Belgium Heatwave: 1,222 Dead as Political Backlash Grows

Belgium recorded 1,222 excess deaths during a devastating heatwave between 18 and 29 June 2026 — a 39% spike in mortality that marks the highest daily death toll since the first wave of COVID-19 in 2020. The crisis has ignited a fierce political firestorm, with opposition leaders accusing the federal government of criminal inaction and demanding urgent structural reforms.

According to provisional data from the Risk Management Group (RMG) and Sciensano, the peak came on 27 June, when 572 deaths were registered in a single day. Of the total, 530 victims were aged 85 or older, but a significant 180 deaths occurred among people under 65 — challenging the assumption that only the very elderly are vulnerable to extreme heat. The figures, reported by VRT NWS, represent an unprecedented mortality event for a heatwave in Belgium.

A System Under Strain

The heatwave brought seven consecutive tropical days above 30°C, with exceptionally warm nights that offered little relief. The entire month of June was 3.1°C warmer than the long-term average, according to the Royal Meteorological Institute (KMI).

Belgium’s emergency infrastructure buckled under the strain. Wait times for the 112 emergency number surged to as long as 10 minutes during the peak weekend — compared to a normal average of 38 seconds. The 112 call centres received approximately 12,000 calls on Friday and Saturday and nearly 19,300 on Sunday, versus a daily average of roughly 6,000. Health Minister Frank Vandenbroucke acknowledged the failure, telling parliament: “The pressure on 112 was enormous. That’s 10 minutes, that’s way too long. That won’t do.”

Interior Minister Bernard Quintin offered a more measured assessment, noting that 47% of calls were answered within 20 seconds and 76% within 60 seconds, with an average wait time of 61 seconds over the weekend. However, he conceded that a 10-minute wait “is too long but was exceptional,” and pointed to ongoing recruitment challenges at emergency call centres.

Political Fury Erupts

The death toll has triggered a wave of political recrimination. Green party leader Aimen Horch delivered a blistering critique of the government’s response. “The government simply didn’t tackle it, except for the tips ‘drink some water’ and ‘take care of each other,’” Horch said, as reported by VRT NWS. He demanded a comprehensive emergency plan including public cooling stations, expanded access to swimming spots, and a mandatory air conditioning plan for residential care centres and schools.

Socialist Party (PS) leader Paul Magnette went further, accusing the authorities of abandoning citizens to their fate. “Zero measures taken by the federal government. Citizens have literally been abandoned to their fate,” Magnette wrote on X, as La Libre Belgique reported. “We’re talking about human lives,” he added, calling for swift action with more heatwaves forecast.

Health Minister Vandenbroucke, while acknowledging the 112 failures, struck a more cautious tone, describing the crisis as “a problem of society: elderly people, those living alone, and socially vulnerable people are the victims. And society must address that. You don’t do that with decrees and decisions.” He has asked the Risk Management Group to deliver recommendations by early next week.

A Continent in Crisis

Belgium’s tragedy is part of a broader European catastrophe. The June heatwave shattered temperature records across at least a dozen countries, from France and Germany to Slovakia, which recorded 41.3°C. Early estimates suggest between 17,000 and 25,000 heat-related deaths across Europe. Spain reported 1,028 heat-attributed deaths in June alone — more than double the figure from June 2025 — while the Netherlands estimated approximately 480 excess deaths.

Climate scientists at VITO, the Flemish Institute for Technological Research, calculated that the probability of a 12-day heatwave in Belgium is now nearly five times higher than in the 1980s. Such extreme events now occur once every seven years. The United Nations has warned of an intense El Niño expected between July and September 2026, raising fears of even more extreme weather to come.

The Air Conditioning Dilemma

The Green party’s demand for mandatory air conditioning in care homes has reignited a broader European debate. Only about 19% of European homes have air conditioning, compared to more than 90% in the United States, according to the International Energy Agency. Environmental concerns about energy consumption and refrigerant emissions now clash directly with the urgent public health need to protect vulnerable populations during increasingly frequent heatwaves.

Belgium’s challenges are compounded by its complex federal structure. Health policy is split between federal and regional governments, complicating coordinated responses. Climate Minister Jean-Luc Crucke’s attempt to convene an interfederal climate meeting was met with a boycott from both Flanders and Wallonia — a sign of the deep intergovernmental tensions that could hamper future preparedness.

What Comes Next

Vandenbroucke has requested RMG recommendations by early next week, and the National Crisis Centre has been asked to conduct an evaluation. But with more heatwaves forecast and structural issues — from understaffed emergency services to poorly equipped care homes — remaining unresolved, the political pressure shows no sign of abating.

The 1,222 figure is provisional. Final numbers from Sciensano are expected in the coming days and may be higher. For Belgium’s political leaders, the question is no longer whether another heatwave will come, but whether they will be ready when it does.
