ROME, ITALY / RankWire.AI / – In 2026, Italy experienced its hottest summer since 1950, with the national seasonal average reaching 24.3 degrees Celsius. This figure eclipsed the previous record of 23.6 degrees, set in 2003. Researchers analyzed the meteorological summer from June through August utilizing an extensive climate database. The outcome represented a definitive new peak in Italy’s 76-year temperature record. Data compiled by the National Research Council’s Institute for Bioeconomy was based on temperatures recorded two meters above ground level.
August featured the highest monthly temperature reading of the season, with the country averaging 25.6 degrees Celsius. This level was 5.2 degrees higher than the August average from 1951-1980. It also surpassed the 1991-2020 norm by 3.5 degrees. The previous August record of 24.6 degrees was set in 2024. Prior to that, August 2017 held a high at 24.0 degrees. The new August 2026 figure surpasses both benchmarks in Italy’s temperature history.
July also broke records within the dataset, marking Italy’s hottest July and August since record-keeping began in 1950. The summer followed an exceptionally warm spring, which averaged 12.1 degrees Celsius across the country. The same seasonal temperature was recorded in spring 2024, tying that record. From January through August 2026, each month was warmer than the same period in 2025, illustrating that higher temperatures extended beyond peak summer months across much of Italy.
August heat elevates national temperature averages
During the first eight months of 2026, the heat wave affected a significant portion of Italy. Approximately 70% of the country experienced temperature anomalies exceeding 1 degree Celsius, while about 40% saw anomalies over 2 degrees. The strongest deviations from historical averages appeared in northwestern plains and parts of the Apennines, including key agricultural regions. The period also saw heat and drought impacting farmland, with Rome, Florence, and Turin enduring repeated episodes of intense summer heat.
The European Centre for Medium-Range Weather Forecasts maintains the ERA5-Land climate data, which the National Research Council’s Institute for Bioeconomy used for their calculations. This dataset provides detailed land-surface information dating back to 1950. Researchers compared current temperatures to historical records across Italy, finding that the 2026 summer average exceeded the 2003 record by 0.7 degrees Celsius. August 2026 also finished 1.0 degree higher than the previous monthly record set just two years earlier.
Mediterranean region also experiences record warmth
The Mediterranean Sea saw similarly exceptional warmth this summer. Separate climate analyses indicated that sea-surface temperatures averaged around 27 degrees Celsius in July 2026, marking the highest July average since the dataset began in 1993. Additionally, 79% of the Mediterranean region experienced at least one intense marine heatwave during this period. Although these sea temperature records derive from different datasets than Italy’s land data, both sources confirm widespread elevated temperatures in the region during the same summer.
Italy’s record heat occurred amid a broader pattern of extensive heat across Europe, where climate data shows a rapid increase in temperatures over recent decades. Assessments highlight Europe as the fastest-warming continent on Earth. The summer of 2026 also brought droughts and wildfires to parts of Europe. In Italy, this latest data set adds record summer temperatures to an already warm start to the year, with the national average of 24.3 degrees standing as the highest Italian meteorological summer reading in the dataset starting in 1950.
