What's the story?

The Big Freeze: Winter '63.

Ah, that takes me back.

Erm, showing your age a bit there. I jest, of course. It was a hugely significant and memorable period. According to the Met Office, 1963 was the coldest winter for more than 200 years.

Why are we reminiscing?

A new Channel 5 documentary will re-examine what is described as "arguably the most devastating weather event to hit modern Britain".

It began on December 24, 1962, when a belt of rain over northern Scotland turned to snow as it moved south, giving Glasgow its first white Christmas since 1938. The snow-belt reached southern England on Boxing Day, settling up to 30cm (12in) deep in places.

Blizzard conditions in the days that followed saw roads and railways blocked, telephone lines brought down, and some villages cut off. Snow cover remained in many places well into March 1963.

And it was cold?

Bone-chilling. Temperatures dipped to such extremes that rivers and even stretches of the sea froze. In Braemar, the temperature fell to -22.2C on January 18, 1963.
