Daytime temperatures
January 1997 was the coldest January in the UK for over 10 years, and the third successive month with daytime temperatures more than 1°C below average. Most of the cold weather, however, was experienced during the first 10 days of January after which temperatures were mostly above average. There was a large contrast in the anomalies between Scotland (warmer), and the southwest of the UK (2°C to 3°C colder than average). Exmouth, for example, was colder during January than many locations in Scotland.
Rainfall
The UK was exceptionally dry during January, averaging nationwide only 31% of usual January rainfall. There were no exceptions to this picture, although Scotland was rather less dry than elsewhere with totals about 50% of average. Lowestoft recorded less than 10mm of rainfall, barely 20% of average January rainfall. Although October and November 1996 were wet months, both December and January have been very dry and these two winter months are important for recharging groundwater supplies.
Sunshine
Averaged for the country as a whole, sunshine in January was close to normal. But there were large contrasts between the north and west of the country (generally sunnier than average) and the south, central and east (generally duller). Aberdeen enjoyed three times as much sunshine as Scarborough, and Anglesey more than twice that recorded by Birmingham. January brought an end to a sequence of seven successive months in the UK which have been sunnier than average.
