Health and emergency services across Europe remain on high alert as an intense heatwave sweeps the continent, pushing temperatures well above seasonal norms and triggering a series of public-safety measures.
From Britain and France to Germany, Italy, Austria and Serbia, large swaths of Europe have experienced record-breaking heat as a bulge of hot air stalled over the region. Authorities and scientists describe the event as the most severe of its kind recorded in the region studied, and they warn of continued pressure on health systems and infrastructure even where temperatures begin to ease.
France has been particularly hard hit. Officials have linked at least 55 deaths to the heatwave, with Paris reaching 40.9 degrees Celsius on Wednesday. In response to the emergency conditions, French authorities announced a ban on drinking alcohol in public on Friday - a day when the national soccer team was due to play Norway in Boston in the World Cup - and state-owned electricity company EDF pledged to spend 80 million on cooling systems for schools, kindergartens and day-care centres.
Hospitals and emergency departments reported a surge in calls and treatments. Wilfrid Samut, spokesperson for the Association of Emergency Room Doctors of France, said institutions were not prepared for the scale of the heatwave and described the toll on medical staff as severe, saying "the impact on the mental health of healthcare workers is enormous" and calling conditions "apocalyptic."
Authorities across the continent took a range of precautionary measures. In Paris, police asked organisers of major events, including the Solidays music festival, to cancel. Organisers of the city's Pride festival said they would reschedule. Cultural landmarks in several countries closed their doors and farming operations reported heat-related damage.
Transport infrastructure showed signs of distress. In eastern Germany the surface of the A2 motorway buckled and ruptured across multiple lanes on Thursday evening, damaging up to 30 vehicles and leaving two people with minor injuries, according to reporting by the BZ newspaper. The damage forced a closure of the highway while repairs and safety checks are carried out.
Weather services issued unusually severe alerts in several countries. Britainxtended a Met Office red heat alert into Friday for a wide area of southern England - the first time such warnings have been in place for three consecutive days. The Netherlands saw a rare 'code red' extreme heat alert covering almost the entire country, prompting many schools to close as temperatures up to 40 degrees Celsius were expected.
In Serbia authorities raised an amber alert with forecasts of around 36 degrees Celsius, and public messaging in Belgrade urged residents to stay indoors during the hottest hours and to maintain hydration. Across Britain, consumer behaviour shifted quickly - fans sold out in many shops - and Asian air conditioning manufacturers reported a surge in European sales.
Data cited from the International Energy Agency, affiliated with the OECD and issued in July 2025, indicate that household ownership of air conditioning across Europe remains relatively low at about 20 percent, a factor that may leave many households vulnerable during prolonged heat.
Meteorologists say the heatwave owes its persistence to a weather pattern known as an Omega block, which traps an expansive mass of hot air over affected regions while cooler air circulates around its edges. According to analysis by the Reuters Climate Monitor, temperatures have been pushed as much as 18 degrees Celsius above seasonal averages in places.
Climate scientists and attribution groups emphasize the role of human-caused warming in intensifying this event. The World Weather Attribution group said that over the region it studied, the current heatwave is the most severe on record. Scientists also stated the heatwave would have been "virtually impossible" without human-driven climate change and that the particularly high night-time temperatures this week are now roughly 100 times more likely than they would have been two decades ago.
While temperatures appear to have passed their peak in France and Britain, where June records were broken, forecasters said the heat could grow more intense in Italy into the weekend, with meteorological services expecting the summer's first readings of 40 degrees Celsius or higher in parts of the country.
Officials warned that even as daytime highs moderate in some areas, the danger remains for further casualties and additional stress on emergency services. The combination of higher-than-average daily temperatures, stifling overnight conditions and limited air conditioning penetration in many parts of Europe presents a continued public health challenge.
Key points
- At least 55 heat-linked deaths reported in France; Paris recorded 40.9 C on Wednesday and public alcohol consumption was banned on a major match day.
- Critical infrastructure was affected - the A2 motorway in eastern Germany buckled, damaging up to 30 vehicles and injuring two people; transport networks and cultural events were disrupted.
- Climate analysis attributes the extreme intensity to an Omega block pattern and human-caused climate change, which scientists say made this event far more likely than in the recent past.
Risks and uncertainties
- Further casualties and medical demand - despite some cooling in parts of Europe, authorities expect continued health impacts and strain on hospitals and emergency services.
- Infrastructure and mobility disruptions - heat-related damage to roads and transport links could cause prolonged closures and economic impacts for affected regions.
- Energy and public-cooling capacity limits - with relatively low air conditioning ownership in Europe and rising demand for cooling, power systems and public services may face pressure.
As the immediate emergency response continues, officials and scientists underline the need for vigilance and resources to protect vulnerable populations while managing pressure on hospitals, transport and energy systems.
