The Problem with Humidity
Pretty much every weather app has a percentage listed for “humidity.” The full name for this metric is “relative humidity.” It tells us how much the air is saturated with water. Most people assume that a high relative humidity percentage is what determines how humid it feels, but that’s not entirely true.
Humidity can have a huge effect on how hot it really feels outside. Thankfully, weather apps typically include humidity numbers, but you’re probably looking at the wrong ones. What you should be checking is the dew point.
