Overview

• Temperatures are running 4–6°C above seasonal norms and are expected to hit 36–37°C across the Po Valley and surge to 38°C in Tuscany, Lazio, Sicily, and Sardinia.
• An African anticyclone is channeling Saharan air into Italy, sustaining the current heatwave and limiting any temporary relief from thunderstorms.
• A cool upper-level vortex over the southern Tyrrhenian has driven severe afternoon storms with hail and wind gusts over Sicily and inland Calabria.
• While much of northern Italy remains largely sunny, the Alpine regions of Piemonte, Lombardia, and Trentino-Alto Adige face sporadic convective showers during peak heat hours.
• Forecasters from 3bMeteo and ilMeteo.it predict the intensified heat and weather volatility will extend through next week, making it the hottest stretch of the season so far.
