Soaring temperatures across the United States, Mexico and Canada are posing serious safety concerns for players and fans ahead of the 2026 World Cup. As reported on Channels Television, new findings warn that the heat building over the host countries could turn into a real danger during the tournament, raising fresh questions about how matches at the showpiece event should be scheduled and managed.
The warning comes as the United States has just experienced its hottest twelve-month period on the record books of the National Oceanic and Atmospheric Administration. The tournament is due to be staged across sixteen cities spread over Canada, the United States and Mexico, meaning large numbers of players and spectators could be exposed to extreme conditions at the height of summer.
According to the findings, more than a third of the World Cup games carry a heightened heat risk. Researchers estimate that over a third of the matches have at least a one-in-ten chance of exceeding a wet bulb globe temperature of twenty-six degrees Celsius, a threshold associated with a real danger of heat-related illness for those on the pitch and in the stands.
The picture is complicated by the design of the venues themselves. Cooling measures are said to mitigate some of the risk at only four of the sixteen stadiums, while a significant share of the matches flagged as high risk are scheduled to be played at venues that do not have air conditioning, leaving players and supporters more exposed to the heat.
The wet bulb globe temperature is considered a strong indicator of overall heat risk because it factors in humidity, shade and solar radiation rather than air temperature alone. Venues in cities such as Dallas, Houston, Miami and Monterrey are regularly cited as among those that experience dangerous humid heat during the June and July window in which the tournament is being held.
Climate change is identified as a key driver behind the trend, with extreme heat described as being on the rise at nearly all of the 2026 World Cup stadiums. The findings indicate that both the likelihood and the intensity of these dangerous conditions are projected to increase as the planet continues to warm, with estimated increases of around zero point seven degrees Celsius.
The research has sharpened debate over what protections will be in place for players, fans and stadium workers during the competition. Football's governing body has already taken steps to manage the heat at recent events, but the latest findings underline the scale of the challenge of staging a summer World Cup across a region where record temperatures are becoming the norm rather than the exception.
