- Met Office issued an amber "extreme heat" warning covering London, Cambridge, Oxford, Birmingham, Nottingham, Lincoln, Sheffield and other areas from 9am to midnight Thursday, forecasting 37–38°C in the east, southeast and Midlands with risks to transport, infrastructure and vulnerable health.
- The UK Health Security Agency placed amber heat health alerts on all English regions except the north-east (yellow) through 9pm Friday, warning that hospital and care-home internal temperatures may exceed clinical-risk thresholds and raising risks of medicine-management failures and cold-water drowning.
- Environment Agency declared four more English regions in drought — East Midlands, Lincolnshire and Northamptonshire, Kent and East Sussex, and Solent and South Downs — bringing 71.3% of England into "flash drought" status alongside all of Wales after the driest July on record.
- Reservoir levels have fallen to 69%, 11.6% below the seasonal norm, while National Farmers' Union deputy president Paul Tompkins said farmers are completing the earliest harvest in 20 years with poor yields, livestock already on winter feed and growers struggling to access water.
- Firefighters entered a third day tackling a New Forest blaze that spread from a van fire on the A31 into heathland, while separate wildfires burned at Holme Fen peatland near Peterborough, Dunwich Heath in Suffolk, Headon Warren on the Isle of Wight, Llanwonno in south Wales and the Cairngorms national park.
- University of Reading hydrologist Hannah Cloke said only sustained rainfall over "months and even years" can end the drought, warning that baked soils will heighten flash-flooding risk when rain finally arrives, while the government said it would ease rules for on-farm reservoirs.
Why it matters: With 71.3% of England in flash drought and reservoir levels already 11.6% below seasonal norms, the 38°C Thursday peak will deepen pressure on farmers (earliest harvest in 20 years), the NHS (amber health alerts warning of hospital overheating) and water companies, and exposes how exposed UK infrastructure remains — the two new reservoirs ordered last year won't be ready until 2036 and 2040.
