Northern Europe is grappling with an intense early summer heatwave this weekend, with authorities in the United Kingdom and France issuing health alerts as temperatures soar well above seasonal norms.The UK Met Office has forecasted highs of 34°C (93°F) in parts of eastern England on Saturday, marking a dramatic 12°C (22°F) increase above average for this time of year. The heat is part of a broader pattern affecting much of northern and western Europe, where unseasonably hot weather has settled in following a week of rising temperatures.In France, the heat is even more severe. Meteo France, the national weather service, has predicted temperatures will reach 38°C (100°F) in parts of the western and southern regions of the country — particularly dangerous for vulnerable populations.Heat Health Alerts Issued Across EnglandResponding to the escalating heat, the UK Health Security Agency (UKHSA) and the Met Office have jointly issued an amber heat health alert for the whole of England, in place through Monday morning. The alert specifically targets increased risks for older adults, especially those aged 65 and above, as well as individuals with chronic heart and lung conditions.“Heat can result in serious health outcomes across the population, especially for older adults or those with pre-existing health conditions,” said Dr. Agostinho Sousa, head of extreme event health protection at the UKHSA. “It is therefore important to check on friends, family and neighbors who are more vulnerable and to take sensible precautions while enjoying the sun.”Authorities are urging people to stay hydrated, avoid physical exertion during peak sunlight hours, and remain indoors where possible. The UK has increasingly been experiencing heatwaves in recent years, a trend that scientists say is likely to intensify due to climate change.France Warns: No One Is Immune to the HeatMeteo France has echoed similar concerns in its alerts for western and central France. The agency has cautioned that the current heatwave can pose health risks not only for vulnerable populations but also for healthy individuals, especially those exposed to prolonged sun or engaged in physical activity.“Everyone is at risk, even healthy people,” the agency warned, underlining the importance of recognizing the early signs of heat-related illnesses like heatstroke and dehydration.Real-Time Impact: Paris Air Show Attendees Seek ShadeThe impact of the scorching temperatures was visible earlier this week at the Paris Air Show, held at Le Bourget airport north of the French capital. Aviation enthusiasts and industry professionals attending the event were seen clustering in the shade of aircraft wings — including that of a Boeing 777 — to escape the heat, as the mercury hovered in the low 30s°C (mid-80s°F).The image has become symbolic of how Europe’s iconic summer events are being reshaped by climate extremes, with rising heat affecting not only public health but also tourism and outdoor activities.Cooler Weather Expected Next WeekAccording to British forecasters, Saturday is expected to mark the peak of the heatwave. Temperatures are forecast to dip slightly on Sunday, followed by a gradual return to more typical early-summer levels by midweek.While the immediate heat threat may ease in a few days, public health agencies are urging people not to drop their guard. “Heatwaves are becoming more frequent and more intense,” Dr. Sousa warned, “and our response must adapt accordingly.”
