ROME, ITALY / RankWire.AI / – In 2026, Italy experienced its hottest summer since 1950, with the seasonal average reaching 24.3 degrees Celsius. This figure beat the previous record of 23.6 degrees, set in 2003. Researchers analyzed the meteorological summer from June to August, using an extensive climate dataset. Their findings marked a new peak in Italy’s 76-year temperature record. The National Research Council’s Institute for Bioeconomy compiled the data from measurements taken two meters above ground.
August’s temperature was particularly notable, with an average of 25.6 degrees Celsius across Italy. This was 5.2 degrees above the August average from 1951-1980. It also exceeded the 1991-2020 norm by 3.5 degrees. The previous August record of 24.6 degrees, set in 2024, was broken. August 2017’s high of 24.0 degrees was also surpassed. The new reading makes August 2026 the hottest in Italy’s national temperature record, surpassing both benchmarks.
July also set a record in the dataset, marking Italy’s warmest July and August since 1950. The summer followed an exceptionally warm spring, which averaged 12.1 degrees Celsius nationwide. Spring 2024 tied that record with the same average. Every month from January to August 2026 was warmer than the same months in 2025. These measurements indicate that elevated temperatures persisted well beyond summer across much of Italy.
August heat elevates national temperature averages
During the first eight months of 2026, the heat spread over a large part of Italy. About 70% of the country recorded temperature anomalies over 1 degree Celsius. Roughly 40% experienced anomalies greater than 2 degrees. The northwestern plains and parts of the Apennines showed the most significant deviations from historical averages. These regions include key agricultural zones. The heat and drought also impacted farmland, while Rome, Florence, and Turin faced repeated high-temperature spells during summer.
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 dating back to 1950. Researchers compared current data with previous decades across Italy. The 2026 summer average was 0.7 degrees higher than the 2003 record. August alone finished 1.0 degree above the previous monthly record set only two years earlier.
Mediterranean also experiences record-breaking warmth
Warm conditions extended into the Mediterranean during summer. A separate climate analysis found that sea-surface temperatures averaged about 27 degrees Celsius in July 2026. This was the highest July average in the dataset dating back to 1993. The analysis also revealed that 79% of the Mediterranean Sea experienced at least one intense marine heatwave. Though these sea measurements come from a different dataset than Italy’s land figures, both records show unusually high temperatures across the region during the same summer.
Italy’s record coincided with widespread European heatwaves, where climate monitoring indicates rapid temperature rises in recent decades. Europe is identified as the fastest-warming continent on Earth. The summer of 2026 also saw droughts and wildfires in parts of Europe. Italy’s latest data adds to the record summer temperatures, following an already warm start to the year. The national average of 24.3 degrees remains the highest Italian summer reading since records began in 1950.
