The winter of 1962–1963 (also known as the Big Freeze of 1963) was one of the coldest winters on record in the United Kingdom. Temperatures plummeted and lakes and rivers began to freeze over.
In the Central England Temperature (CET) record, extending back to 1659, only the winter (defined as the months of December, January and February) of 1683–84 has been significantly colder, with 1739–40 being slightly colder than 1962–63. Over Scotland and Northern Ireland, where data do not extend back to 1740, the winters of 1813–14 and 1878–79 were certainly colder than 1962–63, as was the winter of 1779–80 in Scotland and 1894–95 in Northern Ireland.
This winter remains the coldest since at least 1895 in all meteorological districts of the United Kingdom except Scotland North, where the two winters of 1978–79 and 2009–10 were marginally colder.
The beginning of December was very foggy, with London suffering its last great smog before clean air legislation and the reduction in the use of coal fires had their full effect. A short wintry outbreak brought snow to the country on 12th–13th. A very cold easterly set in on 22 December as an anticyclone formed over Scandinavia, drawing cold continental winds from Russia. Over the Christmas period, the Scandinavian High collapsed, but a new one formed near Iceland, bringing northerly winds. Significant snowfall occurred as the air mass moved south and parts of Southern England in particular had heavy snow late on 26 December (Boxing Day) continuing into 27 December. The cold air became firmly established.
On 29 and 30 December 1962 a blizzard swept across South West England and Wales. Snow drifted to over 20 feet deep in places, driven on by gale force easterly winds, blocking roads and railways. The snow stranded villagers and brought down powerlines. The near-freezing temperatures meant that the snow cover lasted for over two months in some areas. Snow lay to 6 inches depth in Manchester city centre,9 inches in Wythenshawe, and about 18 inches at Keele University in Staffordshire. By the end of the month, there were snow drifts 8 feet deep in Kent and 15 feet deep in the west.
