ROME, ITALY / RankWire.AI / – In 2026, Italy experienced its most scorching summer since 1950, with an average temperature across the nation reaching 24.3 degrees Celsius. According to the National Research Council’s Institute for Bioeconomy, this figure surpasses the previous summer record set in 2003, which had an average of 23.6 degrees Celsius. The data for 2026, covering June through August, is based on temperature measurements taken at two metres above ground level, making this summer the warmest in Italy’s 76-year temperature record series.
August stood out as the most intensely hot month, with a nationwide average temperature reaching 25.6 degrees Celsius, which is 5.2 degrees higher than the August average from 1951-1980. It also exceeded the August norm for 1991-2020 by 3.5 degrees. The National Research Council’s Institute for Bioeconomy noted that August 2026 eclipsed previous monthly records of 24.6 degrees in 2024 and 24.0 degrees in 2017. The climate dataset used for this analysis is ECMWF’s ERA5-Land.
Both July and August 2026 have been identified as the hottest months on record within the dataset, as shown by the institute’s heat maps. This follows a record-breaking spring where Italy’s national average temperature hit 12.1 degrees Celsius, matching the seasonal record set in 2024. From January through August, each month in 2026 was warmer than the same month in 2025, extending the pattern of elevated temperatures across most of the calendar year.
August Sets New Temperature Highs
Temperature anomalies were widespread throughout Italy during the first eight months of 2026, with roughly 70% of the country’s territory experiencing anomalies exceeding 1 degree Celsius, and about 40% seeing anomalies over 2 degrees. The most significant anomalies were concentrated in northwestern plains and along the Apennines, regions that include large agricultural areas. These zones faced increased heat and drought conditions that impacted farming, while cities such as Rome, Florence, and Turin endured multiple heatwaves in June, July, and August.
The record temperatures derive from ERA5-Land data provided by ECMWF, a climate dataset extending back to 1950. The researchers utilized this data to compare Italy’s temperature trends over the entire period. Italy’s summer average of 24.3 degrees stood 0.7 degrees above the 2003 benchmark, while August’s 25.6-degree figure surpassed the 2024 monthly record by 1.0 degree. These measurements correspond to air temperature at two metres above the ground surface.
Extensive Heatwaves and Rising Temperatures Mark Summer 2026
The broader Mediterranean region also experienced extraordinary heat during summer 2026, with a separate analysis linked to Italy’s National Research Council revealing that sea-surface temperatures in the Mediterranean averaged approximately 27 degrees Celsius in July, marking the highest July average since 1993. The same study found that 79% of the Mediterranean Sea experienced at least one strong or more intense marine heatwave, though these marine temperature anomalies are separate from the land-based temperature records used to define Italy’s summer heat record.
Italy’s record-breaking summer unfolded amid widespread heat across Europe, a continent identified by climate assessments as the fastest-warming region globally in recent decades. The season was also marked by droughts and wildfires that impacted parts of Europe, with Italy enduring months of above-average temperatures, including the hottest July and August in the historical temperature series. Overall, the figures confirm that summer 2026 is the hottest meteorological summer recorded in Italy since the ERA5-Land dataset began in 1950.
