2025 was Britain's hottest year on RECORD: Average UK temperature hit a balmy 10.09°C - as scientists say it's a 'clear demonstration of the impacts of climate change'
The Met Officehas confirmed that the average temperature in the UK last year was a balmy 10.09°C, which is 0.96°C above the long-term average.
It's official – 2025 was Britain's hottest year on record.
The Met Office has confirmed that the average temperature in the UK last year was a balmy 10.09°C, which is 0.96°C above the long–term average.
2025 now joins 2022 and 2023 in the top three warmest years since 1884.
According to the Met Office, this is a 'clear demonstration of the impacts of climate change'.
Dr Mark McCarthy, head of climate attribution at the Met Office, said: 'We're increasingly seeing UK temperatures break new ground in our changing climate, as demonstrated by a new highest UK mean temperature record just three years after the last record.
'This very warm year is in line with expected consequences of human–induced climate change.
'Although it doesn't mean every year will be the warmest on record, it is clear from our weather observations and climate models that human–induced global warming is impacting the UK's climate.'
While Britain has a reputation for its miserable weather, the Met Office has also confirmed that 2025 was the sunniest year on record.

Last year, the average temperature across the entire UK was 10.09°C.
Breaking this down by country, the average was 10.94°C in England, 8.63°C in Scotland, 10.29°C in Wales, and 10.09°C in Northern Ireland.
Both Spring and Summer 2025 were also the UK's warmest on record.
A total of four heatwaves were recorded between June and August, triggering hosepipe bans across parts of the country.
The highest temperature of the summer was 35.8°C (96.4°F), recorded at Faversham in Kent on July 1.
'While many will remember the long warm spring and summer of 2025, what has been noteworthy this year has been the consistent heat throughout the year, with every month except January and September warmer than average,' said Dr Emily Carlisle, a Met Office scientist.
'In the six months from March to August, every month was at least 1°C above the 1991–2020 average.
