UK Records Hottest Day of the Year as Fifth Summer Heatwave Reaches Peak

Europe is experiencing a severe heatwave, with temperatures on the continent surpassing 40C at the peak of the summer's fifth heatwave. The UK has recorded its hottest day of the year so far, with a provisional temperature of 38.1C in southern England. The heatwave has been particularly severe in southern England, where an amber extreme weather warning was issued on Thursday. This warning applies to areas including London, the Midlands, north-west England, south-west England, and parts of Yorkshire and Humber. An extreme heat alert warning of significant impacts on health and social care services is also in place across the whole of England until 9pm on Friday. The Met Office has stated that this summer is on course to be the UK's hottest since records began. With 2026 likely to be the first year in which the country has recorded four separate days with temperatures of 36C or above, the UK is experiencing a prolonged period of extreme heat. The heatwave has also had a significant impact on fire risk, with Spain breaking its burned area record for this time of year. In France, the area burned had already surpassed that of any full year on record by the third week of July. Firefighters in the UK are continuing to tackle a blaze in the New Forest in Hampshire, while in the West Midlands, at least six homes were damaged and four people were taken to hospital for treatment due to an extensive grassfire near Stourbridge golf course. The heatwave has also had a significant impact on water resources, with nearly three-quarters of England and the whole of Wales in drought. This has put pressure on water resources for households, agriculture, and the environment. In mainland Europe, record-low water flows on the Danube have deprived thermal power plants of cooling water and forced some to reduce output. The human-driven climate crisis is primarily the result of burning fossil fuels, which releases greenhouse gases that trap heat, raising temperatures. The extra heat alters the planet's water cycle and energy balance, making extreme events such as heatwaves, heavy downpours, and severe drought significantly more frequent and intense. Doctors consider heat a "silent killer" because it greatly increases mortality rates while only occasionally being listed as the direct cause of death. In Germany, where meteorologists have issued heat warnings for a swathe of the west of the country for Friday, public health officials estimate that 12,500 people have died as a result of the heat so far this summer. NHS staff working in A&E departments across England have experienced their busiest summer ever, health leaders said. The Royal College of Nursing said its members were working in inhumane conditions, "dripping with sweat from head to toe" during the record-breaking heat. The RCN became the latest union to speak of unsafe working conditions for many members in hospital wards and care homes as the number of days of 30C-plus heat in the UK reached a record 35. The water industry regulator, Ofwat, said it would allow water companies in England and Wales to increase bills to spend £3.4bn more than planned to meet supply demands, including for the building of new homes and datacentres. This decision has been made in light of the severe water scarcity in many areas of the UK, which has been exacerbated by the prolonged heatwave. The heatwave is a stark reminder of the need for urgent action to address the human-driven climate crisis. As Julia King, the peer who chairs the adaptation work of the Climate Change Committee, an independent advisory body to the UK government, has said, extreme weather "gets worse from here" until net zero is reached.
