Italy's Ministry of Health escalated its highest-level heat warnings to 16 cities on Thursday, with Milan joining the red-alert roster, and officials forecast the number will climb to 19 by Saturday as Ancona, Civitavecchia and Catania are added.
The red status — level three on Italy's alert scale — signals a weather emergency posing high risk to population health. Turin endured level 2 or 3 alerts on 23 days between 25 May and 30 June, or 63% of the period. Authorities said June 2026 was the second-hottest on record in Italy.
Heat-linked excess mortality has been limited to roughly 3% and confined to those aged over 85 in Italy, though heat waves have killed nearly 10,000 people across five European countries so far this summer, after Italy’s third heat wave of the season peaked Thursday.
