Overview
- The Istituto per la bioeconomia of the CNR reported on Monday, September 7, that Italy's meteorological summer (June–August) averaged 24.3°C at 2 meters, exceeding the 2003 summer mean of 23.6°C.
- August 2026 produced an exceptional national mean of 25.6°C, which CNR‑Ibe says is 5.2°C above the 1951–1980 August average and higher than previous monthly records from 2017 and 2024.
- ERA5 Land heat maps show consecutive record months including a record spring and the hottest July and August since 1950, demonstrating a persistent seasonal shift in monthly temperature ranks.
- Observational datasets from GSOD and Ogimet document repeated high‑percentile heatwaves that hit Rome, Florence and Turin with daily maximums above the 90th percentile for multi‑day spells, increasing urban heat stress.
- Field glaciological work on the Marmolada shows a 23‑metre retreat and a fall from 92 to 83 hectares in surface area this year, a concrete sign of cryosphere loss that, together with crop exposure in the north‑west plains and Apennines, raises risks to agriculture and water supplies.
