World Cup Heat Sparks Safety Concerns

Several first-round World Cup matches have been played under severe heat conditions, with at least two games exceeding the 28C wet-bulb temperature threshold that the global players' union, Fifpro, has previously stated should trigger delays. Saudi Arabia's match against Uruguay in Miami and Sweden's game against Tunisia in Monterrey were among those played in the most extreme heat among the first 24 games analyzed.

Wet-bulb temperatures, which combine air temperature, humidity, and cloud cover to measure heat stress, reached 28C or above in six of the initial 24 matches. While air conditioning in some stadiums and later kick-off times helped mitigate conditions, experts like Robbie Parks from Columbia University warn that conditions for fans and stadium workers remain hazardous.

Fifa has implemented measures such as hydration breaks and air-conditioned venues. However, a group of heat and public health experts urged Fifa to adopt more extensive protections, including shade and allowing fans to bring water, citing extreme heat as the deadliest climate crisis hazard. The tournament itself is also projected to significantly increase greenhouse gas emissions.

A Fifa spokesperson stated the organization is committed to health and safety, employing meteorologists and a tiered mitigation model for extreme temperatures. This includes additional cooling for spectators and a medical protocol for heat exertion. Fifa monitors conditions in real-time and is prepared to activate contingency plans if extreme weather occurs.
