Britain is enjoying its warmest stretch of spring on record this week, with temperatures peaking at 20.9°C in Gogerddan, west Wales—the highest so far in 2025. The unseasonable heat, driven by a stubborn high-pressure system, has bathed most of the UK in relentless sunshine, defying typical March norms by up to 6°C.
The warmth has been most pronounced in Scotland and Northern Ireland, where Friday could surpass their previous warmest day of the year. Meanwhile, the south and west of England have basked in the most consistent sunshine, while north-east England and southern Scotland contend with stubborn cloud cover, keeping highs capped at just 11–13°C.
Key Points
- ✅ 20.9°C in Gogerddan, Wales, marks the UK’s warmest day of 2025 so far
- ⚡ Scotland and Northern Ireland may break their own records by Friday
- 💡 North-east England and southern Scotland remain cooler with stubborn cloud cover
Despite the spring equinox arriving on Friday, the warmth shows no sign of abating. Meteorologists attribute the prolonged heat to a dominant high-pressure ridge anchored over the Atlantic, which has blocked incoming Atlantic weather systems and allowed temperatures to climb well above the seasonal average. Forecasters warn, however, that the reprieve is temporary.
📋 By The Numbers
- 6°C — Expected low in northern Scotland early next week
- 13°C — Projected high in south-east England by Monday
- 20.9°C — Recorded high in Gogerddan on Wednesday
From early next week, a sharp shift in wind direction will drag Arctic air across the UK, dragging temperatures below average and introducing a sharp drop in conditions. Northern and central regions will bear the brunt of the change, with wintry showers possible over higher ground in Scotland, northern England, and Wales. The Met Office has issued early warnings for icy patches and blustery winds, particularly in upland areas.
- Monday — Temperatures fall below average in Scotland and Northern Ireland
- Tuesday — Low-pressure system brings showers, some turning wintry over high ground
- Wednesday — Colder air settles in, with highs struggling to reach double digits in the north
The contrast between this week’s warmth and next week’s deep freeze underscores the volatility of Britain’s spring weather. While the current conditions feel unseasonably summery, climatologists note that spring has become the fastest-warming season in the UK, with March temperatures rising at nearly twice the rate of other months over the past decade.
💡 Pro Tip
Gardening enthusiasts should delay planting tender species until after mid-April, as the risk of late frosts remains high despite the current warmth.
For those hoping to extend the sunshine, the forecast offers a glimmer of hope. High pressure is expected to rebuild by the Easter weekend, bringing a return to settled conditions just as school holidays begin. Until then, Britons are advised to soak up the rare spring warmth while it lasts—because next week’s Arctic blast will be a stark reminder of the season’s unpredictability.
