We all know that the wind can make a cold day feel even colder, but how much colder?
In the summer, additional humidity makes you feel hotter because it slows the evaporation of sweat off your skin. In the winter, even a slight breeze can dramatically speed up the evaporation of moisture from your skin, making you feel colder.
This chart shows how quickly wind speeds can drop the apparent temperature to your body. For example, if the temperature is 20 degrees and the wind is blowing at 20 mph the wind chill is 10 degrees below zero!
Use this chart to help plan for the expected chill in the air until our summer heat returns.
