From June 1 to Aug. 25, Britain’s mean temperature stood at 16.13 degrees Celsius.
Data from Britain’s Met Office indicates that the summer of 2025 is on track to be the warmest on record since 1884, with a mean temperature of 16.13 degrees Celsius from June 1 to August 25. This temperature surpasses the previous record of 15.76 degrees, set in 2018, by 1.54 degrees above the long-term average, reports 24brussels.
The new statistics would displace 2018 from the top position in the historical rankings, with the summer of 1976 also being pushed out of the top five warmest summers recorded. According to Met Office scientist Emily Carlisle, barring a significant drop in temperatures, the 2025 record is poised to be surpassed.
“Of course, there are still a few days left of meteorological summer to go, but it’s very unlikely anything will stop summer 2025 from being the warmest on record,” Carlisle stated. The forecast suggests that a 4-degree drop below the average for the remainder of August is improbable.
This summer mirrors the heat of 1976, which is remembered for its prolonged heatwave, yet 2025 stands out for the ongoing consistency of warmth, driven by a combination of factors such as prolonged dry conditions, high-pressure systems, and notably warm sea temperatures.
Temperature records have shown significant increases, particularly in minimum temperatures. Britain’s mean summer temperature from 1991 to 2020 was 14.59 degrees Celsius, which indicates a rise of over 0.8 degrees compared to the period from 1961 to 1990.
Future projections signal that Britain will experience hotter and drier summers, a trend already observable in recent years. Climate experts warn that climate change will continually elevate baseline temperatures, transforming previously normal years into record-setting ones.
This summer’s four heatwaves, while potentially viewed as merely warm weather in the past, now underscore the pressing reality of global warming. The cumulative impact of these developments continues to reshape Britain’s climate narrative.
