Experts warn fans and players face 'danger levels' of heat and humidity at World Cup

Climate change is increasing the risk of extreme heat and humidity during the 2026 FIFA World Cup, according to World Weather Attribution (WWA). Their analysis shows that 25% of the 104 matches—including the final in New York and New Jersey on July 19—could exceed a 26°C wet bulb global temperature (WBGT), a level where protective measures like cooling stations are advised. Five games may face even more dangerous conditions above 28°C WBGT, equivalent to 38°C dry heat or 30°C humidity, prompting FIFPRO to call for postponements. The warnings follow complaints from last year’s Club World Cup, where players like Chelsea’s Enzo Fernandez reported dizziness from extreme heat. England manager Thomas Tuchel has already considered keeping substitutes indoors due to high temperatures. A group of 20 climate scientists, including experts from the UK, USA, Canada, Australia, and Europe, signed a letter urging FIFA to delay matches above 28°C WBGT, introduce six-minute cooling breaks, and improve cooling facilities. WWA’s findings highlight that half of human-induced climate change has occurred since the last US-hosted World Cup in 1994. Dr. Friederike Otto, a climate scientist at Imperial College London, stated that the risk of cancellation-level heat during the final serves as a ‘wake-up call’ for FIFA and fans. The letter emphasizes that climate change impacts all aspects of society, including major sporting events. FIFPRO’s medical director, Dr. Vincent Gouttebarge, confirmed the estimates align with their 2023 research, reinforcing the need for mitigation strategies. The tournament spans the US, Mexico, and Canada, where heat risks vary but require unified safety protocols. Experts stress that proactive measures are essential to protect player health and performance amid rising global temperatures.
