Red Heat Warnings Return, Ice Cream Declares National Emergency

The United Kingdom is enduring one of its most severe heatwaves on record, with temperatures soaring to unprecedented levels, prompting red heat warnings, widespread disruption, and growing concerns over public health. The Met Office confirmed a provisional temperature of 36.7°C in Merryfield, Somerset, on Thursday, making it the hottest June day ever recorded in the UK and the highest temperature of 2026 so far. The exceptional heat has extended a rare red warning for extreme heat across London and parts of south-east England for a third consecutive day, with meteorologists warning of conditions that pose a serious risk to life. Record-Breaking Temperatures Across the UK Thursday saw all four nations of the UK record their highest temperatures of the year. The provisional figures include: England: 36.7°C at Merryfield, Somerset Wales: 35.6°C at Bute Park, Cardiff – the country's hottest June day on record Scotland: 31.2°C at Threave, Dumfries and Galloway Northern Ireland: 30°C at Castlederg, County Tyrone The new English record surpassed Wednesday's 36.1°C recorded in Gosport, Hampshire, which had already broken a June temperature record that had stood since 1976. Warmest June Nights Leave Millions Sleepless Alongside record daytime temperatures, Britain is also experiencing unusually warm nights. Cardiff recorded an overnight minimum of 23.5°C, officially making it Wales' warmest June night on record. Forecasters believe Thursday night may have broken even more overnight temperature records, with many areas in England and Wales expected to remain above 22–23°C throughout the night. Such conditions prevent buildings from cooling down naturally, increasing health risks, particularly for older people, children and those with underlying medical conditions. Red Heat Warning Continues The Met Office has warned that millions of people remain under a red extreme heat warning, with temperatures expected to reach 37–38°C in some areas on Friday. Officials warned the prolonged heat could lead to: Serious illness and increased risk to life. Widespread pressure on hospitals and emergency services. Power outages affecting heat-sensitive infrastructure. Significant disruption to transport networks. Changes to working hours and outdoor activities. Amber heat warnings remain in force across much of England and Wales, while thunderstorms are forecast in parts of Scotland, Northern Ireland and western Britain as cooler air gradually arrives. Heatwave Disrupts Daily Life The prolonged spell of extreme temperatures has already affected communities across the country. Several schools have temporarily closed due to unsafe classroom temperatures, while Kent has introduced a hosepipe ban amid growing pressure on water supplies. Rail services have also experienced delays as tracks and infrastructure struggle under the extreme heat. Healthcare services are facing increasing pressure as at least six NHS trusts have declared critical incidents. Reports indicate hospitals have experienced problems involving: IT systems Cancer treatment equipment Laboratory testing Medical scanners Meanwhile, London Ambulance Service reported its highest-ever number of life-threatening emergency calls, saying the surge was directly linked to the extreme temperatures affecting the capital. Tragedy During the Heatwave The dangerous conditions have also been linked to fatalities. South Wales Police confirmed that a 50-year-old man died after entering the water at Aberavon Beach on Wednesday afternoon. Authorities stated that his death is not being treated as suspicious, but the incident serves as another reminder of the dangers associated with extreme weather conditions. Scientists Point to Climate Change Meteorologists say the exceptional temperatures are being driven by a heat dome, a large area of high atmospheric pressure that traps hot air over western Europe for several days. Climate scientists say rising global temperatures are making these events increasingly intense and frequent. Dr. Akshay Deoras, Senior Research Scientist at the University of Reading, said climate change is adding extra heat to the atmosphere, making today's extreme temperatures significantly more severe than similar weather events experienced decades ago. According to the Met Office, the number of UK days exceeding 30°C between 2015 and 2024 was more than three times higher than the average recorded between 1961 and 1990, highlighting a clear warming trend. Relief Expected Soon Forecasters expect conditions to begin easing across western parts of the UK first, with Northern Ireland and Scotland already seeing cooler weather. However, eastern England is expected to remain extremely hot through Friday before temperatures gradually fall over the weekend. While thunderstorms may provide temporary relief in some regions, meteorologists warn they could also bring intense rainfall, lightning and localised flooding. A New Climate Reality This week's record-breaking heatwave has once again highlighted the growing challenges posed by extreme weather in the UK. From unprecedented daytime highs and tropical nights to mounting pressure on public services and infrastructure, experts say events once considered rare are becoming increasingly common as the climate continues to warm.
