Italy Issues Red Heat Alerts as Temperatures Near 40°C
The Italian Ministry of Health re‑activated its heat‑wave alert on 28 July 2026, issuing a level‑3 (red) warning for Campobasso and raising the alert levels for many other cities across the peninsula. The colour‑coded map shows green alerts shrinking to just three cities while yellow and orange warnings spread to dozens of locations, including Milan, Rome, Naples and Palermo.
Meteorologists forecast that an African anticyclone will dominate the Mediterranean through early August, driving temperatures up to 38‑41 °C in the Po Valley, central Italy and parts of the south. Night‑time temperatures are expected to remain above 25 °C, creating so‑called “tropical nights”. The fourth heat wave is projected to last until the first week of August, with peak conditions persisting into the weekend of 7‑8 August. Health officials warn that the extreme heat poses serious risks to the elderly, children and people with chronic illnesses and advise precautionary measures such as ample hydration, avoiding strenuous outdoor activity during midday and keeping indoor temperatures moderate.
