Fifpro Warns 9 World Cup Matches Crossed Dangerous Heat Thresholds as US Heatwave Builds
2 articles · Updated · The Guardian · Jun 30
Summary
Nine of the World Cup’s 72 group-stage matches were played in severe heat that Fifpro says should trigger delays or postponements, based on Guardian estimates of wet-bulb globe temperatures at or above 28C.
33C WBGT may have been reached at Miami’s Hard Rock Stadium during Uruguay’s 2-2 draw with Cape Verde on 21 June, topping the tournament’s previous estimated high set six days earlier at the same venue.
An additional 13 matches may have exceeded that heat level in host cities but were played in air-conditioned stadiums; only Dallas, Houston and Atlanta have fully cooled venues.
Fifa says it is using a tiered heat-mitigation model with three-minute hydration breaks, meteorologists and cooling measures, but it did not say what WBGT would automatically force a delay or suspension.
One in four matches could be played at 28C WBGT or higher by the tournament’s end, with a fresh heatwave set to hit open-air host cities including Philadelphia, Kansas City and Boston this week.
With experts calling FIFA's heat rules inadequate, will future World Cups be forced to move to the winter?
Is the World Cup's extreme heat a climate crisis, or a complex weather event that science cannot yet fully attribute?
Are air-conditioned stadiums the only real answer for protecting players and fans at major sporting events?
Extreme Heat and Climate Change Threaten 2026 FIFA World Cup: Player Safety, Economic Risks, and the Future of Global Sports
Overview
As the 2026 World Cup unfolds, significant concerns have emerged about player safety due to dangerous heat thresholds. International experts have criticized FIFA’s existing guidelines, calling them out of step with current science and impossible to justify. These experts are urging stronger protections, such as longer cooling breaks and clearer protocols for delaying or postponing games. The assessment of heat risk relies on Wet Bulb Globe Temperature (WBGT) thresholds, and analysis shows several matches are likely to breach these critical levels. This situation highlights the urgent need for FIFA to update its heat mitigation strategies to protect players.
