Italy placed all 27 of its major cities under the highest heat alert on Thursday, marking the first time this year that the entire network has been under the red alert simultaneously, according to the Italian Health Ministry. The alerts stretch from Trieste in the northeast to Palermo in Sicily, signaling a health risk for the entire population, not only vulnerable groups. Authorities urged residents and tourists to avoid direct sunlight during the hottest hours, remain indoors where possible, and drink plenty of water .
The extreme heatwave has pushed temperatures above 40°C (104°F) in several Italian cities, with 25 of the 27 monitored cities already under red alert as of Tuesday. The remaining two, Messina in Sicily and Reggio Calabria, were projected to join them by Thursday. The ministry’s heatwave bulletin uses a four-tier system, with the red alert indicating emergency conditions for healthy adults, not just vulnerable groups .
The heatwave has also disrupted tourism and infrastructure. Rome extended evening opening hours at landmarks like the Colosseum and Pantheon, installed cooling mist fans at the Colosseum’s entrances, and added medical stations. The city also opened a free municipal “urban beach” along the Tiber River, where residents can cool off in swimming pools and shaded areas .
Meanwhile, the heatwave has fueled wildfires across Europe. In Serbia, firefighters are battling blazes in rugged mountain terrain, including the Ibar Gorge area and the Žarački Mountains, where over 150 hectares of forest have been affected. Strong winds have spread fires in the Deliblato Sands nature reserve, scorching around 500 hectares. One person died in a fire near Požarevac, and authorities have declared states of emergency in parts of Kovin and Bačka Palanka municipalities .
In France, wildfires have injured wildlife, with animals treated at the Aquitaine Wildlife Rescue Centre in Audenge after fires struck the Gironde region. The fires advanced quickly due to tinderbox conditions worsened by successive heatwaves since May .
The heatwave has also exposed vulnerabilities in energy systems. Poland shut down two coal-fired power plants due to critically low water levels in the Vistula River, losing approximately 1.3 GW of capacity. In Hungary, a nuclear power plant was temporarily shut down but is expected to resume operations as water levels rise .
Spain’s Agencia Estatal de Meteorología reported temperatures reaching 40°C in the Guadalquivir Valley and above 35°C in much of the country. The agency also warned of storms with hail and strong winds in eastern regions, including Castellón and Valencia .
