January 2026 has been a month of unprecedented rainfall for many parts of the United Kingdom, according to newly released figures from the Met Office. Regions including Northern Ireland, the south-west and southern England, as well as the east of Scotland, have experienced one of the wettest Januarys in over a century, leading to heightened concerns about flooding and weather-related disruptions.
Unprecedented Rainfall Totals
Data reveals that Northern Ireland recorded a staggering 70% more rainfall than average, marking its wettest January in 149 years. In Cornwall, Culdrose saw rain levels soar to more than double its typical monthly average, while Aboyne in Aberdeenshire recorded nearly four times its expected total of 68.9mm. Despite this deluge, January also brought a relatively average amount of sunshine and temperatures that fell below the norm, a trend that is becoming increasingly rare as climate change alters weather patterns.
Conversely, areas in north-west England and western Scotland experienced below-average rainfall, with places like Altnaharra in Highland recording just 66mm—less than half of its typical January total. Aviemore also benefitted from a sheltered position behind the Cairngorm mountains, resulting in drier conditions.
Weather Patterns at Play
The unusual weather has been attributed to a persistent high-pressure system over Scandinavia, which has effectively blocked rain-bearing low-pressure systems from progressing across the UK. This phenomenon has led to a pattern of prevailing south-westerly winds in the southern regions and south-easterly winds impacting eastern Scotland. Regions exposed to these winds have consequently been drenched in heavy rainfall.
Flood Warnings and Further Risks
With the ground already saturated from January’s deluge, the Met Office has issued a yellow rain warning for south-west England, effective from 18:00 on Monday through 21:00 on Tuesday. Forecasts indicate widespread rainfall of 10-20mm, with localized areas, such as Dartmoor, potentially receiving up to 50mm. As of now, more than sixty flood warnings are in place, signalling an ongoing risk of flooding with the impending wet weather.
In addition to rain warnings, north-east Scotland is bracing for yellow snow warnings on Tuesday and Wednesday, predicting accumulations of 10-20cm above 200m, with smaller amounts at lower elevations. The potential for localised disruptions is a growing concern.
Weather forecasts suggest that the prevailing high-pressure system will linger over Scandinavia for the next fortnight, leading to a continuation of the current weather patterns. This could mean further heavy rain and localised flooding in southern England and eastern Scotland, alongside the possibility of hill snow.
The Irony of Water Restrictions
Interestingly, despite the widespread rainfall, parts of southern England are still under a hosepipe ban, highlighting the complexities of water management in a changing climate. While gardens and plants would typically require watering, the current weather conditions render such measures unnecessary.
Why it Matters
The record rainfall and subsequent flooding pose significant challenges not only to individual communities but also to infrastructure and emergency services across the UK. As climate change continues to intensify weather patterns, understanding these trends becomes crucial for effective planning and response strategies. The impact of such extreme weather is felt at multiple levels, from personal safety to economic stability, making it imperative for authorities to remain vigilant and proactive in managing future weather-related challenges.
