How the North American heatwave could impact the FIFA World Cup

The 2026 FIFA World Cup is facing significant challenges as a powerful heat dome brings furnace-like conditions to large parts of the United States and Canada. Temperatures are expected to exceed 43 degrees Celsius (110 F) in several host cities, raising concerns about player and fan safety during the tournament's knockout stages.

Authorities have issued warnings for upcoming matches. In Toronto, fans attending the Portugal vs. Croatia match are urged to stay hydrated and limit alcohol intake, as humidity could make temperatures feel like 40C (104F). Friday's match between Colombia and Ghana in Kansas City will be played under an extreme heat warning with "feels like" temperatures up to 43C (110F). Miami and Philadelphia are also bracing for high temperatures and heat risks this weekend.

temperatures could feel like 40C (104F) because of the humidity.

While stadiums in Atlanta, Dallas, and Houston are equipped with retractable roofs and air conditioning, many venues offer limited protection. Approximately 43,000 fans in Toronto, and tens of thousands more in Philadelphia and Kansas City, will be exposed to direct sun. Organizers are providing shade, misting stations, and cooling zones, but built-in climate control is absent in these locations.

The heat poses risks even before reaching the stadium. In Dallas, pavement temperatures outside venues could reach 50C (122F), making the walk from parking or public transport significantly hotter than the air temperature. FIFA has already shortened operating hours for its Fan Festival in Philadelphia due to the heat.
