LONDON: The global football players’ union FIFPRO renewed concerns on Thursday regarding extreme heat risks during the 2026 FIFA World Cup across the United States, Mexico, and Canada.
According to a new study by World Weather Attribution, nearly one-quarter of the tournament’s 104 matches could take place in temperatures exceeding recommended safety levels for players and spectators.
Researchers used the Wet Bulb Globe Temperature index, which measures how effectively the human body cools itself in hot and humid conditions. The analysis showed that approximately five matches may occur under conditions considered unsafe, where postponement could become necessary.
FIFPRO medical director Vincent Gouttebarge stated that the findings support earlier warnings issued by the union in 2023 and strengthen the need for protective measures during the tournament.
Scientists Warn Heat Could Affect Matches and Fans
FIFPRO recommends cooling breaks once temperatures exceed specific safety thresholds and advises postponement if conditions become too dangerous.
Meanwhile, climate experts warned that extreme heat may significantly influence player performance and match intensity. Chris Mullington of Imperial College London explained that athletes could adopt slower and more cautious playing styles to manage physical stress caused by high temperatures.
In addition, scientists noted that several host venues without air conditioning, including Miami, Kansas City, New York, and Philadelphia, face elevated heat risks.
Reports also indicated that the final scheduled at MetLife Stadium could experience dangerous weather conditions during the tournament.
FIFA Promises Protective Measures
Meanwhile, FIFA stated that it has already developed heat-management plans to protect players, fans, referees, and staff.
The governing body confirmed that cooling infrastructure, hydration breaks, medical readiness, and adjusted work-rest cycles will be implemented based on real-time weather conditions.
Experts also urged FIFA to reconsider future World Cup scheduling in regions vulnerable to extreme summer temperatures because of growing climate-related risks worldwide.
