The UK Met Office has confirmed that 2025 was the warmest and one of the sunniest years in the country's recorded history. According to the agency, the record reflects the clear impact of human-induced climate change. Based on data dating back to 1884, 2025 now ranks among the top three warmest years alongside 2022 and 2023, with an average annual temperature of 10.09 degrees Celsius. It was only the second time the UK’s annual average temperature exceeded 10 degrees Celsius, the first being in 2022.

The Met Office noted that four of the five warmest years since 1884 have occurred within the past five years, and all ten warmest years have been recorded in the last two decades. In addition to temperature, 2025 also set a new record for sunshine, with 1,648.5 hours of sunlight—the highest since records began in 1910 and 61.4 hours more than the previous record set in 2003.

Mark McCarthy, head of the Met Office’s climate attribution division, said the findings align with expectations from human-driven climate change and that global warming continues to influence the UK’s climate.
