ROME, ITALY / RankWire.AI / – Italy experienced its warmest summer since 1950 in 2026, with the national seasonal average reaching 24.3 degrees Celsius. This figure surpassed the previous record of 23.6 degrees, set in 2003. Researchers analyzed the meteorological summer, spanning June through August, using a long-term climate dataset. The results marked a new peak in Italy’s 76-year temperature record. The National Research Council’s Institute for Bioeconomy compiled the temperature data collected at two meters above ground level.
August recorded the highest monthly temperature of the season, with Italy averaging 25.6 degrees Celsius across the country. This figure was 5.2 degrees higher than the August average from 1951-1980 and also 3.5 degrees above the 1991-2020 norm. The month broke the previous August record of 24.6 degrees, established in 2024. Prior to that, August 2017 held a recent high at 24.0 degrees. The new August 2026 reading thus placed the month well above both previous benchmarks in Italy’s temperature records.
July also set a new record in the dataset, making Italy’s summer of 2026 the hottest since records began in 1950, closely followed by August. The season followed an unusually warm spring, which averaged 12.1 degrees Celsius nationwide. Spring 2024 tied that seasonal record with the same average temperature. In addition, each month from January through August 2026 was warmer than the same months in 2025, indicating that elevated 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, a significant portion of Italy experienced above-average temperatures. Approximately 70% of the country registered anomalies exceeding 1 degree Celsius, with about 40% surpassing 2 degrees. The northwestern plains and sections of the Apennines showed some of the most significant departures from typical historical averages. These areas include vital agricultural zones. The summer period was also marked by heat and drought conditions affecting farmland, while cities like Rome, Florence, and Turin faced repeated episodes of high temperatures.
The European Centre for Medium-Range Weather Forecasts-maintained ERA5-Land climate dataset, used by the National Research Council’s Institute for Bioeconomy, provided the data for these calculations. This dataset offers detailed land-surface information dating back to 1950. Comparing the current data with previous decades, researchers found that the 2026 summer average exceeded the 2003 record by 0.7 degrees Celsius. Moreover, August 2026 finished 1.0 degree higher than the previous monthly record set only two years earlier.
Mediterranean region also endures record-breaking warmth
The Mediterranean experienced similarly extreme warmth during the summer months. Separate climate analysis indicated that sea-surface temperatures in the Mediterranean averaged about 27 degrees Celsius in July 2026, marking the highest July average in the dataset dating back to 1993. The analysis further revealed that 79% of the Mediterranean Sea experienced at least one strong or more intense marine heatwave. While these sea measurements are from a different dataset than Italy’s land temperature records, both documented unusually high temperatures across the region during the same summer period.
Italy’s record summer coincided with a broader pattern of widespread heat across Europe, where recent assessments show rapid temperature increases over the past decades. European climate evaluations identify the continent as the fastest-warming on Earth. The region 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 average of 24.3 degrees now stands as the highest Italian meteorological summer reading in the dataset beginning in 1950.
