UK last month

January 2024

January started on a mild, wet and unsettled note, continuing the theme of much of the autumn and December – i.e. a relentless succession of Atlantic low pressure systems. The eighth named storm of the 2023-24 winter, Henk, on the 2nd brought heavy rain and strong winds – including a gust of 70Kt (81mph) at Exeter Airport. With rivers full and the ground already saturated from the persistent rain throughout December, the extra rainfall from Henk resulted in significant flooding problems, particularly from the River Trent. By the 5th, most of central and south-east England had already received two-thirds or more of the whole-month average rainfall. However, fortunately after this the weather regime changed dramatically with high pressure becoming established across the UK and bringing dry, sunny conditions and a marked drop in temperature. Just before mid-month, a northerly flow of Arctic Maritime air brought snow showers mainly across northern areas (although not especially unusual for the time of year). Northern Scotland, in particular Shetland, experienced several days of snow between the 16th and 20th. The cold but dry conditions persisted through the middle of the month until they were brought to an abrupt end with the arrival of the ninth and tenth named storms on the 21st to 24th. Storms Isha and Jocelyn brought strong winds and rain to much of the UK, but also milder temperatures which continued to the end of the month. Storm Isha was especially impactful, prompting extensive amber warnings for wind across the UK and resulted in a gust of 86Kt (99mph) in Northumberland.

Temperatures for January started off cold, with maximum temperatures around 1.0 to 1.5°C below average in many areas. However, the colder conditions early in the month were compensated for by much milder conditions towards the end of the month, resulting in close to average temperatures for the UK for the month as a whole (anomaly -0.1°C). The UK experienced a new daily maximum temperature record for January on the 28th, with 19.9°C recorded at Achfary, Sutherland. Rainfall was close to average levels across the UK (97% of the long-term average), with the wet start and end of the month compensated for by the dry spell mid-month. Wales and northern England bore the brunt of the rainfall, while Northern Ireland was much drier (75% of the long-term average). Much of the UK experienced above-average sunshine hours (128% of the long-term average).

The UK monthly extremes were as follows: A maximum temperature of 19.9°C was recorded at Achfary (Sutherland) on the 28th. A minimum temperature of -14.0°C was recorded at Dalwhinnie (Inverness-shire) on the 17th.  In the 24 hours ending at 0900 UTC on the 22nd, 127.6 mm of rain fell at Wet Sledale Reservoir (Cumbria). A wind gust of 86 knots (99 mph) was recorded at Brizlee Wood (Northumberland) on the 21st. A snow depth of 37cm was recorded at Altnaharra (Sutherland) at 0900 UTC on the 18th.
