Britain recorded its hottest year on record in 2025 - the average annual

Britain experienced its hottest and sunniest year ever recorded in 2025, surpassing the previous record of 2022, as persistent high pressure systems and unusually warm seas boosted temperatures.

The Met Office said the average annual temperature was 10.09 degrees Celsius, exceeding the 2022 average of 10.03 degrees Celsius and marking only the second year since records began in 1884 that the average annual temperature has exceeded 10 degrees Celsius.

The reading also placed four of the last five years in the top five warmest years since 1884, an indicator of how quickly the climate is changing, the Met Office said last month when it first signalled the possibility of a new record.

"While this does not mean that every year will be the warmest ever recorded, it is clear from our weather observations and climate models that human-caused global warming is affecting the UK's climate," the Met Office said.

All of the 10 warmest years have occurred in the last two decades and since the start of the 21st century, a record has been set for the average annual temperature in the UK six times.

The data is consistent with global trends, with the World Meteorological Organization saying in 2025 that the last 10 years have been the warmest since records began.

The European Union's Copernicus Climate Change Service (C3S) has predicted that 2025 will be the world's second or third warmest year ever recorded in modern records, as extreme weather continued to hit regions across the globe last year.

Globally, 2024 was the hottest year ever recorded, as well as the warmest for Europe, the fastest-warming continent on the planet.
