The averaging period used for the following assessment was 1961-1990.
Maximum temperatures were generally below average and around 1 °C below average across parts of southern England. It was the coldest December since 1996 for England and Wales for maximum temperatures. Minimum temperatures were well below normal across almost all of the UK, by as much as 2 °C in some western areas. It was the coldest December since 1996 for Wales and N Ireland, 1999 for Scotland and 2001 for England. Rainfall was below or well-below normal in most areas, only around 50% of normal over parts of England and Wales, but locally 150% in eastern Scotland. Sunshine was above normal virtually everywhere, approaching double the normal amount in some parts of England.
Westleton (Suffolk) recorded a maximum temperature of 14.7 °C on 20th. Aviemore (Highland) recorded a minimum temperature of -12.9 °C on 30th. Middlefell Farm, Mickleden (Cumbria) recorded 99.0 mm of rainfall on 19th. Copley (County Durham) recorded 21 cm of lying snow at 0900 UTC on 4th. Wind gusts of 82 mph were recorded at Capel Curig (Gwynnedd) on 4th, and at Blackford Hill, Edinburgh on 19th.
Generally cold first half then a milder, mainly dry, period towards Christmas before turning very cold by the new year. Rainfall mostly below normal. Sunshine generally above or well above normal. Temperatures around one degree below normal; coldest December since 2001.
1st to 3rd: A cold northerly flow for the first few days, with widespread frosts and icy conditions away from north-facing coasts. Sunshine and showers, wintry on hills, on 1st and 3rd. A more general area of rain, with sleet on hills, moved south during 2nd. Very cold nights with -11.3 °C at Shap (Cumbria), -8.2 °C at Keswick (Cumbria) and -8.0 °C at Leeming (N Yorkshire) early on 1st. Temperatures struggled to rise by day in the Midlands northwards, but nearer normal in the south.
4th to 5th: An Atlantic low gave rain, sleet and snow, the snow mainly confined to northern England, especially over Cumbria, the Pennines and north-east England. Accumulations of 5 to 10 cm were recorded in the Vale of York, and 15 to 20 cm over higher ground. Further south, a milder westerly flow meant rain or sleet was reported. There was a marked contrast in daytime temperatures, with barely 2 °C in the north-east on 4th but up to 11 °C on the south coast.
6th to 11th: A ridge of high pressure moved east during 6th and 7th leading to a spell of mainly dry, fine weather. However, there were sharp night frosts and freezing fog patches, with temperature minima of -8.5 °C at Topcliffe (N Yorkshire), -6.7 °C at Leeming and -5.6 °C at Hurn (Dorset). During 8th, a band of rain moved erratically south across northern parts of England, into the Midlands during the evening. A cold, showery northerly then set in bringing a return of sunny spells, wintry showers and night frosts.
12th to 15th: A change to less cold but more unsettled conditions as Atlantic lows moved in, becoming slow-moving to the north of Scotland and also over the continent. An occluding front moved east early on 13th, giving a period of very heavy rain for a time in many areas, with 53.0 mm at Shap (Cumbria) and 37.6 mm at Dunkeswell (Devon). Flooding was reported in parts of Devon, Somerset, Wiltshire and the West Midlands. Windy ahead of rain band, with gusts 40 to 50 m.p.h. quite widely. Turning drier and colder again on 14th and 15th albeit with a few showers.
16th to 18th: A changeable period. Staying cold in the south-east on 16th with freezing fog slow to clear. However, a change to milder conditions as south-westerly winds moved in by 17th. Thereafter, often very windy with periods of heavy rain and gales across northern areas, especially on 19th and again on 20th with reports of flooding over parts of the north-west. A good deal of dry weather in the south and temperatures rather mild or mild.
19th to 25th: Several days of mostly dry and mild weather. Westerly winds often brought cloudy skies, though a few bright intervals occurred mainly in the east. There was occasional drizzle across western coasts and hills. Temperatures were well above average on these days, with Westleton (Suffolk) recording a maximum temperature of 14.7 °C on the 20th.
26th to 31st: A return to very cold, but mostly
dry conditions. Easterly winds developed, ushering in some very cold low-level
air from the continent. Initially, cloud amounts were variable and most places
saw some decent sunny spells, but there were sharp frosts night and morning.
With time, cloud amounts tended to increase, and as winds fell light, freezing
fog became more of a problem and night frosts became locally severe. With
fog and low cloud persisting all day towards the end of the year, many places
on the 30th and 31st had daytime maxima below freezing including -2.6 °C at
Shap, and -3.6 °C at Keswick.
Night minima included -9.6 °C at
Shap and -7.2 °C at Woodford
Generally cold first half then milder period before Christmas before turning cold again. Rainfall below normal. Sunshine well above normal. Temperatures below normal; coldest December since 1996.
1st to 3rd: A cold northerly flow covered Wales for the first few days of the month, with widespread frosts and icy conditions. Sunshine and wintry showers on 1st and again on 3rd but a more general area of rain, sleet and hill snow moved south early on the 2nd. Very cold nights but temperatures nearer normal in the south by day.
4th to 5th: An Atlantic low brought rain, sleet and hill snow, clearing to blustery showers, these heavy and thundery at times during 5th. Windy in the west. After a cold start to 4th, temperatures recovered to near normal by day but with local frost and fog patches under lighter winds in the east.
6th to 11th: A ridge of high pressure moved east during 6th and 7th leading to a spell of mainly dry, clear or sunny weather with near-normal maximum temperatures. However, there were sharp night frosts and freezing fog patches. During 8th a band of rain moved erratically south into northern parts of Wales during the evening. A cold, showery northerly then set in bringing a return of sunny spells, wintry showers and night frosts.
12th to 15th: A change to less cold and more unsettled conditions as Atlantic lows moved in, becoming slow-moving to the north of Scotland and also over the continent. An occluding front moved east early on 13th, giving a period of very heavy rain for a time in many parts, 35.3 mm at St Clears (Carmarthenshire) late on 12th. Windy ahead of rain band, with gusts 40 to 50 m.p.h. quite widely. Turning drier and colder again on 14th and 15th, albeit with a few showers for a time and some lingering fog patches.
16th to 18th: A change to milder conditions as south-westerly winds moved in during 16th.

26th to 31st: The 26th saw a change too much
colder, and generally dry, clearer conditions, as the cloud cleared away
westwards. Largely sunny on 26th and 27th with sunny periods from 28th
to 30th, though the south-west of Wales cloudy on 29th. Becoming rather
