Italy’s National Health Service has placed almost all major cities on the highest “red” risk level for heat, following a sudden surge that has seen temperatures soar into the mid‑30s Celsius across the country.

The ministry’s latest bulletin announced that on Monday 25 of the 27 major cities would be on a red alert, with only Reggio Calabria and Messina remaining on the secondary “amber” level. The hot‑weather strain is affecting cities from Rome and Milan to Venice, Naples, and Turin.

Health officials note that the heat is dangerous even for otherwise fit and active individuals, not just older adults, children, or those with chronic illnesses. They recommend staying indoors during peak hours (11:00–18:00), avoiding direct sunlight, and drinking plenty of fluids.

The extreme temperatures are attributed to a strengthening subtropical anticyclone over the Mediterranean, fed by hot winds originating from North Africa. This weather pattern is a common cause of the intensive heatwaves that have preceded recent wildfires across Europe.

Meanwhile, across the continent Greece, France, Portugal, and Spain remain in active firefighting mode as blazes force the evacuation of more than twenty‑five hundred people in France’s Var region and fuel the spread of several thousand hectares of burned land in Spain and Portugal.

Climate research shows Europe’s warming rate is about twice the global average, leading to more prolonged heat events, higher pressure on water supplies, and larger forests catching fire in summer. The current heatwave underscores the urgent need for heat‑wave preparedness measures alongside broader climate‑adaptation strategies.
