Every World Cup has its favourites, its underdogs and its surprises. But the 2026 tournament has an opponent that does not appear on any team sheet, wears no colours and cannot be substituted: the brutal North American summer heat. From the deserts of the American Southwest to the humidity of the Gulf Coast, the conditions have become a defining factor of the tournament — and European teams, in particular, are struggling to adapt.

The Heat Is Real

Playing football at the highest level is demanding in any conditions. Playing it in extreme heat and humidity — sometimes in temperatures that would prompt health warnings for ordinary activity — is another challenge entirely. Players are losing significant fluid, tiring faster, and finding that the intensity they can sustain in European conditions is simply not possible in the North American summer.

The teams that manage the heat will go far. The teams that don’t will go home — no matter how talented they are.

How European Teams Are Coping

European nations, accustomed to milder summer conditions, have had to adapt their preparation and tactics. Teams have adjusted training schedules to acclimatise players, modified their playing styles to conserve energy, and made strategic use of the cooling breaks that have become a regular feature of matches. England, for instance, undertook specific heat preparation in Florida before the tournament.

The tactical implications are significant. The high-pressing, high-intensity styles favoured by many European teams are extraordinarily demanding in the heat. Teams that can control possession, conserve energy and pick their moments to attack have a natural advantage over those that try to play at a relentless tempo.

The Scheduling Controversy

The scheduling of matches — with some games played in the hottest parts of the day to suit European television audiences — has been a source of controversy. Player welfare advocates have raised concerns about the risks of competing in extreme heat, and the debate about balancing commercial interests with athlete safety has been a recurring theme of the tournament.

A Glimpse of the Future

The heat challenges of the 2026 World Cup offer a glimpse of football’s future in a warming world. As climate change makes extreme heat more common, the question of how and when football can safely be played will become increasingly important. The 2026 tournament is, in this sense, a test case for the sport’s adaptation to a changing climate.

Who Benefits?

The teams best suited to the heat may have a genuine advantage. Nations from hot climates — many African, Asian and Central American teams — are more accustomed to the conditions. South American sides, too, have experience of heat and humidity. The traditional European powers, for all their quality, face a genuine challenge in adapting to conditions that are simply not part of their normal footballing environment.
