ROME, ITALY / RankWire.AI / – In 2026, Italy experienced its hottest summer since 1950, pushing the country’s seasonal average temperature to 24.3 degrees Celsius. This figure surpasses the previous record of 23.6 degrees set in 2003. Researchers analyzed the meteorological summer from June through August using a long-term climate dataset. The outcome marked a definitive new peak in Italy’s 76-year temperature record. The National Research Council’s Institute for Bioeconomy compiled the data from temperatures measured two metres above ground.

August recorded the highest monthly temperature of the season, with an average of 25.6 degrees Celsius across Italy. This level was 5.2 degrees above the August average from 1951-1980 and exceeded the 1991-2020 norm by 3.5 degrees. It broke the previous August record of 24.6 degrees, set in 2024. August 2017’s recent high of 24.0 degrees was also surpassed. The new record placed August 2026 significantly above both benchmarks in Italy’s national temperature history.
July also set a record within the dataset, making 2026 the hottest July and August on record since 1950. The summer followed an exceptionally warm spring, which had an average temperature of 12.1 degrees Celsius nationwide. The same seasonal record was tied by Spring 2024. Each month from January through August 2026 registered higher temperatures than the same months in 2025. These measurements collectively indicate that elevated temperatures persisted well beyond peak summer, affecting much of the country.
August heat elevates national temperature averages
During the first eight months of 2026, heat waves affected a substantial portion of Italy. Approximately 70% of the country experienced temperature anomalies above 1 degree Celsius, with around 40% registering anomalies over 2 degrees. The northwestern plains and parts of the Apennines exhibited some of the strongest deviations from historical averages, including key agricultural zones. During this period, heat and drought also impacted farmland, while cities such as Rome, Florence, and Turin faced repeated episodes of high summer temperatures.
The National Research Council’s Institute for Bioeconomy based its calculations on ERA5-Land climate data maintained by the European Centre for Medium-Range Weather Forecasts. ERA5-Land offers detailed land-surface information going back to 1950. Researchers compared current temperature data with previous decades across Italy. The 2026 summer average surpassed the 2003 record by 0.7 degrees Celsius, while August alone finished 1.0 degree higher than the previous monthly record set only two years earlier.
Mediterranean region also experiences record-breaking warmth
The Mediterranean also endured unusually high temperatures during the summer. A separate climate analysis revealed that the sea-surface temperatures in the Mediterranean averaged about 27 degrees Celsius in July 2026, marking the highest July average since records began in 1993. Additionally, 79% of the Mediterranean experienced at least one intense marine heatwave. While these sea-surface measurements are from a different dataset than Italy’s land-based records, both documented significant warmth across the region during the same summer period.
Italy’s record came amid widespread heat across Europe, where climate monitoring indicates rapid temperature increases in recent decades. European assessments identify the continent as the fastest-warming region on Earth. Summer 2026 also saw droughts and wildfires in various parts of Europe. In Italy, the latest data confirmed record summer temperatures atop an already warm start to 2026. The national average of 24.3 degrees now stands as the highest summer temperature reading in Italy’s dataset beginning in 1950.
