can affect you… and how to prepare for Mother Nature's ever-changing weather patterns.
