The effects of windchill when in the mountains
Windchill is a factor we take into account most times when we visit the high Sierras. We ignore it at our peril. A 32km hour wind at 0 degrees centigrade gives an effective -12.5 degree “feel” to the temperature. The chart below will help in ascertaining the dangers. Most likely from December to February each year, we can get -10 degree temperatures at 3000m on Mulhacen with winds of 56km per hour.
