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

Researchers warn of a ‘real risk’ of unsafe conditions, with matches in Miami most likely to be affected, but the picture is mixed across the 16 stadiums

It’s set to be hot in North America this summer. The “seasonal temperature outlook” for the US, compiled by the National Weather Service, suggests every part of the country will experience temperatures above the historical average in June and July. It’s into this environment that 48 men’s national teams will arrive, all competing to win the World Cup in the US, Canada and Mexico.

As the tournament approaches, the Guardian has taken an in-depth look at the meteorological conditions players could face, how they have changed since the last time the World Cup was held in North America in 1994 (when the US was the sole host nation), and the locations most likely to expose players to stressful levels of heat.
