For much of the month, the UK was under the influence of a westerly weather type, with a sequence of Atlantic depressions tracking across the country. A sequence of particularly deep lows between the 9th and 15th brought some very stormy conditions to Scotland, especially the Western and Northern Isles, as well as plenty of rainfall. The first half of January was very mild, but the second half was colder, with mostly quieter weather but some snowfalls at times, especially across high ground in the north. There were some sharp frosts with temperatures lower than at any time earlier in the winter or during the whole of last winter.
The provisional UK mean temperature for January 2015 was 3.7 °C, which is 0.1 °C above the 1981-2010 long-term average. Relative to average, south-west England was warmest and Northern Ireland coldest. Rainfall was above average in many areas, but especially much of Scotland; the overall UK rainfall total was 126% of average. Sunshine was well above normal in most places, especially eastern areas, and the UK received 126% of average sunshine hours. It was provisionally the UK's equal-fourth sunniest January in a series from 1929.
A maximum temperature of 16.5 °C was recorded at Exeter Airport (Devon) on the 9th. A minimum temperature of -13.7 °C was recorded at Loch Glascarnoch (Highland) during the daytime on the 19th. In the 24 hours ending at 0900 GMT on the 12th, 77.4 mm of rain fell at Achnagart (Highland). A wind gust of 113 mph was recorded at Stornoway Airport (Western Isles) on the 9th. Snow depths of 30 cm were recorded at Tulloch Bridge (Highland) and Aviemore (Inverness-shire) on 14th, and also at Buxton (Derbyshire) on the 30th.
