The sweltering heat that's engulfed North America this week is set to sizzle its way into the World Cup, leaving players and fans alike sweating bullets. A blistering heatwave is intensifying across central and eastern regions of the United States and Canada, with air temperatures forecast to soar into the high 30s Celsius - and in some areas, a scorching 40C isn't out of the question. The National Weather Service (NWS) has issued dire warnings, cautioning that the 'feels like' temperature could reach an alarming 46C in parts of the Southern Great Plains, mid-Mississippi valley, and even the mid-Atlantic.
For World Cup stars, this means potentially life-threatening conditions on and off the pitch. The global players' union, Fifpro, has a strict set of rules governing what it considers 'unsafe' playing temperatures - and unfortunately for fans, several matches are set to fall under that umbrella. France versus Sweden in New Jersey on Tuesday is one of them, expected to reach a balmy 30C; Portugal against Croatia in Toronto on Thursday will be sizzling at 31C; Argentina versus Cape Verde in Miami on Friday will also hit the high 30s; and Colombia versus Ghana in Kansas City on Friday will push temperatures to an eye-watering 32C.
And it's not just the temperature that's a concern - humidity levels are set to make conditions feel even more oppressive. The 'feels like' temperature could reach a stomach-churning 40C at matches in Miami and Kansas City, where high humidity will make the heat feel almost unbearable. And with the official Wet Bulb Global Temperature (WBGT) measure for both games potentially approaching Fifpro's safety threshold, it's clear that something needs to be done to protect players.
Fifa has taken steps to mitigate the impact of the heatwave, introducing climate-controlled benches and offering a range of cooling measures at outdoor matches. But with temperatures set to peak over the weekend, it remains to be seen whether these precautions will be enough to keep players safe - and fans comfortable. The heat may slightly ease by then, but 'feels like' temperatures for two crucial last-16 games could still exceed 40C, making it a high-stakes battle between safety and sportsmanship.
