Toronto experienced scorching heat and humidity during the final World Cup game between Portugal and Croatia. The weather conditions approached the “wet bulb” threshold recommended by global soccer guidelines, leading to concerns about player safety. Previous matches in the tournament had already been delayed due to extreme heat.
In downtown Toronto, the temperature dropped to 27 degrees Celsius with 67% humidity by the 7 p.m. kickoff time. Earlier in the day, a heat dome over southern Ontario and Quebec pushed temperatures to a high of 35 degrees Celsius, with the humidity making it feel like 42. The intense heat prompted the cancellation of a popular public viewing event for World Cup matches at Nathan Phillips Square.
FIFPRO, the worldwide organization representing professional footballers, has issued guidelines for extreme heat based on the wet bulb globe temperature (WBGT). According to these guidelines, games should be delayed or postponed if the WBGT exceeds 28 degrees Celsius or if the ambient temperature goes above 36 degrees Celsius to ensure the safety of players, officials, and fans.
The wet bulb globe temperature considers the cooling effect of sweating on the body. When humidity levels are high, sweat evaporation is slower, hindering the body’s ability to cool down effectively. This can lead to heat-related illnesses, such as heat stroke or exhaustion, posing risks to athletes and workers.
While there is no specific temperature threshold set by FIFA for match postponement, concerns about player health in extreme conditions have been raised. FIFPRO will address heat-related issues affecting players in more detail at an upcoming news conference. Despite adjustments to the match schedule to mitigate health risks, challenges remain due to competition formats and infrastructure constraints.
It is crucial to monitor for signs of overheating, such as dizziness or lightheadedness, and take precautions to stay safe in hot and humid conditions, whether actively participating in sports or spectating.
