Windchill information

Windchill is the term used to describe the rate of heat loss on the human body resulting from the combined effect of low temperature and wind. As winds increase, heat is carried away from the body at a faster rate, driving down both the skin temperature and eventually the internal body temperature.

To use the chart below, select the actual temperature from the top row and the windspeed from the left hand column.  Where the row and column intersect gives the apparent temperature.  eg at zero degrees with a wind of 32kph the temperature you feel is more like minus 14!  – and that is cold.  This is typical of spring days on Snowdow: 10 degrees at the bottom, but at three and a half thousand feet it will be around zero, then add in the wind and very quickly it’s freezing.
