Over 1,300 excess deaths have been recorded across Europe since June 21 due to the record-breaking heatwave currently gripping the continent, according to the World Health Organization (WHO). The death toll—confirmed by preliminary data from 35 countries—underscores the severe public health crisis unfolding as temperatures exceed 40°C (104°F) in multiple regions, including southern and western Europe. Health officials warn that the true figure may be higher as reporting delays persist in some countries.
The WHO’s warning comes as Europe experiences its hottest summer in decades, with prolonged heatwaves breaking temperature records in Spain, Portugal, France, Italy, and the Balkans. Meteorologists attribute the extreme conditions to a combination of climate change and a persistent high-pressure system trapping scorching air over the region. The European Centre for Disease Prevention and Control (ECDC) has classified the heatwave as a “major public health threat,” particularly for vulnerable populations such as the elderly, children, and those with pre-existing health conditions.
While the WHO’s preliminary figure of 1,300 excess deaths is based on data from June 21 to July 20, experts caution that the actual toll could rise as heat-related illnesses—including heatstroke, cardiovascular strain, and respiratory failures—take days or weeks to manifest. Spain alone has reported over 4,700 excess deaths since June 1, according to its national statistics institute, though officials note that some deaths may be attributed to indirect factors such as delayed medical care during the heatwave.
Why Are Excess Deaths Rising During Europe’s Heatwave?
Excess deaths occur when the number of fatalities exceeds the historical average for the same period. During heatwaves, the primary causes include:
- Heatstroke and dehydration: The human body struggles to regulate temperature above 35°C (95°F), leading to organ failure in extreme cases. The WHO reports that heatstroke deaths in Europe surged by 30% compared to the same period last year.
- Cardiovascular strain: High temperatures increase blood pressure and heart rate, triggering heart attacks or strokes. Data from the European Centre for Disease Prevention and Control (ECDC) shows a 20% rise in hospitalizations for heat-related cardiac events.
- Respiratory failures: Poor air quality—exacerbated by wildfires and ozone pollution—worsens conditions for those with asthma or COPD. Italy’s national health agency has recorded a 15% increase in respiratory-related deaths in affected regions.
- Indirect factors: Heatwaves disrupt healthcare systems, delay emergency responses, and increase social isolation among vulnerable groups. The WHO highlights that over 60% of excess deaths occur in individuals aged 65 and older.
The current heatwave has also strained healthcare systems, with hospitals in southern Europe reporting overflowing emergency departments. In Portugal, for example, the national health service has activated emergency protocols, including mobile cooling units and extended operating hours for heat-related cases. Meanwhile, France’s health ministry has issued red alerts in 12 departments, advising residents to avoid outdoor activities during peak heat hours.
How Do Europe’s Excess Deaths Compare to Past Heatwaves?
The 2024 heatwave’s death toll already surpasses that of the deadly 2003 European heatwave, which killed an estimated 70,000 people across the continent. However, differences in reporting methods and population growth make direct comparisons difficult. Below is a breakdown of recent heatwave impacts:

| Year | Heatwave Period | Estimated Excess Deaths | Most Affected Countries | Key Factor |
|---|---|---|---|---|
| 2003 | August 1–15 | 70,000+ | France, Italy, Spain, Portugal | Poor public awareness and limited cooling infrastructure |
| 2010 | June–August | 15,000+ | Russia, France, UK | Prolonged high-pressure system (“Russian Heatwave”) |
| 2015 | June–August | 5,000+ | Spain, Portugal, Italy | Early-season heatwave with poor preparedness |
| 2022 | June–September | 61,000+ | UK, Spain, France, Germany | Record-breaking temperatures and wildfires |
| 2024 (to date) | June 21–July 20 | 1,300+ (and rising) | Spain, Portugal, Italy, Balkans | Early onset and prolonged duration |
Unlike past heatwaves, the 2024 crisis has occurred earlier in the season, catching some regions off guard. Meteorologists predict that temperatures will remain elevated through August, raising concerns about further spikes in excess deaths. The Copernicus Climate Change Service reports that July 2024 is on track to become the hottest month ever recorded globally, with Europe experiencing anomalies of up to 10°C above average.
What Are Governments and Health Agencies Doing to Respond?
European governments and health agencies have implemented a mix of emergency measures to mitigate the crisis:
- Cooling centers: Over 1,200 cooling centers have been opened across Spain, Portugal, and Italy, providing respite for homeless individuals and the elderly. In Madrid, city officials have converted public libraries and community centers into temporary relief hubs.
- Public health alerts: France, Spain, and Italy have issued national heatwave plans, including restrictions on outdoor work during peak hours and mandatory hydration breaks for workers.
- Wildfire prevention: Portugal and Spain have deployed over 10,000 firefighters to contain wildfires sparked by the heat. The European Union’s European Green Deal has allocated €1 billion for forest management and early warning systems.
- Vaccination campaigns: Health authorities in southern Europe are accelerating vaccination drives for pneumonia and flu, as heatwaves weaken immune systems and increase susceptibility to respiratory infections.
Despite these efforts, critics argue that long-term solutions—such as improving urban heat resilience, expanding public cooling infrastructure, and addressing climate change—remain insufficient. The WHO’s regional director for Europe, Dr. Hans Kluge, emphasized that “heatwaves are no longer rare events but a recurring threat that demands sustained action.”
“The data is clear: heatwaves kill. Without urgent climate action and adaptive measures, we will see these numbers rise every year.”
— Dr. Hans Kluge, WHO Regional Director for Europe
Who Is Most at Risk During the Heatwave?
While the heatwave affects the entire population, certain groups face disproportionate risks:
- Elderly individuals (65+): Account for over 60% of heat-related deaths. Many live alone and may lack air conditioning or social support.
- Outdoor workers: Construction, agricultural, and delivery workers face heightened exposure. The European Agency for Safety and Health at Work reports that heat stress contributes to 2,500 workplace deaths annually.
- Children and infants: Their bodies regulate temperature less efficiently. Heatwaves increase risks of heat exhaustion and sudden infant death syndrome (SIDS).
- People with chronic illnesses: Those with diabetes, heart disease, or mental health conditions are particularly vulnerable. The WHO advises them to stay indoors during the hottest hours (11 AM–4 PM).
- Homeless populations: Lack of access to shelter and hydration puts them at extreme risk. Cities like Athens and Rome have distributed water bottles and opened night shelters.
To protect vulnerable groups, the WHO recommends:
- Checking on neighbors, especially the elderly.
- Avoiding strenuous activity during peak heat.
- Staying hydrated (drinking water regularly, even without thirst).
- Using fans, wet cloths, or cool showers to lower body temperature.
- Seeking medical help immediately for symptoms like dizziness, nausea, or confusion.
What Happens Next? Monitoring and Long-Term Risks
The WHO and ECDC will continue updating excess death figures as more data becomes available. Meteorologists predict that the heatwave will persist through early August, with possible extensions into September in some regions. Meanwhile, policymakers are under pressure to accelerate climate adaptation strategies, including:

- Urban greening: Expanding parks, green roofs, and tree-lined streets to reduce the “urban heat island” effect.
- Heat-action plans: Mandating early warning systems and public cooling infrastructure in all EU member states.
- Climate resilience funding: The EU’s Adaptation Strategy 2021–2030 aims to mobilize €100 billion for heatwave preparedness by 2030.
The next critical checkpoint will be the WHO European Regional Committee meeting in September, where health ministers are expected to discuss formalizing heatwave response protocols across the continent. In the meantime, residents in affected areas are urged to monitor official advisories:
As the heatwave continues, the human toll serves as a stark reminder of the urgent need for global action on climate change. For now, the focus remains on immediate relief—saving lives in the face of Europe’s hottest summer in recorded history.
