A historic, climate-driven heatwave has pushed hospitals across western Europe to the brink of capacity, forcing health authorities to mobilize emergency staff, issue public health warnings, and introduce extraordinary measures as millions endure dangerously high temperatures.
More than 101 million people across the region are experiencing temperatures above 35 degrees Celsius, with some areas recording highs exceeding 43 degrees. The prolonged “heat dome” has triggered a sharp increase in heat-related illnesses, overwhelming emergency departments and ambulance services while raising concerns over the resilience of healthcare systems amid increasingly frequent extreme weather events.
In France, authorities raised the national health alert to its highest level to strengthen hospital staffing and emergency response. Health officials reported that emergency room admissions for heat-related illnesses have quadrupled nationwide. In Paris alone, emergency services recorded 25 cardiac arrests within a single 24-hour period, more than double the city’s usual daily average of fewer than 10 cases.
The United Kingdom has also experienced unprecedented pressure on emergency services. The London Ambulance Service reported its highest number of life-threatening emergency calls in a single day, while several National Health Service (NHS) trusts, including Aneurin Bevan University Health Board and East Surrey Hospital, declared “critical incidents” after struggling to cope with rising patient numbers and aging hospital buildings lacking adequate air-conditioning.
In Spain, the SATSE nurses’ union warned that indoor temperatures in some hospitals have surpassed 30 degrees Celsius because of insufficient cooling infrastructure, creating unsafe working conditions for healthcare workers and increasing health risks for recovering patients.
The extreme temperatures have claimed multiple lives across the continent. In France, a three-year-old boy and two other toddlers died after being left inside overheated vehicles. Spain’s MoMo mortality monitoring system attributed 212 deaths to the heat over a four-day period, while Italy reported several fatalities involving agricultural and construction workers exposed to prolonged outdoor temperatures.
The heatwave has also shattered long-standing climate records. France recorded its hottest day on record with an average national temperature of 30.0 degrees Celsius, while the town of Pulluau registered a local high of 43.8 degrees Celsius. The United Kingdom recorded a new June temperature record of 36.4 degrees Celsius in Yeovilton, and Switzerland reached an unprecedented June high of 38.0 degrees Celsius in Basel.
Authorities have introduced emergency measures to reduce pressure on public services. In Paris, Police Prefect Patrice Faure imposed a temporary ban on public alcohol consumption and takeaway alcohol sales from Friday through Sunday, citing concerns that alcohol-related incidents could further burden already overstretched emergency departments.
The extreme weather has also disrupted transport and essential services. Italy experienced localized power outages in Milan and Turin as electricity demand surged due to widespread air-conditioning use. In Germany, rail operator Deutsche Bahn urged passengers to avoid non-essential travel after high temperatures caused rail tracks to deform and heightened the risk of wildfires along railway corridors.
Meteorologists say the high-pressure system responsible for the heatwave is expected to gradually shift eastward over the coming days. While temperatures are forecast to ease across parts of western Europe, Germany and several eastern European countries remain on high alert, with forecasts indicating temperatures could approach 40 degrees Celsius through the weekend.
Climate scientists have warned that such prolonged and intense heatwaves are becoming more frequent and severe as global temperatures continue to rise, increasing pressure on healthcare systems, infrastructure, and emergency services across Europe.
