Extreme heat a rising threat to 2026 World Cup venues
Extreme heat during the FIFA Club World Cup made for a troubling preview of what is to come.
In short:
Ten of the 16 North America 2026 World Cup venues are at very high risk of experiencing extreme heat stress according to a new report called Pitches in Peril.
According to the report, 14 of the 16 World Cup stadiums in the US, Canada and Mexico exceeded safe-play thresholds in 2025.
What's next?
The 96-page report urges the soccer industry to commit to net-zero by 2040 and publish credible decarbonisation plans.
The 2026 World Cup could be North America's last without urgent climate adaptation, according to a new study highlighting extreme weather threats.
The Pitches in Peril report found that 10 of the 16 venues are at very high risk of experiencing extreme heat stress conditions.
By 2050, nearly 90 per cent of North America's host stadiums will require adaptation to extreme heat, while one third will face water demand equalling or exceeding supply.
The report also highlighted risks to 2030 and 2034 World Cup venues and examined the impact of a warming climate on grassroots soccer pitches once used by 18 iconic players.
"As someone from Spain, I can't ignore the climate crisis," said Spain's World Cup-winner Juan Mata, referencing last year's devastating Valencia floods.
"Football has always brought people together, but now it's also a reminder of what we stand to lose."
Troubling Club World Cup
This year's Club World Cup in the US offered a troubling preview, with conditions described as impossible by players.
The tournament saw extreme heat and thunderstorms force world soccer's governing body FIFA to adapt protocols — adding cooling and water breaks, shaded benches and air fans.
According to the report, 14 of the 16 World Cup stadiums in the US, Canada and Mexico exceeded safe-play thresholds in 2025 for at least three major climate hazards — extreme heat, unplayable rainfall and flooding.
Thirteen already experience at least one day each summer exceeding FIFA's threshold for drinks breaks of 32 degrees Celsius Wet-Bulb Globe Temperature (WGBT) — an internationally recognised index used to measure human heat stress in direct sunlight.
Temperatures in Atlanta, Dallas, Houston, Kansas City, Miami and Monterrey exceeded that mark for two months or more.
Ten experience at least one day each summer with a WBGT of 35C — identified by climate scientists as the limit of human adaptability to extreme heat, with Dallas (31 days) and Houston (51) worst hit.

While Dallas and Houston stadiums will mitigate heat with roofs, climate risks extend beyond elite venues.
The report says forward Mo Salah's Egyptian home ground could face more than a month of unplayable heat annually, while Nigeria captain William Troost-Ekong's childhood pitch could see 338 days of extreme heat by 2050.
"As we move further into the decade, risks will continue growing unless we take drastic measures, such as moving competitions to winter months or cooler regions," Piers Forster, director of the Priestley Centre for Climate Futures in Leeds, said.
The 96-page report urges the soccer industry to commit to net-zero by 2040 and publish credible decarbonisation plans and calls on tournament organisers to create adaptation funds.
It also said 91 per cent of 3,600 fans polled across the three hosts want the 2026 World Cup to be a sustainability role model.
