As the 2026 FIFA World Cup approaches, researchers highlight a growing threat: extreme heat and humidity are expected to create risky conditions for athletes and spectators at several host cities in the U.S., Mexico, and Canada, driven by climate change.
- More games at risk from unsafe heat compared to the 1994 U.S. World Cup
- Hydration breaks and rest days introduced by FIFA to protect players
- Experts call for accelerated climate action to protect sports futures
What happened
In under a month, the global spotlight will focus on the 2026 FIFA World Cup hosted across stadiums in the United States, Mexico, and Canada. A recent study conducted by the World Weather Attribution initiative has raised concerns about elevated heat and humidity levels this summer, which are projected to put athletes and spectators at risk during many matches. The analysis compares current conditions to those during the 1994 tournament and finds that dangerous heat is now nearly twice as likely, linked primarily to human-driven climate change.
Using the Wet Bulb Globe Temperature (WBGT) metric—which combines temperature, humidity, sunlight, wind, and cloud cover—researchers forecast that 26 matches will experience a WBGT at or above 26 degrees Celsius, the threshold considered risky for players' health. Among these, five matches could reach unsafe levels exceeding 28 degrees Celsius. Cities including Houston, Dallas, Kansas City, Atlanta, and New York are identified as particularly vulnerable during peak afternoon and early evening periods.
Why it feels good
Even with these challenges, FIFA and local organizers are proactive in prioritizing safety. The governing body has mandated three-minute hydration breaks in every half, regardless of weather conditions, and ensured schedules allow at least three days of rest between games to help players recover. Substitute players and staff will benefit from climate-controlled benches during outdoor matches, reducing exposure to extreme heat.
This careful planning highlights a commitment to maintaining the excitement and passion of the World Cup while adapting to evolving climate realities. The tournament represents not only a global celebration of sport but also a platform to raise awareness about climate impacts, encouraging fans and communities worldwide to support environmentally responsible practices.
What to enjoy or watch next
As the world comes together to cheer on their favorite teams, viewers can enjoy thrilling gameplay while recognizing the broader importance of addressing climate change. The 2026 World Cup follows the 2022 tournament in Qatar, which was notably moved from summer to winter months to avoid extreme desert heat—another powerful reminder of how climate affects global sports scheduling.
Looking ahead, experts emphasize the urgent need for faster climate action to protect the future of sports and all who enjoy them. Supporting clean energy transitions and sustainable practices will be key game changers. For now, fans can savor the unique atmosphere of the 2026 event, knowing the organizers are working hard to keep the beautiful game safe and enjoyable despite the rising heat.
