Met Office confirms summer 2025 was UK’s hottest on record
Dry soils and warm seas pushed UK to hottest summer on record
- The UK officially experienced its hottest summer on record in 2025, with a mean temperature of 16.10C between 1 June and 31 August.
- This new record surpasses the previous high of 15.76C set in 2018, making it the warmest summer since records began.
- The persistent warmth, driven by high-pressure systems, warm seas, and dry spring soils, led to back-to-back heatwaves, droughts, and wildfires across the country.
- The Met Office attributes the increasing baseline temperatures to climate change, projecting that future UK summers will become even hotter and drier.
- September is forecast to bring unsettled and often rainy conditions.
