Are you Hot or
Cold? More than likely, what you feel is not the actual temperature.
Wind and
Humidity, or a lack of either, can make the temperature feel hotter or colder
than it actually is!
Take a Look and
See Just How Cold It Really “Feels” Outside Today!!
|
|
This Table Will Give You A General Idea of The Present Wind
Chill Factor On A Cold And Windy Day.
The top bar (purple) is the actual temperature. The green
bar (on the left side) is wind speed.
Everything in between is what it “feels” like at the given
wind speed and temperature.
