Italy is placing nearly all of its major cities on the country's highest heat alert as an intense heatwave continues to grip the nation. Nineteen large urban centres, including Rome, Milan and Naples, are already under a red warning, and the alert is set to extend to almost every major city by Monday.
The red alert is the most severe level in Italy's heat warning system and reflects weather conditions that pose a significant risk to health. Vulnerable groups, including older people, young children and individuals with chronic medical conditions, are considered to be at the greatest danger during such episodes, as prolonged exposure to extreme heat can quickly take a toll on the body. The warnings are particularly significant in densely populated urban areas, where temperatures are often amplified by buildings and paved surfaces.
The extreme temperatures are being driven by a surge of hot air from Africa, which has pushed the mercury towards 40 degrees Celsius in several areas. Forecasters say the heat is also bringing so-called tropical nights, when overnight temperatures fail to drop below 20 degrees Celsius, leaving residents with little relief and making it harder for homes and buildings to cool down before the next day's heat arrives.
The heatwave is hitting Italy at the height of the summer season, when the country's main tourist destinations are at their busiest. Visitors and residents alike are facing sweltering daytime conditions, and in cities such as Rome and Naples, where many popular attractions are outdoors, tourists must contend with prolonged exposure to the sun while moving between historic sites. Milan, the country's financial and industrial capital, is also under the red alert, underlining that the heat is affecting economic hubs as well as holiday destinations.
The list of affected cities spans the length of the country, showing that the heatwave is not limited to any single region. Milan in the north, Rome in the centre and Naples in the south are all affected, along with many other urban centres in between.
In practical terms, a red alert is intended to encourage people to avoid strenuous activity and direct sun exposure during the hottest hours of the day, typically between late morning and mid-afternoon. It also serves as a reminder to check on elderly neighbours and relatives, who are often the most affected by sustained high temperatures.
Italy's heat alert system is designed to inform the public about weather conditions that could have serious consequences for health and daily life. Red is the highest of several warning levels, and its activation across so many cities at once underscores the unusual intensity and geographical reach of this heatwave.
The situation has drawn renewed attention to the dangers of extreme summer heat, which has become a recurring concern across southern Europe. Local services are monitoring the situation closely as temperatures show little sign of easing in the short term, and further updates to the alert level are expected over the weekend.
By Monday, all but two of Italy's major cities are expected to be under the red alert, reflecting the scale of the challenge facing the country. The coming days will show how effectively urban centres can protect their populations during one of the most widespread heat episodes of the summer.
