Europe is enduring an unprecedented sweltering summer in 2026, as a relentless heat dome dominates most parts of the continent and shatters long-standing seasonal temperature records. Southern, western and central European countries are the worst-hit regions, with widespread extreme heat triggering urgent public health alerts.
Spain, France and Italy registered peak temperatures exceeding 44°C in late June. Nordic and Baltic nations, rarely affected by extreme heat, also saw record-high readings, with Denmark hitting 37°C. Official data shows the intense heat caused over 10,000 excess deaths across 27 European countries in late June, mostly among elderly residents aged 65 and above.
Many regions issued top-level red heat warnings, forcing temporary school closures, adjusted public transport schedules and suspended outdoor work. Medical systems are under huge strain due to surging heat-related illnesses. Meteorologists attribute the prolonged heatwave to warm African air currents and climate change, warning that extreme summer heat in Europe will become more frequent in the coming years.
