Lollapalooza delayed three hours and early sets cancelled after Grant Park flooding on 1 August 2026

Heavy overnight rain flooded Chicago's Grant Park, submerging Hutchinson Field — home to Lollapalooza's T-Mobile and Allianz stages. Organisers pushed gates from noon to 3 p.m. CT on Saturday, 1 August 2026, cancelling most early performances. CORTIS's set was cut to 40 minutes and Wolf Alice's to roughly 30, per Variety. Sunday's closing lineup remains unchanged.
