Even in sunny Florida it is cold! Yesterday morning before I left for school it was 22F!
22F is cold?
You have got to be kidding me.
You guys have no idea what a real man's winter is.
22F is very confortable. In fact, it is the ideal winter temperature, higher than that, your socks get wet either from the sweat or the melting snow.
A real cold day is at most 5 F (-15 C) and even then you need harsh winds to even feel that it is cold.
At this temperature, unprotected fingers and toes will hurt in a matter of minutes, same goes for ears.
But even then, a half decent pair of gloves and a hat will allow you to enjoy the walk and the chill feeling on your cheeks and nose.
Then you get to -4 F ( -20 C) This temperature is felt the same way as 5 F, only this time, the cold can pass through your jacket and come to annoy you even if just a little. A good temperature for ski and other intense activities as the heat generated from your activities will dissipate easily. However, unless you are skying or playing hockey, you will feel even the slightest of winds.
But then, you can get to - 13 F ( -25 C). At this temperature, you absolutely need to protect your neck. And seal your jacket to your body. This is when you see the difference between good quality clothes and those of less than good quality. A good pair of gloves and boots will protect you if you stay on the move, waiting for the bus is a nightmare. You probably want to wear wool under your coat and a hat that cover your face : Your nose will run and the running will freeze, keep your mouth shut and your lips will dry. Don't try to humidify them or they'll freeze. Your eyes will tear and your tears will freeze on your eyelash. Now this
is cold weather. And don't forget the wind, the wind will make it even worse.
Sometimes, you can even get lower than -22 F (-30 C). Below this temperature, especially with winds, it is not unheard of for public school to close. Take every bad thing that can happen to your body at -13 F and apply it even with good clothing. At this temperature, your unprotected flesh will burn from the cold in two or three minutes. If you fall asleep at this temperature, there is a good chance that you will die. You can also suffer permanent injuries if you stay exposed for extended periods of time. There are about a dozen days or so that get to temperature this low each year in Montreal. Sometimes more. If you talk about a temperature so cold that it is painful, I will imagine you mean this temperature.
