The first week was mild, but very stormy at times, with a major storm on 3rd affecting southern Scotland in particular. It remained wet in the north and west, but gradually turned more settled towards mid-month, with some dry sunny days and night-time frosts, especially in eastern areas. A mainly westerly airstream brought a return to unsettled conditions later in the month, with rain and hill snow, before it turned much colder but dry at the end.
Temperatures overall were 0.8 °C above the 1971-2000 average. Rainfall totals varied widely, from more than 150% of normal in parts of the north to only half the normal for Fife and the eastern Borders. It was sunnier than normal except for south-west Scotland and the Western Isles, provisionally the second sunniest January in the series (since 1929) for eastern Scotland.

The 1st and 2nd saw strong westerly winds, with frequent showers mainly in the north-west. The 3rd was a very stormy day, with gale-force winds and squally showers for most of the country. There was a gust of 102 mph recorded at Edinburgh Blackford Hill. The 4th started dry in the east, but rain spread from the west during the afternoon with some strong to gale-force winds again. 58 mm of rain was recorded at Cluanie Inn (Highland), and Dundrennan (Dumfries & Galloway) had a gust of 76 mph. The windy theme continued on 5th with gale-force north-westerlies, and a scattering of showers mainly in the north-west. A gust of 65 mph was recorded at Peterhead (Aberdeenshire). The 6th started bright, but patchy light rain spread from the west during the morning. It remained windy with scattered showers in northern areas on 7th, then it was dull and damp on 8th with rain and drizzle for most areas. The 9th was a brighter day with sunny spells and only scattered light showers. The north-west saw some heavy rain on 10th, with 28 mm falling at both Cassley and Resallach (Highland), whilst other areas were generally dry but cloudy.
11th to 20th
A generally dry, mild but cloudy start on 11th although rain and strengthening winds spread into north-western areas by late afternoon. A windy start on 12th with Loch Glascarnoch (Highland) recording a gust of 68 mph, but winds eased during the morning to give a cooler, brighter day. After a chilly start, 13th was dry with sunny spells. The settled theme continued on 14th and 15th; after frosty mornings (down to -6 °C in parts of the Highlands and Borders), these were dry days with sunny spells. The 16th was dry with sunny spells too, after a cold and in places foggy start, with -10.5 °C recorded at Aboyne (Aberdeenshire). Another cold start on 17th, temperatures falling close to -10 °C in parts of the Highlands; scattered showers were mainly confined to the north-west. A band of rain cleared overnight to leave showers on 18th, mainly for western and northern areas, becoming wintry on higher ground. On 19th a band of showers, with snow for higher ground, spread from the west, giving a snow depth of 8 cm at Aviemore (Highland). The 20th started bright, but a band of rain spread from the south-west during the day accompanied by strengthening winds.

There was more sunshine on 23rd, especially in eastern areas, whereas the showers continued in the north and west. The 24th started with a band of rain (snow for higher ground) spreading from the west, although this cleared during the morning to leave a dull and cloudy day. The 25th was milder and drier than of late, with some strong winds for western areas. However, a band of rain spread from the west during the evening which cleared overnight giving a colder day on 26th with a band of rain and snow spreading eastwards for central areas during the afternoon. A frosty start on 27th, with Loch Glascarnoch recording -6.9 °C, then a bright but chilly day with only a few scattered snow showers mainly for the north, whilst 28th remained chilly but was generally dry until rain edged in to the Western Isles during the afternoon.
