Italy is bracing for a severe heatwave as a mass of hot air from Africa is set to push temperatures up to 10 degrees Celsius above the seasonal average later this week, meteorologists warn. The extreme weather alert comes on the heels of a record-breaking June in Western Europe, which was the hottest ever recorded, according to the European climate service Copernicus (C3S). The new heat spike is expected to exacerbate an already dire climate situation, with consequences for public health, agriculture, and infrastructure across the region.
The current weather pattern shows a relatively dry start to the day across most of the Italian peninsula, but afternoon clouds are expected to bring scattered showers and thunderstorms, particularly over the western Alps and the central-southern Apennines. This instability will persist through the weekend, with a small disturbance increasing cloud cover and precipitation, first in the north and then in inland areas of central and southern Italy. Despite these brief respites, temperatures are already running 5 to 6 degrees above normal, setting the stage for the more intense heat to come.
The worst is forecast to arrive next week, when a subtropical air mass is expected to cause thermometers to spike dramatically. The latest updates from meteorological models are alarming, showing a sustained period of extreme heat that could last several days. This third heatwave of the summer is poised to push temperatures toward 45 degrees Celsius in some areas, particularly in the south and on the islands of Sicily and Sardinia, according to additional forecasts. The prolonged heat is likely to strain power grids, increase the risk of wildfires, and pose serious health risks, especially for the elderly and those with pre-existing conditions.
Scientific data underscores the gravity of the situation. June 2026 was the hottest June on record for Western Europe, with an average temperature of 20.74 degrees Celsius — a staggering 3.05 degrees above the thirty-year average. This surpassed even the previous record set in June 2025. Globally, June 2026 ranked as the second hottest June ever recorded, with temperatures 1.39 degrees above pre-industrial levels. The Copernicus report describes a month marked by exceptional heatwaves, devastating wildfires, extreme drought, and record-high sea surface temperatures.
The oceans are also feeling the heat. The global average sea surface temperature reached an absolute record of 20.86 degrees Celsius. In the western Mediterranean Sea and along the Atlantic coasts, marine heatwaves have been observed, intensified by the ongoing El Niño phenomenon in the Pacific. These warm waters contribute to the intensity of land-based heatwaves and disrupt marine ecosystems.
Extreme heat is accompanied by severe drought across much of Western Europe, including Italy. Rainfall has been scarce, leaving soils parched and water reserves depleted. This dry conditions have fueled massive wildfires in Spain, Portugal, and southern France, while river flows have dropped dramatically. In contrast, the United Kingdom, Ireland, and Greece have experienced violent localized floods, highlighting the erratic nature of the changing climate.
The climate crisis is also evident at the poles. Sea ice extent has declined by 5 percent in the Arctic and 8 percent in Antarctica, both marking near-record lows for the time of year. The Copernicus report delivers a clear message: extreme weather events are no longer isolated incidents but part of a continuous chain. The succession of heatwaves between May, June, and July demonstrates that the planet is accumulating too much energy, dramatically increasing risks for agriculture, infrastructure, and human life.
As Italy prepares for the incoming heat, authorities are urging residents to take precautions, including staying hydrated, avoiding outdoor activities during peak heat hours, and checking on vulnerable neighbors. The coming days will test the resilience of communities already weary from a summer of climatic extremes.
