World Cup Heat: 1 in 5 Games Ignored Safety Thresholds

Nearly one in five matches during the recent World Cup were contested under heat and humidity levels that previously warranted delays or postponements. An additional 23 games took place in cities experiencing these conditions, even with stadium air conditioning. This situation underscores the intensifying challenge posed by the climate crisis to professional football, making extreme heat events more frequent and severe.

The World Cup has served as a stress test for heat mitigation strategies, revealing complications arising from extreme weather. While Fifa has implemented measures like mandatory hydration breaks and provided cooling amenities, concerns persist regarding player and spectator safety. The players' union has previously stated that games should be postponed in such conditions, emphasizing the need for future tournament scheduling to account for a warming planet.

Official measurements for heat stress, known as Wet Bulb Globe Temperatures (WBGT), consider humidity, sunlight, and wind. Approximations indicated that around 20 matches exceeded the 28C (82F) WBGT threshold. The hottest game, played in non-air-conditioned conditions, reached WBGT levels potentially above 33.9C (93F). Even air-conditioned venues did not fully shield attendees from extreme external temperatures.

Further risks include degraded air quality from wildfire smoke, impacting attendees. The article also points to concerning conditions outside venues, such as long walks in unshaded areas and exposed seating, increasing heat stress risks for spectators. Future World Cups are anticipated to face similar challenges, with upcoming tournaments scheduled in regions already experiencing extreme heat.
