This isn’t random bad luck. It’s a perfect storm of geography. Altnaharra lies in a natural frost hollow.
During clear, calm winter nights, cold air is heavy. It flows downhill like a freezing river and gets trapped in the valley.
The ground radiates heat into space. No clouds to trap it. Result? A deep, still, brutal chill that scientists call “radiational cooling.” Pretty fancy for “it got stupidly cold.”
What About England?
Scotland dominates the record books, obviously. But England has its own frosty victory.
The coldest temperature ever in England is -26.1°C. That happened in Newport, Shropshire, on the very same day! January 10, 1982 was a real barn-burner, but in reverse.
So even the English midlands can turn into a tundra. Pack a parka if you’re visiting the Welsh border in winter.
