The year 2025 has been confirmed as a landmark year for the United Kingdom’s climate, breaking two long-standing records. According to provisional data released by the Met Office, it was both the warmest and sunniest year since UK records began. Scientists say these findings provide further evidence of a continuing warming trend linked to climate change.
Average temperatures across the UK reached 10.09 °C in 2025, making it the warmest year on record since measurements started in 1884. This record places 2025 ahead of previous high-temperature years such as 2022 and 2023. The Met Office explained that long-term climate warming has increased the likelihood of record-breaking temperatures, meaning years like 2025 are becoming more common rather than exceptional.
Sunshine levels were also unusually high throughout the year. The UK recorded a total of 1,648.5 hours of sunshine, making 2025 the sunniest year since sunshine records began in 1910. This surpassed the previous record set in 2003 by more than 60 hours. Many parts of the country experienced extended periods of clear skies, particularly during spring and summer, which contributed to the record total.
Rainfall patterns in 2025 were more mixed. Early in the year, dry conditions dominated with spring being the driest since 1974 in some regions. However, wetter weather later in the year balanced rainfall levels, resulting in an overall annual total close to the long-term UK average. Despite this, the uneven distribution of rainfall caused local challenges, particularly for agriculture and water resources.
Climate experts highlighted that recent records reflect a broader trend rather than isolated events. Four of the UK’s five warmest years have now occurred within the last decade, underlining the influence of global climate change. While individual years will still vary due to natural weather patterns, scientists warn that rising temperatures and more extreme conditions are expected to continue unless greenhouse gas emissions are reduced.
