Italy’s Ministry of Health activated its Level-3 (‘bollino rosso’) heat-wave protocol for 19 major cities on 29 July 2026 as temperatures spiked above 40 °C. The alert, valid through 2 August, triggers mandatory availability of medical teams at airports and major rail hubs and authorises local prefects to impose time-of-day road restrictions on heavy vehicles transporting hazardous goods. At Rome-Fiumicino, Milano-Malpensa and Venice-Marco Polo, medical triage tents have been set up landside to monitor arriving passengers exhibiting heat stress; airlines are required to notify ground handlers if onboard temperatures exceed 28 °C for more than 30 minutes before disembarkation. Carriers failing to report face fines up to €5,000 under Civil Aviation Authority (ENAC) Directive 4/2024. Trenitalia has reduced the maximum operating speed of selected Intercity services between noon and 18:00 to protect overhead line equipment, adding up to 25 minutes to journeys on the Milan–Naples axis. Freight operators using the Brenner and Tarvisio corridors must reroute during the hottest hours or present wagons certified for high-temperature braking systems. Employers with posted workers or business travellers should revisit duty-of-care protocols: provide bottled water vouchers, allow flexible scheduling and remind staff that local authorities may close outdoor construction sites when the perceived temperature (Humidex) exceeds 50 °C. Insurance providers have confirmed that emergency-room wait times in the Lazio and Emilia-Romagna regions doubled during the previous heat episode earlier in July. While airports remain fully operational, travellers should plan for possible slot delays caused by aircraft performance limits and tarmac-worker safety breaks. The Ministry will reassess the alert at 12:00 on 31 July.
