Too Darn Hot: How Summer Stages Are Threatened by Climate Change

ASHLAND, Ore. — Smoke from a raging wildfire in California prompted the Oregon Shakespeare Festival to cancel a recent performance of “The Tempest” at its open-air theater. Record flooding in St. Louis forced the cancellation of an outdoor performance of “Legally Blonde.” And after heat and smoke at an outdoor Pearl Jam concert in France damaged the throat of its lead singer, Eddie Vedder, the band canceled several shows.

Around the world, rising temperatures, raging wildfires and extreme weather are imperiling whole communities. This summer, climate change is also endangering a treasured pastime: outdoor performance.

Here in the Rogue Valley, the Oregon Shakespeare Festival is seeing an existential threat from ever-more-common wildfires. In 2018 it canceled 25 performances because of wildfire smoke. In 2020, while the theater was shut down by the pandemic, a massive fire destroyed 2,600 local homes, including those of several staffers. When the festival reopened last year with a one-woman show about the civil rights activist Fannie Lou Hamer, wildfire smoke forced it to cancel almost every performance in August.

“The problem is that in recent years there have been fires in British Columbia and in the mountains in Washington State and fires as far as Los Angeles,” said Nataki Garrett, the festival’s artistic director. “You have fire up and down the West Coast, and all of that is seeping into the valley.”

Even before this year’s fire season began, the festival moved the nightly start time of its outdoor performances later because of extreme heat.

Ashland is not the only outdoor theater canceling performances because of wildfires. Smoke or fire conditions have also prompted cancellations in recent years at the Butterfly Effect Theater of Colorado; the California Shakespeare Theater, known as Cal Shakes; the Lake Tahoe Shakespeare Festival in Nevada and the Getty Villa in Malibu, Calif., among others.

“We are one giant ecosystem, and what happens in one place affects everywhere,” said Robert K. Meya, the general director of the Santa Fe Opera, which stages open-air productions against a striking desert backdrop each summer, and which, in an era of massive wildfires near and far, has installed sensors to gauge whether it is safe to perform.

The reports of worsening conditions come from wide swaths of the country. “Last summer was the hardest summer I’ve experienced out here, because fires came early, and coupled with that were pretty severe heat indexes,” said Kevin Asselin, executive artistic director of Montana Shakespeare in the Parks, which stages free performances in rural communities in five Rocky Mountain West states, and has increasingly been forced indoors. “And the hailstorms this year have been out of control.”

In southern Ohio, a growing number of performances of an annual history play called “Tecumseh!” have been canceled because of heavy rain. In northwest Arkansas, rising heat is afflicting “The Great Passion Play,” an annual re-enactment of the crucifixion and resurrection of Jesus. In Texas, record heat forced the Austin Symphony Orchestra to cancel several outdoor chamber concerts. And in western Massachusetts, at Tanglewood, the bucolic summer home of the Boston Symphony Orchestra, more shade trees have been planted on the sweeping lawn to provide relief on hot days.

“Changing weather patterns with more frequent and severe storms have altered the Tanglewood landscape on a scale not previously experienced,” the orchestra said in a statement.

On Sunday, the U.S. Senate voted in favor of the nation’s first major climate law, which, if enacted into law, would seek to bring about major reductions in greenhouse pollution. Arts presenters, meanwhile, are grappling with how to preserve outdoor productions, both short-term and long-term, as the planet warms.

“We’re in a world that we have never been in as a species, and we’re going into a world that is completely foreign and new and will be challenging us in ways we can only dimly see right now,” said Kim Cobb, the director of the environment and society institute at Brown University.

Some venues are taking elaborate precautions. The American Players Theater in Spring Green, Wis., now requires performers to wear wicking undergarments when the heat and humidity rise, encourages actors to consume second act sports drinks, and asks costume designers to eliminate wigs, jackets and other heavy outerwear on hot days.

Many outdoor performing venues say that, even as they are bracing for the effects of climate change, they are also trying to limit the ways that they contribute to it. The Santa Fe Opera is investing in solar energy; the Hudson Valley Shakespeare Festival is planting native meadows; and the Oregon Shakespeare Festival is using electric vehicles.

The Oregon Shakespeare Festival, which before the pandemic had been one of the largest nonprofit theaters in the country, is, in many ways, patient zero. The theater is central to the local economy — the downtown features establishments with names like the Bard’s Inn and Salon Juliet. But the theater’s location, in the Rogue Valley of southern Oregon, has repeatedly been subject to high levels of wildfire smoke in recent years.

The theater, like many, has installed air quality monitors — there’s one in a niche in the wall that encircles the audience in the open-air Allen Elizabethan Theater, where this summer “The Tempest” is alternating with a new musical called “Revenge Song.” The device is visible only to the keenest of eyes: a small cylindrical white gadget with lasers that count particles in the passing breeze.

The theater also has a smoke team that holds a daily meeting during fire season, assessing whether to cancel or proceed. The theater’s director of production, Alys E. Holden, said that, ever since the time she opposed canceling a performance mid-show and later learned a technician had thrown up because of the air pollution, she has replaced her “show must go on” ethos with “If it’s too unsafe to play, you don’t play.”

This year the festival reduced the number of outdoor performances scheduled in August — generally, but not always, the smokiest month.

“Actors are breathing in huge amounts of air to project out for hours — it’s not a trivial event to breathe this stuff in, and their voices are blown the next day if we blow the call,” Holden said. “So we are canceling to preserve everyone’s health, and to preserve the next show.”

Wildfire-related air quality has become an issue for venues throughout the West. “It’s constantly on our mind, especially as fire season seems to start earlier and earlier,” said Ralph Flores, the senior program manager for theater and performance at the J. Paul Getty Museum, which has a 500-seat outdoor theater at the Getty Villa.

Air quality concerns sometimes surprise patrons on days when pollution is present, but can’t be readily smelled or seen.

“The idea that outdoor performance would be affected or disrupted by what’s happening with the Air Quality Index is still a fairly new and forward concept to a lot of people,” said Stephen Weitz, the producing artistic director at the Butterfly Effect Theater of Colorado, which stages free shows in parks and parking lots. Last summer the theater had to cancel a performance because of poor air quality caused by a faraway fire.

Another theater there, the Colorado Shakespeare Festival, is now working with scientists at the affiliated University of Colorado Boulder on monitoring and health protocols after a fire more than a thousand miles away in Oregon polluted the local air badly enough to force a show cancellation last summer. Tim Orr, the festival’s producing artistic director, recalled breaking the news to the audience.

“The looks on their faces were surprise, and shock, but a lot of people came up and said ‘Thank you for making the right choice,’” he said. “And when I stepped offstage, I thought, ‘Is this going to be a regular part of our future?’”

Planning for the future, for venues that present out of doors, now invariably means thinking about climate change.

Oskar Eustis, the artistic director of the Public Theater, which produces Free Shakespeare in the Park at the Delacorte Theater in New York’s Central Park, said that the 2021 summer season, when the theater reopened after the pandemic shutdown, was the rainiest in his two decades there. “I could imagine performing more in the fall and spring, and less in the summer,” he said.

In some places, theater leaders are already envisioning a future in which performances all move indoors.

“We’re not going to have outdoor theater in Boise forever — I don’t think there’s a chance of that,” said Charles Fee, who is the producing artistic director of three collaborating nonprofits: the Idaho Shakespeare Festival, the Lake Tahoe Shakespeare Festival and Great Lakes Theater in Cleveland. Fee has asked the Idaho board to plan for an indoor theater in Boise.

“Once it’s 110 degrees at 6 o’clock at night, and we have these occasionally already, people are sick,” he said. “You can’t do the big Shakespeare fight, you can’t do the dances in ‘Mamma Mia.’ And you can’t do that to an audience.”
