A heatwave that has already caused dozens of deaths in western Europe is forecast to move east, bringing temperatures approaching 40°C to Germany and Poland, according to weather services and news reports as of June 27, 2026.
Britain, France, and Switzerland have experienced record-breaking temperatures in recent days. The UK Met Office reported that the UK saw its hottest day on record on June 26, with temperatures exceeding 40°C in some areas. In France, Météo-France confirmed that several departments were placed under red alert due to extreme heat, with temperatures reaching 42°C in parts of the country. Switzerland also recorded its highest June temperature, at 39.3°C in Geneva.
The German Weather Service (DWD) has issued warnings for the eastern states, predicting highs of up to 39°C on June 28 and 29. In Poland, the Institute of Meteorology and Water Management forecasts temperatures reaching 38°C in the coming days. Authorities in both countries have urged residents to stay hydrated, avoid strenuous activity during peak heat, and check on vulnerable neighbors.
The heatwave has been linked to at least 30 deaths in France, Spain, and Italy, according to local health authorities. Hospitals have reported an increase in heat-related illnesses, including heatstroke and dehydration. Climate scientists attribute the extreme event to a persistent high-pressure system over central Europe, exacerbated by climate change.
As the heatwave moves east, relief is not expected until early July, when cooler Atlantic air is forecast to arrive. Emergency services remain on high alert across the affected regions.
