Scorching heat and sudden thunderstorms have caused significant disruption at the Club World Cup, raising concerns over similar conditions expected during the 2026 men's World Cup in North America.
As a severe heatwave blankets much of the eastern United States, players and coaches have been forced to adapt their routines to cope with the punishing temperatures and humidity.
In an unusual move, Borussia Dortmund left their substitutes inside the dressing room for the first half of their match against Mamelodi Sundowns in Cincinnati, sparing them from the blistering sun on the bench. Meanwhile, Chelsea's coach Enzo Maresca cut short his side's training session in Philadelphia as temperatures soared to 37.2C 99F.
Dortmund's manager, Niko Kovac, stressed the impact of the weather on the tournament's outcome, stating: "I believe this tournament will not be won by the best team, but by the one best able to handle these conditions."
Alongside mandatory cooling breaks at halftime, teams have taken extra precautions to mitigate the oppressive heat. Kovac highlighted the medical support provided, saying, "Our players receive excellent care from our medical staff. We use cold towels, ice baths for the legs and feet - all to help them cool down."
