The heat itself may become dangerous for everyone present.
As the 2026 FIFA World Cup prepares to unfold across sixteen North American cities in the height of summer, organizers are reckoning with a force no stadium upgrade can contain: the rising heat of a warming planet. Fourteen of sixteen venues face conditions where temperatures and humidity could push human bodies toward their limits — threatening not just athletes at full exertion, but the tens of thousands of fans, workers, and officials who gather around them. The measures being assembled — hydration breaks, cooling stations, adjusted kickoff times, multilingual alerts — represent humanity's current best answer to a question that will only grow more urgent with each passing tournament.
- Wet-bulb temperatures in cities like Dallas, Houston, and Monterrey could exceed 90°F during afternoon matches, creating genuine risk of heat stroke and death for players, fans, and workers alike.
- The warning signs are already written in recent history — Qatar's World Cup was moved to winter precisely because of heat, and last year's Club World Cup drew urgent warnings from the global players' union about conditions at future tournaments.
- FIFA and host cities are deploying a layered defense: mandatory mid-half hydration breaks, enclosed stadiums for the hottest time slots, medical teams with ice immersion equipment, and emergency heat response plans ready to activate.
- Cities are reaching beyond the stadiums — Seattle is exploring air-conditioned buses at fan festivals, Los Angeles will broadcast real-time heat emergency data, and New York City will push heat safety alerts in fourteen languages to 1.5 million people.
- Researchers caution that passive information campaigns rarely change behavior at the scale of a World Cup, and climate experts warn that without structural redesign, future summer tournaments will only grow more dangerous.
The 2026 World Cup arrives in the United States, Mexico, and Canada during June and July — the hottest months of the year across much of the continent. Researchers have found that fourteen of the sixteen host stadiums will face extreme heat conditions, with wet-bulb temperatures in cities like Dallas, Houston, and Monterrey potentially exceeding 90 degrees Fahrenheit in the afternoons. These are not merely uncomfortable numbers. For players running at full intensity, fans sitting in open sun for hours, and workers managing crowds on their feet, the risks include dehydration, heat stroke, and death.
The problem carries recent precedent. The 2022 World Cup in Qatar was relocated to winter specifically because of heat concerns. After last year's Club World Cup saw temperatures soar past 90 degrees across many venues, the global players' union issued a formal warning that extreme heat would pose an even greater threat at the next two men's tournaments — including the 2030 edition co-hosted by Spain, Portugal, and Morocco.
FIFA and host cities have assembled a layered response. Players will receive mandatory three-minute hydration breaks at the midpoint of each half, and outdoor matches during peak heat hours have been strategically limited, with the warmest time slots assigned to four fully enclosed stadiums. Teams will have a minimum of three days' rest between matches and the standard five substitutions available.
Beyond the field, cities are building out public infrastructure. Vancouver will add misting stations if a heat warning is issued. Dallas will station medical personnel with ice immersion equipment at outdoor venues. Seattle is exploring air-conditioned buses at fan festivals. Los Angeles County will publish real-time heat emergency room data, while New York City will push heat safety alerts in fourteen languages to 1.5 million subscribers.
Yet researchers note the limits of these efforts. Passive information campaigns, however thorough, do not reliably change behavior at events of this scale. FIFA's dedicated Heat Illness Mitigation and Management Working Group is finalizing alert systems and standardized medical protocols, but climate advocates argue the deeper lesson is structural: the next time a World Cup comes to this part of the world, the tournament itself will need to be redesigned for a hotter planet.
The 2026 World Cup will unfold across sixteen cities in the United States, Mexico, and Canada during June and July—the hottest months of the year in much of North America. As global temperatures continue their upward climb, organizers are confronting a problem that cannot be solved with better marketing or stadium upgrades: the heat itself may become dangerous for everyone present.
According to research cited by Donal Mullan, a professor at Queen's University Belfast who has studied heat risks at this year's host venues, fourteen of the sixteen stadiums will experience extreme heat conditions. In cities like Dallas, Houston, and Monterrey, wet-bulb temperatures—a measure that accounts for humidity, wind speed, solar angle, and other factors—could exceed 90 degrees Fahrenheit in the afternoons. These are not merely uncomfortable conditions. Heat exposure, especially during physical exertion, can trigger nausea, dehydration, headaches, heat stroke, and in the worst cases, death. Players will be running at full intensity. Fans will be sitting in the sun for hours. Workers will be on their feet managing crowds. The risk is real and distributed across thousands of people.
The urgency of the problem became sharper in March, when record temperatures swept across large portions of the United States. It also echoes recent history. The 2022 World Cup in Qatar was moved from summer to winter specifically because of extreme heat concerns. Last year's Club World Cup took place in conditions where temperatures soared past 90 degrees in many areas, and afterward, the global players' union warned that extreme heat would likely pose an even greater threat at the next two men's World Cups. The 2030 tournament, co-hosted by Spain, Portugal, and Morocco, will face similar challenges.
FIFA and the host cities are not waiting passively. They have assembled a comprehensive response. Players will receive mandatory three-minute hydration breaks at the midpoint of each half, regardless of weather. Teams will be allowed the standard five substitutions, with a minimum of three days of rest between matches. Outdoor matches during the hottest hours of the day have been strategically limited, and kickoff times have been adjusted in certain markets. When possible, matches scheduled for the warmest time slots have been assigned to covered stadiums. Four stadiums are fully enclosed—BC Place in Vancouver, the Dallas facility, and two others—protecting players and spectators from direct exposure.
Beyond the field, cities are preparing infrastructure. Vancouver will add temporary water fountains, hand-washing stations, and misting stations if a heat warning is issued. Dallas will deploy medical personnel with ice and immersion bags at outdoor festivals and match venues. Seattle is exploring air-conditioned buses, tents, and water misters at fan festivals. Los Angeles County will broadcast real-time data on heat-related emergency room visits. New York City will send heat safety alerts in fourteen languages to 1.5 million subscribers and international visitors through multiple apps and messaging platforms.
Yet researchers acknowledge the limits of these measures. William Adams, an associate professor of kinesiology at Michigan State University who studies heat stress in athletes, notes that passive information campaigns—however well-intentioned—do not always change behavior. A more active approach would be needed, but that is not truly feasible at events of this scale.
FIFA has created a dedicated Heat Illness Mitigation and Management Working Group composed of medical and operational experts. They are finalizing heat-risk alert systems, coordinating medical action plans at stadiums, and establishing standardized guidelines. Medical teams will be stationed at FIFA Fan Festivals and around multiple stadiums. If conditions become dangerous enough, authorities will activate emergency heat response plans that include public safety messaging on how to recognize heat exhaustion and heat stroke.
Elliot Arthur-Worsop, founding director of For Football for Future, a group focused on environmental sustainability in soccer, frames the responsibility plainly: organizers have a social contract with fans and the sport's governing bodies to keep people safe. His organization published a climate report before this year's matches concluding that heat and other climate risks will intensify at most stadiums hosting matches in 2050. The next time the World Cup is awarded to this part of the world, he argues, the tournament will need to be structured differently and adapted to a hotter reality.

A Conversa do Hearth Outra perspectiva sobre a história
Why does the World Cup in 2026 face such a different heat challenge than tournaments in the past?
The core issue is timing and geography. June and July are the hottest months in North America, and global temperatures have been rising steadily since records began in 1895. We're not just talking about discomfort—wet-bulb temperatures in places like Dallas and Houston could exceed 90 degrees, which creates genuine health risks when people are exerting themselves or sitting in the sun for hours.
What makes wet-bulb temperature different from regular temperature readings?
It factors in humidity, wind, solar angle, and other conditions that affect how the human body experiences and sheds heat. A 90-degree reading with high humidity and no wind is far more dangerous than a dry 90 degrees. It's a more honest measure of what people will actually feel and endure.
Fourteen of sixteen venues are at risk. That's almost all of them. Why not just move the tournament?
That's a fair question, but moving a World Cup is extraordinarily complicated—it involves years of planning, stadium construction, infrastructure investment, and international agreements. Qatar moved its tournament from summer to winter in 2022 specifically because of heat, but that was an exception. The preference now seems to be to manage the risk rather than relocate.
What's the most concrete protection FIFA is putting in place?
Three-minute hydration breaks at halftime, mandatory rest days between matches, and strategic scheduling—keeping outdoor matches out of the hottest hours and assigning the warmest time slots to covered stadiums when possible. It's not perfect, but it's systematic.
Does the research show these measures actually work?
That's where it gets complicated. One researcher I read noted that passive information campaigns—even multilingual alerts and real-time data—don't always change how people behave. You can tell someone to drink water and find shade, but you can't force them to do it at a large public event. The medical infrastructure helps catch people who get sick, but prevention is harder to guarantee.
What happens in 2030 when the World Cup goes to Spain, Portugal, and Morocco?
Those regions will face similar or worse heat challenges. The experts are already saying that summer tournaments are becoming increasingly dangerous as global temperatures rise. The implication is clear: eventually, the sport may have to fundamentally rethink when and where it holds its biggest events.
