ROME, ITALY / RankWire.AI / – In 2026, Italy experienced its warmest summer since 1950, with the seasonal average reaching 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 comprehensive climate dataset that has been collected over many years. The results marked a 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 level.
August recorded the highest monthly temperature of the season, with Italy averaging 25.6 degrees Celsius nationwide. This level was 5.2 degrees above the August average from 1951-1980. It also exceeded the 1991-2020 normal by 3.5 degrees. The previous August record of 24.6 degrees, set in 2024, was broken. August 2017 had previously recorded a high at 24.0 degrees. The new figure places August 2026 well above both these benchmarks in Italy’s temperature history.
July also set a new record in the dataset, making 2026 the hottest July and August since records began in 1950. The summer was preceded by an exceptionally warm spring, which averaged 12.1 degrees Celsius across the country. Spring 2024 matched that seasonal temperature, tying the record. Each month from January through August 2026 was warmer than the same months in 2025. These figures demonstrate that higher temperatures persisted well beyond the 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 above 1 degree Celsius, while about 40% saw anomalies surpassing 2 degrees. The northwestern plains and parts of the Apennines showed some of the strongest deviations from historical norms, including major agricultural regions. Throughout this period, heatwaves and drought conditions impacted farmland, with cities like Rome, Florence, and Turin enduring repeated episodes of intense summer heat.
The calculations by the European Centre for Medium-Range Weather Forecasts relied on ERA5-Land climate data maintained by the European Centre for Medium-Range Weather Forecasts. This dataset provides detailed land-surface data stretching back to 1950. The researchers used this record to compare current temperature readings with those from previous decades across Italy. In 2026, the summer average exceeded the 2003 record by 0.7 degrees Celsius, and August alone was 1.0 degree above the previous monthly record set only two years prior.
Mediterranean Sea region also experiences record warmth
The Mediterranean Sea region also saw extraordinary warmth during the summer months. Climate analysis revealed that sea-surface temperatures in the Mediterranean averaged around 27 degrees Celsius in July 2026, marking the highest July average since 1993. Additionally, 79% of the Mediterranean experienced at least one significant marine heatwave, some more intense than others. Although these sea temperature records are based on a different dataset than Italy’s land measurements, both records indicate unusually high temperatures across the region during the same summer period.
Italy’s record-breaking temperatures occurred amidst widespread heat across Europe, where climate monitoring highlights a rapid increase in temperatures in recent decades. European assessments identify the continent as the fastest-warming region on Earth. Summer 2026 also brought droughts and wildfires to parts of Europe. In Italy, the latest data added 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 since 1950 in the dataset.
