The coldest I remember was at some point in winter when I was ca. 18 years old.
A few highschool friends of mine and I made the "mistake" to go tobogganing up a mountain and drive down the 10 miles into the valley at 9pm or 9:30pm at night, after spending a few hours on top of the mountain in a restaurant to chat and drink a few shots (
I do this about 10 times each winter, also just a few days ago).
So, when we went up the mountain at ca. 5pm, it had ca. -12°C (10°F) down in the valley and some -18°C (0°F) on top of the mountain. The sky was blue and without clouds.
When we bumped out of the mountain restaurant at ca. 9pm though, it had something like -25° (-13°F) or -30°C (-22°F) up there.
And then we had to start tobogganing down 10 miles on our sleds, with ca. 30-50km/h (20-30 mph), because the gondola down was of course already closed at that time !
Imagine the wind chill while driving in this friggin' cold ! Probably -40 or -50°C (-40°F or -58°F) or something.
Of course, we all had good winter clothing and everything, including scarves, but when we arrived down there we still had icicles hanging down from the scarves and borderline frostbites in our faces (that were only covered with the thin scarves), as well as on our hands and feet.
I still have the pictures of us with icicles on us somewhere on one of my portable harddisks ...
Never again in these kinds of temps !!!
