Europe is facing an intensifying heatwave, with record-breaking temperatures and extreme heat alerts impacting several countries. The heat is shifting eastward after affecting western regions, prompting widespread disruptions and health warnings.
France has raised its health alert to the highest level, with some western areas anticipating severe thunderstorms and gusts of up to 110 km/h (68 mph) by Thursday afternoon. The first day of the Garorock festival in the Lot-et-Garonne region was canceled due to potential temperatures reaching 42C.
Climate change is a significant driver of rising global temperatures, with Europe warming at twice the global average, according to the Copernicus climate service. This trend is leading to more frequent and intense summer heatwaves, increased pressure on water resources, and a rise in wildfires. In 2022, over 1 million hectares burned across Europe, a record high, with Spain being particularly affected.
In Germany, overnight temperatures in Bad Bergzabern failed to drop below 26.2C on Wednesday night, equaling a national heat record from 2019. The German Weather Service (DWD) indicated that large parts of the country are experiencing "heat stress." The national train operator, Deutsche Bahn, is offering free ticket cancellations for travelers concerned about the extreme heat.
Luxembourg recorded its highest June temperature of 38.3C on Wednesday in Wormeldingen. A red alert for "extreme thermal stress" has been extended until Saturday night across the grand duchy.
Temperatures in the Czech Republic were in the high 30s on Thursday, with the Czech Hydrometeorological Institute forecasting a rise to up to 40C by the weekend. Czech Railways has advised passengers to consider postponing non-essential travel.
Italy is also experiencing high temperatures, which reached 32C inside Florence's Uffizi museum on Wednesday. The museum has temporarily halted ticket sales until June 28, admitting only visitors with prior bookings, as its air conditioning system struggles to cope with the heat and visitor numbers. The peak of the heat in Italy is expected on Monday, with 40C forecast for several northern regions, and nighttime temperatures potentially remaining above 29C.
Forecasters note a shift in temperature expectations, with a seasoned forecaster telling Italian media that forecasts of 34C are now welcomed. Officials in France have reported heat-related deaths, including among young people, highlighting the serious health risks associated with the extreme weather conditions.
