How hot will it be at the 2026 World Cup and is it dangerous for players and fans?

Researchers have warned of a 'real risk' of unsafe heat conditions at the 2026 FIFA World Cup, which will be hosted across 16 stadiums in the US, Canada, and Mexico. The US National Weather Service's seasonal outlook predicts above-historical-average temperatures across the country in June and July, with Miami identified as the city most likely to expose players and fans to dangerously stressful heat levels. The Guardian's analysis compares current meteorological conditions to those experienced during the last North American World Cup in 1994, when the US was the sole host nation, noting significant climate changes in the intervening three decades.
