Lollapalooza 2026 faced major weather disruptions on Saturday as heavy rain and flooding affected the festival grounds in Chicago, forcing organizers to delay several performances and shorten the sets of multiple artists.
The weather problems impacted the third day of the four-day festival at Grant Park, with the opening of the grounds pushed back several hours as crews worked to address the conditions.
Wolf Alice and CORTIS Sets Cut Short
Among the artists affected were Wolf Alice and CORTIS.
Wolf Alice's scheduled performance was shortened, with the British band ultimately playing a reduced set after the festival's delayed start. CORTIS also saw its performance time reduced as organizers adjusted the day's schedule.
The changes were part of wider scheduling disruptions that affected several performers throughout the afternoon.
Heavy Rain Creates Difficult Conditions
The overnight rainfall left parts of the festival grounds heavily saturated, creating difficult conditions for both festivalgoers and staff.
Organizers said they were working to clean up affected areas before opening the grounds. The official Lollapalooza safety information also advises attendees to follow updates through the festival's official channels when weather conditions affect schedules or site access.
Lollapalooza Adjusts the Schedule
Because of the delayed start, several performances were moved, shortened, or otherwise affected.
The festival's official schedule remains the best place for fans to check the latest performance times, particularly when severe weather leads to last-minute changes.
Despite the disruption, Lollapalooza continued with performances throughout the day as organizers worked to manage the challenging conditions.
More Artists Could Be Affected by Weather
Weather remains an important factor for outdoor festivals, and Lollapalooza's organizers have procedures in place for severe conditions, including possible evacuations and schedule changes when necessary.
Fans attending the festival are encouraged to monitor official announcements and schedule updates before heading to performances.
Lollapalooza 2026 is scheduled to run through Sunday, August 2, with performances from major artists across its final day.
The Bottom Line
Heavy rain and flooding disrupted the third day of Lollapalooza 2026, leading to delays and shortened performances for artists including Wolf Alice and CORTIS.
The situation highlights the challenges of staging a large outdoor music festival during severe weather, while organizers continue working to keep performances and attendees safe.
