ROME, ITALY / RankWire.AI / – The summer of 2026 in Italy marked the highest average temperature recorded since 1950, reaching 24.3 degrees Celsius across the nation. According to the National Research Council’s Institute for Bioeconomy, this figure surpassed the previous summer record set in 2003, which averaged 23.6 degrees Celsius throughout Italy. The 2026 data, covering June through August, is based on temperatures measured at two meters above ground level. This result places summer 2026 at the top of Italy’s 76-year temperature record.
August was particularly notable for its extreme heat. The monthly average temperature for August reached 25.6 degrees Celsius, surpassing the 1951-1980 August average by 5.2 degrees. It also exceeded the August norm of 1991-2020 by 3.5 degrees. The National Research Council’s Institute for Bioeconomy reported that August 2026 broke earlier monthly records of 24.6 degrees in 2024 and 24.0 degrees in 2017. The climate dataset used for Italy’s temperature analysis is ECMWF’s ERA5-Land.
Both July and August of 2026 are now recognized as the hottest months on record within the dataset, according to the institute’s heat maps. The summer followed a record-breaking spring, when Italy’s national average temperature reached 12.1 degrees Celsius. This seasonal milestone was matched in spring 2024. From January to August, each month in 2026 registered higher temperatures than the same months in 2025, extending Italy’s period of elevated temperatures across much of the year.
August Sets New Temperature Extremes
During the first eight months of 2026, temperature anomalies spread extensively across Italy. Approximately 70% of the country experienced anomalies above 1 degree Celsius, while around 40% saw anomalies exceeding 2 degrees. The most intense anomalies appeared in the northwestern plains and along the Apennines, regions that include large agricultural zones. Elevated temperatures and drought conditions affected some farming areas during this period. Cities like Rome, Florence, and Turin also endured repeated heatwaves in June, July, and August.
The record summer temperatures are derived from ERA5-Land data provided by ECMWF. This climate dataset offers land-surface temperature records dating back to 1950. Researchers compared these records to evaluate temperature trends across Italy over the full period. Italy’s summer average of 24.3 degrees exceeded the 2003 benchmark by 0.7 degrees. The August temperature of 25.6 degrees also surpassed the 2024 monthly record by 1.0 degree. All measurements represent air temperature at two meters above the surface.
Extensive Evidence of Widespread Italian Heatwaves
The broader Mediterranean region also experienced extraordinary heat during summer 2026. A separate study associated with Italy’s National Research Council found that sea-surface temperatures in the Mediterranean averaged about 27 degrees Celsius in July, marking the highest July average since 1993. The analysis revealed that 79% of the Mediterranean Sea experienced at least one significant or more intense marine heatwave. These marine temperature increases are recorded separately from Italy’s land-based temperature series used to establish the national summer record.
The summer heatwave in Italy coincided with a continent-wide trend of extreme warmth across Europe. Climate assessments identify Europe as the fastest-warming continent in recent decades. The season was also marked by droughts and wildfires affecting various regions. Italy’s hot summer followed months of above-average temperatures and included the hottest July and August within the ERA5-Land dataset, which has been tracking data since 1950. The figures confirm that summer 2026 stands as Italy’s most intense meteorological summer recorded in the series.
