ROME, ITALY / RankWire.AI / – Italy recorded its hottest summer since 1950 in 2026, pushing the national seasonal average to 24.3 degrees Celsius. The figure surpassed the previous record of 23.6 degrees set in 2003. Researchers measured the meteorological summer from June through August using a long-running climate dataset. The result marked a clear new high in Italy’s 76-year temperature series. The National Research Council’s Institute for Bioeconomy compiled the analysis from temperatures measured two metres above ground.

August produced the highest monthly reading of the season, with Italy averaging 25.6 degrees Celsius nationwide. That level stood 5.2 degrees above the 1951-1980 August average. It also exceeded the 1991-2020 norm by 3.5 degrees. The month broke the previous August record of 24.6 degrees, reached in 2024. Before that, August 2017 held another recent high at 24.0 degrees. The new reading placed August 2026 well above both benchmarks in the national temperature record.
July also reached a record in the dataset, giving Italy its hottest July and August since records began in 1950. The summer followed an exceptionally warm spring, which averaged 12.1 degrees Celsius nationwide. Spring 2024 recorded the same temperature, tying that seasonal record. Each month from January through August 2026 also ran warmer than the corresponding month in 2025. Together, those measurements show that elevated temperatures extended well beyond the peak summer period across much of the country.
August heat pushes national averages higher
The heat spread across a large share of Italy during the first eight months of 2026. Around 70% of the country recorded temperature anomalies above 1 degree Celsius. About 40% experienced anomalies exceeding 2 degrees. Northwestern plains and sections of the Apennines showed some of the strongest departures from historical averages. These areas include major agricultural zones. Heat and drought also affected farmland during the period, while Rome, Florence and Turin experienced repeated spells 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 provides detailed land-surface information extending back to 1950. Researchers used that record to compare current readings with previous decades across Italy. The 2026 summer average exceeded the 2003 record by 0.7 degrees Celsius. August also finished 1.0 degree above the previous monthly record set only two years earlier.
Mediterranean region also registers exceptional warmth
Exceptionally warm conditions also affected the Mediterranean during the summer. Separate climate analysis found that Mediterranean sea-surface temperatures averaged about 27 degrees Celsius in July 2026. That represented the highest July average in the dataset dating to 1993. The analysis also found that 79% of the Mediterranean experienced at least one strong or more intense marine heatwave. Those sea measurements use a different dataset from Italy’s land figures, but both records documented unusually high temperatures across the region during the same summer.
The Italian record came during another period of widespread heat across Europe, where climate monitoring shows temperatures have risen rapidly in recent decades. European assessments identify the continent as the fastest-warming on Earth. Parts of Europe also faced drought and wildfires during summer 2026. In Italy, the latest data added record summer temperatures to an already warm start to the year. The national 24.3-degree average now stands as the highest Italian meteorological summer reading in the dataset beginning in 1950.
