An intense Atlantic storm system has officially broken an exceptionally hot and humid summer across Italy, clearing the runway for the Azores High. Lorenzo Tedici, meteorologist for iLMeteo.it, confirmed that the oceanic high-pressure system will soon restore a pleasant and temperate climate nationwide. Yet, lingering atmospheric instability continues to grip parts of the Center-South and Northeast.
The End of a Thermal Anomaly on Friday
Friday marks the definitive conclusion of a prolonged thermal anomaly across the Italian peninsula. Unstable weather conditions initially strike the lower Lazio and Campania regions before shifting gradually toward the middle and lower Adriatic slopes, bringing a noticeable drop in temperatures.
Meanwhile, residual showers linger across the Veneto, Venezia Giulia, and Romagna areas. The rest of Northern Italy and the central Tyrrhenian regions are experiencing a progressive weather improvement.
Azores High Takes Charge on Saturday
On Saturday, September 12, the Azores High extends across the Center-North, securing predominantly clear skies. Maximum temperatures are forecast to stay comfortably below 27°C to 29°C, accompanied by a sharp decrease in humidity.
Conversely, southern regions including Puglia, Basilicata, Calabria, and Sicilia maintain variable conditions featuring isolated showers and a continued cooling trend.
Temperatures Fall Below 30°C Nationwide by Sunday
Ample sunny spells reach the extreme southern regions by Sunday, September 13. For the first time since May 24—the start of a subtropical heatwave that drove Summer 2026 to record-high seasonal averages—maximum temperatures across the entire country remain under 30°C.
Weather models indicate that stable and mild conditions will persist through the first part of the upcoming week before a potential new low-pressure system approaches northern Italy by Wednesday.
