The World Health Organization (WHO) has warned that Europe could face “more deadly weeks” as another powerful heatwave develops over the Atlantic. Temperatures in parts of Portugal and southern Spain are expected to reach as high as 43°C in the coming days. WHO Regional Director for Europe Hans Kluge urged governments to strengthen preparedness, noting that countries with established heat-health action plans responded more effectively during the recent extreme weather.

The previous heatwave, which swept across Europe between June 20 and June 28, is considered by experts to be the most severe ever recorded in the region. The intense heat disrupted power generation, damaged infrastructure, strained healthcare systems, and contributed to around 3,700 preliminary excess deaths in France, the Netherlands, and Belgium. Scientists have linked the record-breaking temperatures largely to climate change.

The WHO emphasized that vulnerable groups, including elderly people living alone, care home residents, and homeless individuals, continue to face the greatest risks during prolonged heat events. With fewer than half of the WHO’s European member states having comprehensive heat-health action plans, the organization is urging governments to improve emergency preparedness and build more resilient healthcare systems ahead of future heatwaves.
