WHO Warns of 'More Deadly Weeks' as Europe's Heat Emergency Persists

Verified key facts

• On 7 July 2026 the WHO warned Europe could face 'more deadly weeks' as another heatwave built over the Atlantic.
• France, the Netherlands and Belgium recorded around 3,700 excess deaths during the 20-28 June heatwave, with figures preliminary.
• Fewer than half of WHO Europe member states had a heat-health action plan in place.
• An emergency call brought together 41 member states, the European Commission and civil society groups.

A blunt warning from Geneva and beyond

The World Health Organization has issued a stark warning about Europe's summer. On 7 July 2026 it said the region could face more deadly weeks ahead. Another intense heatwave was forming over the Atlantic.

The WHO Regional Office for Europe framed the moment as an emergency. Its statement warned that the worst health impacts of the season might not be over. Reuters coverage carried the warning widely.

Forecasts underlined the concern. Portugal and southern Spain were expected to reach 43C. France and the Benelux countries were bracing for another heat surge.

The toll of the June heatwave

The warning followed an already deadly stretch. The WHO described the 20-28 June heatwave as the most severe recorded in Europe. It disrupted power generation, damaged infrastructure and overwhelmed healthcare systems.

The human cost was significant. France, the Netherlands and Belgium recorded around 3,700 excess deaths during that period. Authorities stressed the numbers were preliminary and could rise.

Older people bore much of the burden. Earlier national figures showed the majority of heat-related deaths among people aged 65 and over. Heat stress is especially dangerous for those with existing health conditions.

A gap in preparedness

The WHO drew a clear link between planning and survival. It said countries with heat-health action plans responded more quickly. Those plans helped better protect their populations during the June heatwave.

The problem is that many countries lack them. According to the WHO, fewer than half of its European member states had such a plan in place. That gap leaves populations more exposed to each new wave of heat.

Certain groups are being missed even where plans exist. The WHO noted that care home residents, homeless people and socially isolated older adults were not being reached consistently. These are among the most vulnerable to extreme heat.

• Around 3,700 excess deaths in France, the Netherlands and Belgium in late June
• Fewer than half of WHO Europe states have a heat-health action plan
• Portugal and southern Spain forecast to reach 43C in early July
• Vulnerable groups including isolated older adults still not reliably reached

A coordinated emergency response

The scale of the threat prompted collective action. The WHO said an emergency call on extreme heat brought together representatives from 41 member states. The European Commission and several civil society groups also took part.

Euronews reported that the WHO judged Europe's readiness for extreme heat to fall short. The message was that heatwaves are no longer rare events. They are becoming a recurring public health emergency.

The June-July pattern in 2026 reinforced that view. A third UK heatwave began on 4 July. The UK Health Security Agency extended heat-health alerts across England, keeping them in force until 12 July.

Living with recurring extreme heat

Public health advice during heatwaves centres on general precautions. Staying hydrated, keeping cool and checking on vulnerable neighbours are standard messages. These are broad guidance points rather than individual medical instructions.

People with health conditions face particular risk in extreme heat. They are generally advised to follow guidance from national health authorities. Anyone feeling unwell in the heat should seek help from a healthcare professional.

The wider policy question is structural. The WHO's framing suggests heat planning must become routine, not exceptional. Building shade, cooling centres and outreach to isolated people are among the measures under discussion.

For now, the immediate concern is the weeks still to come. The WHO's warning was explicit that the danger had not passed. As temperatures climbed again, its message to governments was to prepare rather than wait.
