Violent hailstorm halts Milan concert; summer weather turns erratic across Alps and Apennines

An open-air concert by Puerto Rican artist Bad Bunny was abandoned in Milan on Saturday night as a violent hailstorm swept across the city, forcing evacuation of the sold-out venue and prompting organisers to promise full refunds, according to the Guardian. Videos posted on social media showed hail the size of marbles falling on the crowd and stage, turning the event impossible to continue.

The incident reflects a broader volatility in Italian summer weather. The Alps and Apennines—regions of steep terrain and rapid altitude change—have become increasingly prone to sudden, intense storms as atmospheric conditions shift. Hailstorms of this magnitude can cause significant damage to crops, infrastructure and outdoor gatherings, a risk that intensifies as European summers grow more erratic.
