The UK experienced a significantly milder January in 2026 compared to historical averages, according to new data released by the Met Office. The national average temperature for the month stood at 5.2°C, which is 1.5°C above the 30-year average for January (1991-2020). This trend was accompanied by higher-than-average rainfall across many parts of the country, leading to a largely unsettled start to the year.
Regionally, England recorded an average temperature of 5.6°C, with the South East seeing particular warmth and fewer frosty nights than usual. Rainfall across England was 115% of the long-term average, with the North West experiencing the highest precipitation, recording 145mm, 130% of its average. Conversely, some eastern parts of England saw rainfall closer to average.
Scotland also observed milder conditions, with an average temperature of 4.1°C. Rainfall was varied, with the Western Isles and parts of the Highlands receiving substantial amounts, exceeding 150% of their January average. Wind speeds across Scotland were generally moderate, though exposed coastal areas occasionally saw gusts reaching 50-60 mph during frontal passages.
Wales experienced an average January temperature of 5.0°C, slightly above its long-term average. Rainfall was notably higher, with the Welsh valleys and uplands receiving 160% of their typical January precipitation. This contributed to several days of localised flooding alerts, particularly in the mid and south Wales regions. The highest daily rainfall total in the UK was recorded in Snowdonia, at 78mm on January 18th.
Northern Ireland stood out as one of the wettest regions, recording an average of 170mm of rain, which is 180% of its January average, making it one of the wettest Januarys on record for the province. The average temperature in Northern Ireland was 4.8°C. The persistent rainfall led to challenges for agriculture and caused disruption to local transport networks on several occasions.
The Met Office noted that while the UK did not experience any significant extreme weather events such as widespread blizzards or severe gales, the combination of milder temperatures and increased rainfall is consistent with broader climate trends observed in recent years. The absence of prolonged cold snaps meant fewer instances of widespread ice and snow, particularly in urban areas.
