The World Cup 2026 has reached the knockout stages, and while 32 countries are battling for advancement, there’s another competitor on the field: the heat. Before the tournament kicked off across Canada, Mexico, and the United States, health experts and players were already warning that some matches might be played in dangerously hot conditions. To combat this, FIFA mandated hydration breaks during all games, no matter the temperature. As the tournament progresses, America is bracing for a significant heatwave starting July 1st that’s expected to sweep across the nation.
A report from Climate Central, a group dedicated to studying climate change, revealed that many matches have already been played under conditions that could hinder performance due to the heat. “Heat is a hidden opponent that all players are also playing against,” said Tom Di Liberto, media director at Climate Central, in an interview. The impact of heat is not uniform; it varies greatly depending on factors like game scheduling, location, and stadium conditions. This means that some national teams, unfortunately, find themselves at a greater disadvantage than others.
Take Argentina, for instance. Should they make it to the final, all their matches would be under conditions where there’s over a 50% chance that heat would negatively impact their performance. Following closely behind are Portugal, Spain, and Brazil, with about a 66% likelihood of their games being influenced by the sweltering temperatures. Just recently, the hottest match recorded was on June 30th, featuring Ivory Coast against Norway, and fans are gearing up for Argentina’s game against Cape Verde on July 4th, along with England taking on DR Congo on July 1st. Meanwhile, games like Switzerland-Algeria, Belgium-Senegal, and Mexico-Ecuador are expected to face minimal heat challenges.
It’s fascinating to consider how this situation will unfold as we progress into the round of 16, the quarterfinals, and beyond. Di Liberto points out that this conversation about heat should also extend beyond football, urging people to think about other major sporting events. “It’s a chance to put a spotlight on an issue that might not seem obvious but affects the sport we cherish,” he remarked.
Looking ahead, the Women’s World Cup in Brazil in 2027, the Olympic Games in Los Angeles in 2028, and the next men’s World Cup in Morocco, Portugal, and Spain in 2030 will likely bring this issue to the forefront once again. So, as fans, we must ask ourselves: how will teams adapt to this hidden adversary in the future?
