Back in the day, I went on business to Israel for a week one January. It was anomalously warm, short sleeve shirt warm.
I then travelled to Finland with a change of planes at Frankfurt, where it was snowing. Landed at Helsinki and it was -40C (the only temperature that it the same in C and F). I saw locals at the airport taking fearsome looking thermal clothing out of lockers and though Oho I'm in trouble here. It is nose freezing up inside when you breath cold. My clothing was inadequate for the ridiculously cold temperature.
Eventually got to the hotel in a taxi with thick ice inside the windows, and our local marketer took me to the sauna there.
So in a single day, I'd gone from +22C to -40C then to +100C.
