2026 World Cup: Extreme Heat Threatens Players
15 Jun
Summary
- A quarter of matches could exceed safe heat limits.
- Heat risk probability has nearly doubled since 1994.
- FIFA implements 3-minute hydration breaks per half.
Extreme heat poses a major threat to the 2026 FIFA World Cup, with studies predicting that approximately 25 percent of the 104 matches could surpass crucial thermal safety thresholds. The analysis by World Weather Attribution (WWA) highlights a near doubling of the risk of facing such conditions compared to the 1994 World Cup.
Using the wet-bulb globe temperature (WBGT) to assess heat stress, the study examined host cities in the United States, Mexico, and Canada. FIFPro, the players' union, has set a WBGT index of 26° Celsius as a threshold for extra hydration and 28° C as high risk, warranting match delays or suspensions.
Miami, Kansas City, Philadelphia, Dallas, and Houston are identified as cities with a particularly high probability of experiencing 28° C WBGT conditions annually during the tournament dates. This increased risk is linked to global warming, with average global temperatures having risen significantly since 1994.
In response to these warnings, FIFA will implement three-minute hydration breaks at the midpoint of each half. However, experts advocate for further preventive strategies, including modified warm-up schedules, enhanced stadium cooling infrastructure, and more rigorous medical supervision for all involved.
