With an average temperature of , January 1963 remains the coldest month since January 1814 in
Central England, although for the UK as a whole and in
Northern England, Scotland and Northern Ireland February 1947 and February 1895 were colder, whilst December 2010 was also colder in Northern Ireland. Much of
England and Wales was covered in snow throughout the month. At various locations in the UK, it had been the coldest January on record for long established stations such as
Newquay and
Ross-on-Wye with the coldest January on record since 1891 and 1877 respectively. It was the coldest January at
Kew since 1838. In January 1963, the sea froze for from shore at
Herne Bay,
Kent. The sea froze inshore in many places, removing many British inland water birds' usual last resort of finding food in estuaries and shallow sea. The sea froze out to sea from
Dunkirk. However, it did not freeze in
Central London, partly due to the hot
effluent from two thermal
power stations,
Battersea and
Bankside. The removal of the multi-arched
London Bridge, which had obstructed the river's free flow, and the addition of the river
embankments, also kept the river from freezing in London as it had in earlier times (see
River Thames frost fairs). On 20 January, 283 workers had to be rescued by RAF helicopters from
Fylingdales, where they had been snowbound for several days.
Icicles hung from many roof gutterings, some as long as . On 25 January, there was a brief thaw that lasted three days. == February 1963 ==
