FIFPRO flags unsafe heat at nearly 20% of World Cup 2026 matches, raising questions about climate risk in global sports
The players' union says one in five matches exceeded its safety threshold, but FIFA's own bar for action remains significantly higher
Nearly one in five matches at the 2026 FIFA World Cup have been played under heat conditions that should have triggered delays, according to FIFPRO, the global union representing professional footballers.
As of July 16, 2026, 19% of the tournament’s 100-plus matches recorded wet bulb globe temperature (WBGT) levels at or above 28°C (82°F), the threshold at which FIFPRO recommends postponing play. Nine matches during group and knockout rounds were specifically flagged as being played under severe heat conditions by FIFPRO’s criteria. FIFA, meanwhile, doesn’t mandate cooling breaks until WBGT hits 32°C (90°F), a gap of four degrees that the players’ union considers dangerously wide.
The gap between what science says and what FIFA does
WBGT factors in temperature, humidity, wind speed, and solar radiation to estimate the actual thermal stress on a human body. It’s the metric used by militaries and occupational health agencies worldwide to determine when physical exertion becomes dangerous.
Pre-tournament modeling from World Weather Attribution had warned this exact scenario was likely. Their forecasts suggested that roughly 25% of matches could exceed FIFPRO’s safety limits, a prediction that has proven uncomfortably close to reality at 19% and counting with the tournament still ongoing.
The comparison to 1994 is instructive. The last time the US hosted a World Cup, extreme heat conditions of this frequency simply weren’t part of the equation.
Behind the scenes, the conversation is already happening
FIFA and FIFPRO have reportedly been in active discussions about heat protocols since early July 2026. Issues at the 2025 Club World Cup, also held in the US, had already surfaced concerns about player welfare in extreme heat, essentially serving as a preview of problems that would scale up dramatically when the World Cup arrived.
The union’s position is straightforward: formalized, science-based heat protocols need to replace the current reactive approach. Rather than waiting until conditions become visibly dangerous and then scrambling for solutions, FIFPRO wants predetermined rules that dictate when matches get delayed, rescheduled, or moved to cooler kickoff times.
The 2022 World Cup in Qatar was moved to November and December specifically because summer conditions were deemed too dangerous. The 2025 Club World Cup flagged heat concerns in US venues. Now the 2026 World Cup is delivering exactly the conditions that weather scientists predicted.
