The summer of 2026 has begun with one of the most extreme heatwaves recorded in recent years, marking a significant shift in weather patterns across northern Italy. According to data collected by 3bmeteo and analyzed by *Il Sole 24 Ore*, temperatures above 30 degrees Celsius have been sustained for more than ten hours each day in many cities during the period between June 15 and June 25. This phenomenon is particularly pronounced in major northern Italian cities such as Milan, Bologna, and Turin, where the duration of high temperatures has extended beyond previous records. The analysis confirms a long-term trend observed since 2008, indicating that heatwaves are not only becoming more frequent but also lasting longer, with higher temperatures persisting for extended periods throughout the day.
Historical data shows that in 2008, during hot days, temperatures exceeded 30 degrees Celsius for approximately six hours daily, which accounted for about one-quarter of the day. By 2025, this figure had risen significantly, with over nine hours of "hot" conditions recorded each day in nearly all major cities studied. The latest figures from June 2026 reinforce this upward trajectory, especially in the north, where the average number of hours exceeding 30 degrees has increased dramatically. For instance, in Milan, the exposure to extreme heat has reached almost 12 hours per day, a stark contrast to earlier decades.
Meteorological experts attribute this prolonged exposure to several factors. One primary cause is the positioning of the anticyclonic ridge over Western Europe, which channels warm air masses from the subtropical regions into Spain, France, and northern Italy. This atmospheric configuration results in persistent high-pressure systems that trap heat, leading to extended periods of elevated temperatures. Additionally, the reduced thermal variation in urban areas plays a crucial role. Urban heat islands contribute to maintaining higher nighttime temperatures, preventing the cooling effect typically seen in less densely populated regions or near coastal areas where sea breezes help moderate temperatures.
Milan exemplifies this pattern, experiencing some of the highest levels of heat exposure. The city's highly urbanized landscape, characterized by extensive use of asphalt and concrete, exacerbates the heat retention effects. These materials absorb and retain heat more effectively than natural surfaces, causing temperatures to remain high even after sunset. As noted by meteorologist Alessandro Conigliaro from 3bmeteo, the slow decrease in temperature post-sunset further prolongs the duration of heat exposure compared to other urban centers or peripheral areas.
This year’s heatwave follows two distinct phases. The first wave occurred towards the end of May, bringing temperatures 10–15 degrees above normal in parts of western France, England, and Wales. A more severe phase began on June 22, with night-time temperatures in France consistently remaining above threshold levels. This continuous warmth has contributed to the extended duration of heat in northern Italian cities, where the combination of geographical location and urban infrastructure amplifies the impact of high temperatures.
As the summer progresses, concerns grow regarding the health implications of prolonged heat exposure, particularly in densely populated urban environments. Public health officials and environmental scientists continue to monitor these trends closely, emphasizing the need for adaptive measures to mitigate the risks associated with increasingly frequent and intense heatwaves. The ongoing analysis of climate indices will provide further insights into how these patterns evolve and their potential long-term impacts on both human populations and ecosystems.

OpenIndependentCenterFactual 95Objective 884 days agoThe article discusses common misconceptions about heatwaves by referencing physicist Gabriella Greison’s explanation on the Corriere della Sera. It clarifies that while hot days have occurred historically, the issue lies in the increasing frequency, intensity, and duration of extreme weather events, which are linked to climate change. The piece highlights that comparing single hot days across decades is misleading, as climate involves complex interactions between atmosphere, oceans, ice, vegetation, and currents. Greison emphasizes that rising global temperatures alter the distribution of extreme events, making heatwaves more likely and severe. The article also notes that feedback mechanisms, such as reduced evaporation from warmer soil, further amplify warming effects.

Il Sole 24 OreParty-aligned🔒Center4 days agoThe article discusses an extended heatwave affecting northern Italy, particularly cities like Milan and Bologna, where temperatures have exceeded 30°C for up to 12 hours a day. This trend has been observed since at least 2008, according to climate data compiled by the Sole 24 Ore. The increased frequency and duration of heatwaves are attributed to the positioning of high-pressure systems over Western Europe, which intensify the heat in inland areas. Urban heat islands contribute to prolonged exposure to high temperatures, especially in cities with significant urbanization and limited proximity to the sea. Experts note that this pattern is part of a long-term climate trend.
