Italy is placing almost all of its major cities under red alert due to extreme temperatures.
Health authorities say 19 cities from north to south, including Rome, Milan, Venice and Naples, are already at the highest alert level. By Monday, almost all of the country's major cities are expected to be at the same risk level.
Temperatures reached around 35 degrees Celsius in many areas on Saturday, while authorities warn that the risk affects not only the most vulnerable groups, such as the elderly, young children and people with chronic diseases, but also healthy and active people.
According to the latest bulletin from the Italian Ministry of Health, published on Saturday, by Monday around 25 of the country's 27 main cities will be on red alert.
Only two cities are expected to remain at the second highest level, orange alert: Reggio Calabria, on the southern tip of the Italian peninsula, and Messina, on the island of Sicily.
The ministry has called on residents in affected areas to avoid exposure to heat and direct sunlight during the hottest hours, from 11:00 to 18:00, to stay in cool environments and to consume plenty of fluids.
The extreme temperatures are being caused by a subtropical anticyclone originating in North Africa, which is strengthening over the Mediterranean Sea.
Meanwhile, firefighters in Greece, France, Portugal and Spain continue to battle fires that have engulfed thousands of hectares of land.
In France, around 2,500 people were evacuated on Friday evening, July 31, in the southeastern Var region, after a fire that had been under control for several days reactivated, according to local authorities.
Meanwhile, a large fire in the southwestern Gironde region has been brought under control and around 200,000 evacuated residents have been able to return to their homes.
In Greece, hundreds of people, mostly tourists, have been evacuated by boat from a coastal town in Boeotia, surrounded by one of the many wildfires that have swept the country.
In Spain, more than 200,000 hectares of land have burned during 2026, about five times more than the average for this time of year, while in Portugal the burned areas are also above normal levels, according to European Union data.
Climate change is raising temperatures around the world. According to the Copernicus Climate Change Service, Europe is the continent warming the fastest, at a rate about twice the global average. This is leading to more summer heatwaves, greater pressure on Europe's water resources, and more frequent and intense wildfires.
