Red Heat Alerts Hit Rome, Florence and Three More Italian Cities
Italy’s Ministry of Health has issued Level 3 red heatwave alerts for five cities that together attract the majority of the country’s international visitors: Rome, Florence, Bologna, Brescia and Turin. The alerts cover late May 2026 and mark Italy’s first significant heat event of the year, arriving several weeks ahead of the usual July–August peak.
What Level 3 means for visitors
A red alert signals conditions that pose a health risk to the general population, not just vulnerable groups. The Ministry advises everyone to:
- Stay out of direct sunlight between 11:00 and 16:00
- Carry and drink water frequently
- Seek air-conditioned or shaded spaces during peak heat
- Avoid strenuous outdoor activity in the middle of the day
Daytime highs across the affected cities are reaching 32–36°C, with high humidity pushing the perceived temperature considerably higher.
Adjusting your itinerary
The simplest practical response is to shift sightseeing earlier in the day. Arriving at Rome’s Colosseum or the Vatican before 09:00, or at Florence’s Uffizi at opening time, means cooler air and smaller queues. Some venues adjust entry or hours during red alert periods — check individual websites before travelling.
Afternoons are well suited to indoor activities: air-conditioned museums, dim churches, galleries or a long lunch in a shaded courtyard. Evening sightseeing becomes comfortable again after 19:00 as temperatures ease.
What to expect in the weeks ahead
The current heat is part of a broader European pattern affecting Portugal, France and the UK simultaneously, and conditions are forecast to moderate in early June.
