The United Kingdom saw its record for the hottest June day broken for the third consecutive time on Friday, with the Met Office reporting that temperatures hit 37.3C in Suffolk. This new peak surpassed a 50-year-old record by more than a full degree, underscoring the severity of the heatwave currently impacting the nation.
The intense conditions have triggered widespread travel delays, forced the closure of schools, and led six NHS trusts to declare critical incidents due to being overwhelmed by patients. While the extreme heat is anticipated to subside over the weekend, a yellow weather warning for thunderstorms remains active for Scotland and parts of northern England.
Friday’s provisional high was recorded in the village of Santon Downham, following a peak of 36.7C in Merryfield, Somerset, on Thursday, which had itself exceeded the 36.1C recorded in Gosport, Hampshire, on Wednesday. Regional highs were also notable, with Wales reaching 35.1C in Flintshire, Scotland hitting 29.2C in Dumfries and Galloway, and Northern Ireland recording 25.6C in County Down.
All four UK nations recorded their highest temperatures of the year this week. In many areas of England and Wales, nighttime temperatures failed to drop below 20C, a phenomenon described by forecasters as tropical nights. Red warnings for extreme heat, which signal a population-wide health risk, were in effect for London and the south-east until 21:00 BST on Friday, alongside amber warnings for the south-west.
Health services have reported significant strain during the event. Dr. Hilary Williams of the Royal College of Physicians noted that high temperatures have compromised basic ward infrastructure, with reports of elderly care wards exceeding 30C and equipment like MRI scanners experiencing malfunctions. The London Ambulance Service reported a 50% increase in emergency calls, reaching record levels for life-threatening incidents on Wednesday, prompting the service to cancel non-essential training to bolster frontline staff.
Education was also heavily impacted, with over 600 schools in England closing on Friday, bringing the weekly total to more than 2,400 school closures across England and Wales. Major transport operators, including Avanti West Coast and Transport for London, warned of ongoing disruptions, while the AA reported a 14% increase in vehicle breakdown callouts. Several tourist sites, such as the Cutty Sark and the Royal Observatory, also closed their doors to the public.
In environmental and safety concerns, firefighters successfully contained a 200-hectare wildfire on Tintwistle Moor in Derbyshire. Tragically, the family of 13-year-old Hayden Jones-Powell confirmed his death by drowning while swimming in open water, prompting authorities to reiterate warnings about the dangers of such activities. Scientists have linked the increased frequency and intensity of these heatwaves to climate change, even as the current event is driven by a high-pressure heat dome trapping hot air over Western Europe.
