"People that live in Yellowknife, Dawson City or Iqaluit are used to experiencing very cold weather temperatures and they're more acclimatized to being able to deal with those kinds of temperatures," Proctor said. What is wind chill, anyway? "Wind chill indicates that the temperature your body is going to be experiencing or feeling is actually colder than the actual temperature," Proctor said. Wind chill can pose a risk to health, like hypothermia or frost bite. It's not an exact measurement, so that's why wind chill is often expressed as the "feel" of a temperature if there was no wind.
