Italy's Ministry of Health has issued a red alert for all 27 major cities, including popular tourist destinations such as Milan, Naples, Venice, and Rome, for Thursday, 6 August 2026. Temperatures across the country are reaching levels considered a threat to health and wellbeing.
To help visitors manage the heat, the ministries of tourism and culture are allowing some attractions to remain open into the evening. The Colosseum in Rome will be open on Fridays and Saturdays from 19:45 to 23:30, while the Pantheon in Rome will be open daily, except Thursdays, from 19:00 to 23:00. Sforza Castle in Milan will be open from 17:30 until 19:30.
Simone Quilici, director of the Archaeological Park of the Colosseum, advises against visiting outdoor attractions during Italy's hottest hours, which are typically after lunchtime. Cooling fans with mists have been installed at the Colosseum entrances, and medical stations have been increased for emergencies.
Experts suggest seeking out air-conditioned museums, churches, cooking classes, and wine tasting sessions as alternatives to walking tours. Mateo Medina, director of operations at Vivicos International Travel, has observed higher demand for early morning tours starting at 08:00 and has introduced tours from 22:00 until midnight in Rome.
For those driving, Dr Agata Chrzanowksa, an art historian and tour guide in Florence, recommends the hills and mountains north of the city, particularly the Garfagnana region, as a good escape from the heat. Booking tickets in advance for popular landmarks like the Vatican is also advised to avoid queuing in high temperatures.
