The averaging period used for the following assessment was 1981-2010.
UK climate video
At the start of January, the UK was in a very unsettled regime dominated by low pressure, with frequent active depressions and fronts, and record-breaking rainfall totals in north-east Scotland. It was a generally mild month in the south, but it turned colder everywhere for a few days around mid-month, with widespread frosts, and some snow, mainly over high ground and in the north. The last third of January was generally very mild and wet with strong winds, although Scotland was colder at times with wintry showers. Storm Gertrude caused widespread disruption near the end of the month, with damaging winds.
The UK mean temperature was 4.6 °C, which is 0.9 °C above the 1981-2010 long-term average. England and Wales were mildest relative to average, while northern Scotland was very close to average. With 148% of average rainfall, it was the equal-fourth wettest January in the UK series from 1910. Most of eastern Scotland and parts of north-east England had two to four times the normal rainfall, and for eastern Scotland it was the second wettest calendar month in the series, with December 2015 having been the wettest. The rain thus fell on already saturated ground and caused widespread flooding in Aberdeenshire. It was a wet month across most other areas but rainfall was much closer to average in western Scotland, the Midlands and East Anglia. Sunshine was generally near or above average in the south, but it was a dull month elsewhere, with 79% of average sunshine overall.
The UK monthly extremes were as follows: A maximum temperature of 16.5 °C was recorded at Achnagart (Highland) on the 24th. A minimum temperature of -12.4 °C was recorded at Kinbrace (Sutherland) on the 19th. In the 24 hours ending at 0900 GMT on the 27th, 116.2 mm of rain fell at Nant-Yr-Ysfa, Rhondda (Mid Glamorgan). Wind gusts of 91 knots (105 mph) were recorded at Lerwick and Baltasound (both Shetland) on the 29th. A snow depth of 16 cm was measured at Spadeadam (Cumbria) on the 14th.
This satellite image shows clear skies across Wales and western England on Wednesday 20 January, with the UK under the influence of high pressure to the east. Lying snow can be seen across the high ground of Wales, the Pennines and Lake District. Low level fog can be seen in the Vale of Gloucester, and this remained in place all day; in the fog the daily maximum temperature on 20th was only 2.3 °C at Pershore, Worcestershire. The preceding night saw a sharp frost with temperatures falling widely below -5 °C across England and Wales. Copyright Met Office / NOAA.
Although there was only one named storm this month (Storm Gertrude on the 29th) the legacy of the exceptionally wet December meant an ongoing threat of flooding in January in parts of the country, especially the north. North-east Scotland was especially affected by flooding from persistent heavy rain, and by the 13th, Aberdeenshire had already recorded its wettest January in a series from 1910.
Localised flooding occurred over many parts of the UK during the first three days. On the 4th, widespread flooding affected eastern Scotland, especially Aboyne (Aberdeenshire), causing road and rail closures, and there was heavy erosion on the banks of the river Dee. Flooding continued to cause transport problems across north-east Scotland and north-east England on the 5th.
Northern Ireland was also affected by flooding, and on the 6th/7th, homes and businesses on the shores of Lough Neagh were flooded as water levels reached a 30-year high. There was also transport disruption and a large landslide on farmland in County Antrim. In eastern Scotland, the 7th saw numerous road closures due to flooding, Blair Atholl (Perthshire) was cut off for a time and rail line between Aberdeen and Dundee was closed. The flooding in eastern Scotland continued into the 8th.
On the 11th, localised flooding of road and rail routes were reported across East Anglia and the Home Counties, with school children having to be rescued from a bus trapped in flood water in Farnham (Essex).
On the 13th and 14th, snow caused road closures in parts of Scotland and northern England, most notably closures of the A68. The 16th and 17th had further disruption due to snow, with significant disruption to Scottish football fixture lists and East Midlands Airport was closed for more than four hours.
On the 26th, two lorries were blown over on an exposed bridge on the A1, and the M8 was also closed fro a time. The M9 near Falkirk was closed due to surface water flooding, and pupils at Aberfoyle Primary School had to be rescued by boat after the nearby River Forth burst its banks. Further south, flooding affected road and rail links in Cumbria, with more localised property flooding. Coastal flooding closed a rail line in North Wales, and over 1,000 properties in Wales were affected by power outages.
On the 27th, flooding was reported in Northern Ireland, affecting a housing estate in County Down, while there was a landslide on the A2 and some road flooding. There were widespread reports of transport disruption across southern Scotland, with the Borders towns of Hawick and Jedburgh affected. The A7 and A68 south of the towns were both closed, and the rivers in both towns burst their banks. Road and rail travel across northern England was disrupted by flooding, particularly across Cumbria.
Storm Gertrude on the 29th closed the Tay and Forth Road Bridges during the morning, caused localised landslides, fallen trees, isolated cases of structural damage, overturned lorries on the M9, A96 and M74, closed schools, left around 8,500 properties without power across Scotland, and a man was taken to hospital in Edinburgh with head injuries after being hit by windblown debris. Across northeast England, around 6,500 properties suffered power outages, the Metro and east coast trains were disrupted due to overhead line problems and a small aircraft blown was over at Durham Tees Valley Airport.
Storm force winds for the Shetland Islands meant that all schools were closed, there were some power outages and overturned vehicles, but fortunately impacts were small considering the strength of the winds.
Snow on the 30th led to difficult driving conditions and some minor road closures in Scotland.
