Is Phoenix Now Too Hot for Outdoor Concerts in the Summer? 

On July 18, 1991, Phoenix, Arizona hosted the first Lollapalooza. By the time gates opened, those who were there estimate it was 110 degrees.  

Many artists on the bill — Butthole Surfers, Rollins Band, Ice T — felt beat up by the heat, but it was only Nine Inch Nails, whose sequencer malfunctioned after sitting in the sun, that ended their performance after two songs because of it. Frontman Trent Reznor made his feelings about the situation known as he flipped over amps and mic stands on his way offstage.  

“I would advise groups like that not to play outside in that type of heat,” says Danny Zelisko, who partnered with Perry Farrell to promote the festival that year. “Fortunately, there was a whole lineup of groups behind them that didn’t have to rely on electronics.” 

Thirty-three years later, Phoenix has grown into the nation’s fifth largest city, with 1.6 million residents. It’s also the country’s hottest major metropolitan area, with scientists attributing the city’s rising average temperatures to both carbon emissions and heat trapped by man-made structures as development sprawls further into the Sonoran Desert. Last year was the warmest on record globally, according to the National Weather Service, and the fourth hottest on record in Phoenix. 

Amid a heatwave last July, the city clocked 19 days with record-high temperatures, including two that reached 119. Last July 22, a show by rock act Disturbed at the city’s Talking Stick Resort Amphitheatre was postponed when the band’s equipment wouldn’t work in the 118-degree heat. A month later, 50 Cent postponed a show at the same venue due to an excessive heat warning.  

A major tour stop for acts moving through the Southwest, Phoenix is home to many small, mid-sized and large-scale venues. Outdoor spaces include the 20,000-capacity Talking Stick, which is operated by Live Nation, and the 5,000-capacity Mesa Amphitheatre in nearby Mesa, Ariz., both of which host shows over the summer. (This summer, Mesa’s schedule is down to one summer show, in August, from several last year. May and August 2023 sets by Interpol and My Morning Jacket were moved to nearby indoor venues. A representative for the Amphitheatre did not immediately respond to Billboard‘s request for comment about whether these moves were heat related.)

But amid extreme heat — which is again currently gripping the city, many other areas of the U.S. and the world beyond — is Phoenix simply getting too hot to play in the summer, or is it business as usual? 

Zelisko, who’s put on shows in the city for the last 50 years and has worked in nearly all its indoor and outdoor venues with his company Danny Zelisko Presents, says agents often ask about the realities of playing there in the summer. But despite concerns, “The fact is that economics come into it as well, and in many cases they can make more money outside, so sometimes acts just grin and bear it.” 

Given that many summer tours are routed through amphitheaters and thus designed specifically for these types of spaces, it can also be difficult to move into a different kind of venue for a single show.  

But certain artists “just won’t play outside when it’s this hot,” Zelisko adds. “It’s a wise move, because you’re really putting your crew out. These people will finish a show in Albuquerque, drive all night, show up here at 7 a.m. to load in, then do it all over again. Throwing a super-hot day into the mix is hard on some people.” 

Steven Chilton, who promotes mostly indoor club shows in Phoenix under the name Psyko Steve, agrees the city is “a little slower” in summer, with some artists routing further north. 

But Talking Stick Resort Amphitheatre’s head of venue operation Karl Adams says he’s seen “no major changes” in how shows have been routed through the venue in recent years. This summer, Talking Stick has hosted shows by artists including Kenny Chesney, Paula Abdul and Cage the Elephant, with Sammy Hagar, Megadeth and more on the calendar through the end of August.  

With some artists and fans willing to brave the Phoenix heat for a show, safety protocols at both outdoor and indoor venues are crucial. In the last 30 to 40 years, Zelisko says more responsibility has fallen on promoters to look out for crowds in the heat. “As it’s turned into a business where you put an act up any time of year that you can get them, promoters really plan for what’s going to happen on game day,” he says. “You have to look out for people, because you want them back as a customer.” This is particularly true for venues that have large expanses of concrete or asphalt, which can get to 130 degrees or hotter on a warm day. 

At Talking Stick, protocols include encouraging fans to bring their own water bottles and fill them at free water stations. The venue is equipped with misting fans and cooling stations, provides free sunscreen and even has onstage air conditioning for artists. It also emails ticket holders prior to the event with show information that includes advice on how to prepare for weather, with this info also posted to the venue’s social accounts. Zelisko recalls handing out cooling ice pack necklaces at particularly hot shows, creating shaded resting areas and putting up pools backstage for bands to jump in after a set.  

“When you’re a fan in line and somebody goes through handing out water, it’s a simple gesture, but very appreciated,” says Zelisko. “You’ve got to be thinking about that stuff, because you don’t want people dropping by the time they come in.”  

That was the worst-case scenario outcome last December in Rio de Janeiro, when a 23-year-old fan died from heat exhaustion in a hospital after passing out during the second song of a Taylor Swift concert. Fans lined up for hours before the show in temperatures that reached 105, and many accused organizers of not delivering enough water supplies for the more than 60,000-person crowd. Fans also reported that they were not allowed to take their own water into the stadium.  

Last summer, heat exhaustion was widespread at shows throughout the U.S., with Jason Aldean experiencing heat stroke while onstage in Hartford, Conn. last July. Zelisko predicts that all promoters will eventually have to deal with some type of weather issue, and that the heat in places with humidity is more challenging than the dry heat of the desert.  

Still, “most of our 911 calls are heat related,” Chilton says of the Rebel Lounge, the 300-cap venue he manages. “It’s a big issue every summer, and it’s always the shows [that skew younger] where kids arrive early and want to sit outside in the sun for 10 hours in 110-degree heat, because they want to be first in line. Then they come into the venue exhausted and dehydrated and pass out. That’s a constant struggle for us.”  

At Rebel Lounge, fans are thus only allowed to wait outside an hour before any given show. Once inside, Chilton says the venue has a competitive advantage, given that it has stronger air conditioning than many other local indoor venues, with these places losing out on summer bookings because they don’t get as cool inside.  

While he says the cost of running multiple air conditioners is “very significant,” it’s worth it for the comfort of fans and artists. He recalls seeing a show at a nearby venue with weaker A.C., “and the band was furious at the end of the night.” Chilton says no one in the crowd complained, as locals know the realities of summertime in Phoenix. 

The general vibe among those interviewed for this story is that the effects of climate change don’t yet feel hugely significant “because it’s always blazing hot in the summer,” says Zelisko, who once successfully fried an egg on a sidewalk during a 120-degree day. “I’m not saying it’s not getting hotter, because there’s a lot of proof that says it is, but what are you going do about it? We’ve still got to live.” 

For Chilton, the difference thus far is “not necessarily that it’s more miserable, it’s that it’s miserable longer,” with heatwaves lasting longer than they used to. Still, the biggest weather issue he’s experienced wasn’t heat-related, but a fluke rainstorm during the two-day Zona Music Festival he produced in December of 2022.  

“I did the research, and since 1900 in Phoenix it’s only ever rained three times on that day,” he says. “It was the most rain Phoenix had seen on a single day in like, a decade.” 

Promoters also emphasize that Phoenix’s desert climate offers its own advantages. Adams of Talking Stick says the venue has “a longer season than some outdoor venues” since it can start hosting shows in April and continue them through the fall.  

Zelisko wishes more groups would come to town in January, February and March — when outdoor shows are impossible in much of the country due to the cold — “because that’s the best time of year here.” 

But as things stand, it’s unlikely summer shows will stop anytime soon in America’s hottest big city. “Performing outside in Phoenix in July is crazy,” says Zelisko. “But money makes people do crazy things.”
