"Playing in this temperature is very dangerous." That's Chelsea midfielder Enzo Fernandez, who had to lie down on the pitch during last summer's Club World Cup after a dizzy spell from the heat. That tournament was the dress rehearsal. The main event kicks off next week.
The 2026 World Cup — spread across 16 cities in Mexico, Canada and the United States over 38 days — is walking into a climate crisis with its eyes open and its scheduling choices questionable. Thunderstorms knocked out power near Kansas City just hours after Lionel Messi's Argentina squad arrived at their training base. That was before a ball had been kicked.
The numbers are genuinely alarming
A 2025 study in the International Journal of Biometeorology found that 14 of the 16 host cities are likely to exceed the extreme Wet Bulb Globe Temperature threshold — the index that measures actual heat stress on the human body, not just the number on a thermometer. In Miami, where seven games will be played, 90-degree air temperature "feels like" 109 degrees once humidity is factored in. At that point, sweating — the body's primary cooling mechanism — stops working effectively.
"These are the kinds of situations where you have to be really careful," said Kaitlyn Trudeau of Climate Central. "Not just players, but also people who maybe work at the stadiums, people who are watching the matches. It can be a very dangerous situation."
Some climatologists believe summer tournaments are one heatwave away from a major tragedy. That's not hyperbole — it's the considered view of researchers who study this for a living.
FIFA's scheduling choices don't help
FIFA has added mandatory three-minute hydration breaks midway through each half. Fine. They've also scheduled 40 of the tournament's 104 games — including most knockout matches — to kick off at 3 p.m. local time or earlier. Those two decisions sit in direct contradiction with each other.
"That's kind of silly," Trudeau said. "We're going to give an extra water break, but we're going to be doing it at the hottest time of the day. What is the main priority of FIFA here? Is it to get the most views and the most revenue? Or is it to actually protect these players?"
FIFA, for its part, says it has a tiered heat-mitigation model — cooling buses, misting systems, shaded areas, scaled dynamically based on real-time conditions. Three venues in Atlanta, Houston and Arlington are domed and climate-controlled. The other 13 are not.
The commercial logic behind those 3 p.m. kickoffs is obvious: European TV audiences. The sporting logic is harder to defend when your players are visibly suffering.
- Global June temperatures have risen 1.89°F since the first World Cup in 1930, per NOAA data
- 14 of 16 host cities expected to exceed extreme heat stress thresholds during the tournament
- 40 of 104 games scheduled for 3 p.m. kickoff or earlier, despite peak afternoon heat
- Last summer's Club World Cup saw half a dozen matches paused or delayed by storms and lightning
- FIFA President Infantino is already discussing moving future tournaments to March or October
The 2030 World Cup, hosted primarily in Spain, Portugal and Morocco, will face the same problem with almost none of the infrastructure to handle it — just one likely venue is climate-controlled, and temperatures in those regions regularly exceed 95°F in June and July.
Elliot Arthur-Worsop of Football For Future puts it plainly: by the time the hosting cycle could realistically return to North America, "our climate projections show that the tournament in its current form would be unplayable due to extreme weather events. Not only heat, but other compounding threats such as extreme wind and flooding and wildfires."
"We're running out of options," Trudeau said. The 2026 World Cup may be remembered as the tournament that finally forced football to reckon with that reality — or, worse, as the one where something went badly wrong.
