ROME, ITALY / RankWire.AI / – In 2026, Italy experienced its most scorching summer since 1950, with a nationwide average temperature of 24.3 degrees Celsius. The National Research Council’s Institute for Bioeconomy noted that this figure surpassed the previous record set in 2003, which averaged 23.6 degrees Celsius across Italy. The calculation for 2026 covers June through August, based on temperatures measured two metres above ground, marking this summer as the hottest in Italy’s 76-year temperature record.
August was particularly intense, with an average temperature of 25.6 degrees Celsius, exceeding the 1951-1980 August average by 5.2 degrees and surpassing the 1991-2020 August norm by 3.5 degrees. The National Research Council’s Institute for Bioeconomy confirmed that August 2026 broke previous monthly records of 24.6 degrees in 2024 and 24.0 degrees in 2017. ECMWF maintains ERA5-Land, the climate dataset used for the Italian temperature assessment.
Both July and August 2026 ranked as the warmest months on record according to the institute’s heat maps, following a record-breaking spring when Italy’s average temperature hit 12.1 degrees Celsius. Spring 2024 also recorded that same temperature, tying the seasonal record. From January through August, each month in 2026 was warmer than its counterpart in 2025, extending Italy’s elevated temperatures across a significant part of the year.
August Shatters Previous Temperature Records
Temperature anomalies affected much of Italy during the first eight months of 2026. Around 70% of the country experienced anomalies exceeding 1 degree Celsius, while about 40% saw increases over 2 degrees. The most notable anomalies appeared in northwestern plains and along the Apennines, regions that include large areas of farmland. During this period, higher temperatures and drought conditions impacted agriculture, and cities such as Rome, Florence, and Turin faced repeated heatwaves in June, July, and August.
These records are based on ERA5-Land data from the ECMWF, which offers land-surface climate information dating back to 1950. Researchers compared temperatures across Italy over this period, finding Italy’s summer average of 24.3 degrees was 0.7 degrees higher than the 2003 benchmark. August’s 25.6-degree figure also surpassed the 2024 monthly record by 1.0 degree. These measurements refer to air temperature at two metres above ground surface.
Extensive Heat Across Italy and the Mediterranean
The broader Mediterranean region also faced exceptional heat during summer 2026. An analysis linked to Italy’s National Research Council revealed that sea-surface temperatures in the Mediterranean averaged around 27 degrees Celsius in July, the highest July average since 1993. Additionally, 79% of the Mediterranean experienced at least one intense marine heatwave. These marine data are distinct from land temperature records used to establish Italy’s national summer peak.
Italy’s record heat occurred amidst widespread summer warming across Europe. Climate assessments identify the continent as the fastest-warming region in recent decades. The season was marked by droughts and wildfires, with Italy experiencing months of above-average temperatures. July and August set new temperature records, establishing 2026 as Italy’s hottest summer in the ERA5-Land dataset series starting in 1950.
