2025 Declared Hottest Year on Record in the UK

The British Meteorological Office has confirmed that 2025 was the hottest year recorded in the UK, with an average temperature of 10.09 degrees Celsius, breaking the previous record established in 2022.

This year also saw the highest number of sunshine hours since 1910, totaling 1,648 hours, marking a significant milestone in the country’s climate history.

Climate experts indicate that these trends are indicative of climate change driven by human activities.

All four seasons experienced above-average temperatures, with spring and summer recording their highest levels ever, while winter and autumn also exceeded historical norms.

Summer was characterized by four consecutive heatwaves and severe drought conditions, making spring 2025 the driest in over a century, leading to water usage restrictions in certain regions.

The Climate Change Advisory Committee has cautioned that the UK may encounter more severe climate events by mid-century, predicting an additional temperature rise of two degrees Celsius compared to pre-industrial levels, along with increased risks of drought, flooding, and sea-level rise of up to 25 centimeters, which could threaten coastal cities.

Consequently, 2025 presents the UK with significant climate challenges, necessitating urgent strategies to adapt to global warming and safeguard communities from its effects.
