Before you step out into the cold, you might want to check out how cold you
will feel. As most people know, when the wind is blowing, a cold temperature can
actually seem colder than the thermometer indicates. Below is a chart that will
allow you to get prepared for the Arctic blast awaiting you outside.
To determine the wind chill, look at the temperature in the left column. Then
move across the chart to the right until directly under the speed of the wind
shown across the top of the chart. There you will see the perceived temperature
waiting for you outside in the winter cold.
For example, if the outside temperature is 10° F and the wind is blowing
at 15 miles per hour, the wind chill will require you to bundle up for a perceived
temperature of -7° F.
