ROME, ITALY / RankWire.AI / – The National Research Council’s Institute for Bioeconomy reports that Italy experienced its warmest summer since 1950 in 2026, with the national seasonal average reaching 24.3 degrees Celsius. This figure surpasses the previous record of 23.6 degrees, established in 2003. The researchers analyzed the meteorological summer months of June through August utilizing an extensive climate dataset. This outcome set a new peak in Italy’s 76-year temperature series, based on measurements taken two metres above ground level.
August emerged as the hottest month of the season, with an average temperature of 25.6 degrees Celsius across the country. This reading was 5.2 degrees higher than the August average for 1951-1980 and 3.5 degrees above the 1991-2020 norm. The previous August record of 24.6 degrees, recorded in 2024, was broken by this new figure. August 2017 previously held the recent high at 24.0 degrees. Overall, the 2026 August temperature significantly exceeded both benchmarks in Italy’s national temperature record.
July also set a new record in the dataset, making 2026 the hottest July and August since 1950. The summer was preceded by an exceptionally warm spring, which had an average temperature of 12.1 degrees Celsius across Italy. That same seasonal record was matched in spring 2024. Additionally, each month from January through August 2026 registered higher temperatures than the same months in 2025, indicating that elevated heat persisted well beyond summer across much of the country.
August’s heat elevates national temperature averages
Throughout the first eight months of 2026, the heatwave affected a significant portion of Italy. Approximately 70% of the nation experienced temperature anomalies exceeding 1 degree Celsius, while around 40% saw anomalies surpassing 2 degrees. The northwestern plains and parts of the Apennines exhibited some of the most pronounced deviations from historical averages, impacting key agricultural zones. During this period, heatwaves and drought conditions also impacted farmland, with Rome, Florence, and Turin enduring repeated episodes of high summer temperatures.
The National Research Council’s Institute for Bioeconomy calculated these figures based on ERA5-Land climate data maintained by the European Centre for Medium-Range Weather Forecasts. ERA5-Land offers detailed land-surface climate information dating back to 1950. Researchers compared current temperature readings with data from previous decades across Italy. In 2026, the summer average exceeded the 2003 record by 0.7 degrees Celsius, and August alone finished 1.0 degree above the previous monthly record set just two years prior.
Mediterranean Sea also records unprecedented warmth
Warm conditions extended across the Mediterranean throughout the summer. Separate climate analyses reveal that the sea-surface temperatures averaged around 27 degrees Celsius in July 2026, marking the highest July average in the dataset dating back to 1993. The same studies found that 79% of the Mediterranean experienced at least one intense marine heatwave during this period. While these sea measurements are derived from a different dataset than Italy’s land-based figures, both documented remarkably high temperatures during the summer of 2026.
Italy’s record summer coincided with a broader heatwave affecting much of Europe, where climate monitoring indicates rapid temperature increases over recent decades. European assessments describe the continent as the fastest-warming region on Earth. During summer 2026, parts of Europe also faced droughts and wildfires. In Italy, the latest data added record summer temperatures to an already warm start to the year, with the 24.3-degree average establishing the highest Italian meteorological summer reading recorded since 1950.
