Two matches in the World Cup, held in Miami and Monterrey, were played under severe heat conditions that a players' union previously indicated should lead to delays or postponements. An analysis revealed that six of the first 24 matches occurred in locations where wet-bulb temperatures reached 28°C or higher, prompting discussions about player safety and health protocols.
FIFA has implemented measures such as later kick-off times and mandatory water breaks to address the extreme heat. However, experts have called for more extensive protections for players and fans, emphasizing the need for shade and hydration as temperatures are expected to remain high throughout the tournament.
