ITALY PERSPECTIVE

Rome, June 20, 2026. The heat wave battering Europe since early this week is striking Italy with particular intensity. Desert winds from the Sahara are pushing a mass of scorching air toward the central-north portion of the Peninsula, where thermometers could exceed 40 degrees Celsius this weekend. Milan, Bologna, and Florence are identified as the most exposed zones, according to meteorologists from ilmeteo.it, who report temperatures potentially 10 degrees Celsius above typical seasonal averages across a large portion of the country.

The Health Ministry was quick to respond. It issued a red alert — the maximum emergency level — for Bologna, Florence, Turin, Perugia, and Brescia beginning Saturday. Rome, Milan, Bolzano, Verona, Frosinone, Latina, and Rieti are placed under orange alert, while nearly all other major cities face preventive yellow alert classification. Only Genoa, Cagliari, and Campobasso escape any risk classification on Saturday. Sunday, the red zone is expected to expand to Milan, Bolzano, and Rieti, with several additional cities escalating to orange status — Venice, Trieste, Pescara, and Viterbo among them.

The heat does not limit itself to daytime hours. In many zones, nighttime temperatures are not expected to drop below 20 degrees Celsius, the threshold at which meteorologists speak of "notti tropicali" — tropical nights. This phenomenon heightens health risks, particularly for elderly persons, young children, and those under medical treatment. Beginning Monday, June 22, the Health Ministry will activate emergency number 1500, dedicated to heat-stroke prevention guidance. Distributed recommendations include: avoiding any outdoor activity between 11 a.m. and 6 p.m., hydrating the body before even sensing thirst, and adapting home environments by blocking south-facing windows.

This heat wave sits within a documented climate disruption context. Milan recorded its warmest spring since 1897: between March and May, average temperatures reached 17.1 degrees Celsius, or 2.3 degrees above the 1991-2020 norm and 3.6 degrees above the 1961-1990 reference. The European climate service Copernicus confirms Italy experienced its second-warmest spring on record, following a series of abnormally elevated months. For many Europeans, the current heat wave is already the second of summer, and scientists emphasize that human-driven climate change intensifies the frequency and severity of such episodes. "When heat waves occur, they are all the more intense," summarized Alex Deakin, meteorologist from the British Met Office, cited by AFP. Alpine zones could also be touched by brief but violent thermal storms, a direct consequence of ascending warm air masses.
