Italy Places Nearly All Major Cities on Highest Heat Alert as Subtropical Heatwave Grips the Nation
Italy heatwave has escalated dramatically, with 25 of 27 major cities placed on red alert due to extreme heat.

Italy is placing nearly all of its major cities on the highest "red" heat alert level, as a subtropical heatwave originating from North Africa intensifies across the Mediterranean. By Monday, authorities expect 25 of the country's 27 major cities to operate under red alert conditions, with only two southern locations—Reggio Calabria and Messina—remaining at the secondary "amber" alert level.
Temperature Surge and Health Warnings
Italian health officials reported mid-30s Celsius temperatures across numerous regions on Saturday, with the extreme conditions expected to persist. The unprecedented alert expansion reflects a significant shift in risk assessment: authorities are now warning that even healthy and active individuals face potential heat-related dangers, not solely vulnerable populations such as the elderly, very young children, and those with chronic illnesses.
The health ministry has issued specific guidance for residents in affected areas. People are advised to avoid direct sun exposure during the peak heat hours between 11:00 and 18:00, remain indoors during these periods, and maintain consistent fluid intake. This cautious approach acknowledges the severity of the current meteorological conditions.
Broader European Crisis
Italy's heat emergency forms part of a wider European pattern, as France, Spain, Greece, and Portugal simultaneously battle devastating wildfires fueled by successive heatwaves. In France, approximately 2,500 residents were evacuated from the Var region after a previously contained fire reignited on Friday evening, though a major blaze in the Gironde region has been brought under control. Greece has seen hundreds of people, predominantly tourists, evacuated by sea from coastal areas threatened by multiple active fires. Spain has reported more than 200,000 hectares burned in recent months—roughly five times the seasonal average.
The extreme heat driving Italy's crisis stems from a strengthening subtropical anticyclone originating from North Africa, which is now consolidating its influence over Mediterranean weather patterns. This atmospheric system is expected to persist, maintaining dangerous conditions across the region.
