Top Scientists Warn of Extreme Weather Risks at 2026 FIFA World Cup

Leading scientists have raised alarms about the potential risks of extreme weather during the upcoming 2026 FIFA World Cup. They deem FIFA’s current heat safety measures as insufficient for safeguarding players and others involved.
Concerns Over Heat Safety Measures
In an open letter addressed to FIFA, a coalition of international experts specializing in health, climate, and sports performance criticized the governing body’s guidelines. They state these practices are not only outdated but also “impossible to justify” under contemporary scientific standards.
Recommendations for Enhanced Protections
The scientists advocate for stronger protective measures, including:
- Extended cooling breaks for players.
- Clear protocols for delaying or postponing matches under severe weather conditions.
Heat Risks in Host Cities
Heat is expected to be a significant concern for the tournament scheduled across the United States, Canada, and Mexico. Research indicates that temperatures at 14 out of the 16 stadiums may reach perilous levels.
In many regions of the southern U.S. and northern Mexico, average daytime temperatures often fall within the low to mid-30s Celsius. During particularly hot spells, these values can soar toward 40°C.
Factors Influencing Heat Stress
When factors such as temperature, humidity, wind speed, and sunshine intensity are considered, the risk of heat stress for players in these host cities is alarmingly high.
FIFA’s Commitment to Safety
In response to these concerns, FIFA has expressed its commitment to protecting the health and safety of everyone involved in the tournament, including players, referees, fans, volunteers, and staff. They have stated that they assess climate-related risks during tournament planning.
Given these warnings from the scientific community, it is clear that enhanced measures are critical to ensure player safety during the 2026 World Cup.
