Ahead of the 2026 FIFA World Cup across the United States, Canada and Mexico, multiple outlets report that extreme heat and volatile weather are likely to affect when and where games are played. A briefing cited by Inside World Football from UN Climate Change links rising extreme heat events to changes in how sport is experienced, including match scheduling and on-pitch demands. Scientific American highlights that heat risks extend beyond players to spectators and event workers, and discusses practical measures aimed at reducing danger. Al Jazeera reports that climate experts estimate roughly 25% of World Cup games could be played in very hot conditions. Inside World Football provides a more specific estimate, saying extreme heat could affect 26 out of 104 matches. Sky Sports frames heat as an additional challenge alongside factors such as tactics and pressure. Several sources also note that playing in hot summer conditions is not new in parts of the United States and point to earlier tournament experience, including limited adaptations during USA 1994, as a reference point for how organisers may respond. Overall, the reporting focuses on the expected prevalence of dangerous heat conditions and the need for cooling and safety planning.
