Summerfest drew 568,711 attendees to Henry Maier Festival Park across the festival’s three weekends. That’s a drop of 5.6% compared with the 602,231 fans who passed through the gates for the nine-day run in 2025.
But adding the 44,764 fans who attended two sold-out Garth Brooks performances on the two days immediately prior to the Summerfest’s formal kick-off on June 18, this year’s attendance figure jumps to 613,475 fans, which would mark a nearly 2% increase over last year’s attendance, according to figures released by Milwaukee World Festival Inc.
Festival organizers also announced that Summerfest 2027 will take place June 24-26, July 1-3 and July 8-10, a week later than this year’s festival.

Although weather didn’t force any major cancellations this year, the festival – which hired more than 2,100 seasonal workers – dealt with a severe heat wave on the final weekend, with high temperatures in the upper 90s, excessive heat warnings and occasional scattered rain.
“Summerfest is proud to be an independent music festival that celebrated the very best of live music, unforgettable fan experiences and meaningful community impact,” Milwaukee World Festival CEO Sarah Pancheri said in a statement. “Seeing hundreds of thousands of fans come together and make lasting memories is what Summerfest is all about.”
Summerfest’s attendance remains below pre-pandemic levels. In 2019 – the year before the COVID-19 pandemic and the resulting cancelation of Summerfest in 2020 – more than 718,000 people attended the festival. Nearly 832,000 people flocked to Summerfest in 2017, the high-water mark since 2015.
Throughout the run of Summerfest 2026, the festival hosted three additional sold-out shows from Ed Sheeran, Post Malone and Megan Moroney. In all, 600 performers took to the stages at Henry Maier Festival Park along Milwaukee’s lakefront, including 176 making their festival debut.
More than 13% of attendees gained access through one of Summerfest’s 15 free or discounted admission promotions, according to Milwaukee World Festival. Those promotions benefited local organizations through donations, including 38,400 meals donated to Feeding America Eastern Wisconsin, Northcott Neighborhood House and Hunger Task Force; 18,257 diapers collected for United Way of Greater Milwaukee & Waukesha County’s Diaper Bank Network; and 4,241 children’s books for Next Door to support early childhood literacy.
