World Cup 2026: Heat Danger Warning for Players and Fans

Researchers have warned there is a “real risk” of unsafe conditions at the 2026 World Cup, with matches in Miami most likely to be affected. The tournament will take place across 16 stadiums in the US, Canada, and Mexico. The National Weather Service predicts every part of the US will experience temperatures above the historical average in June and July. This is the environment where 48 men’s national teams will compete for the World Cup. The Guardian has analyzed the meteorological conditions players could face, how they have changed since the last North American World Cup in 1994, and which locations pose the greatest heat risk. The picture is mixed across the host cities, but experts say extreme heat could be dangerous for both athletes and fans.
