North America’s Summer Weather Could Be the Toughest Opponent at the 2026 World Cup
The 2026 World Cup is underway, and every one of the 48 teams is facing an unexpected rival: the summer weather across North America. From Mexico to Canada, matches are spread across 16 cities, each bringing its own risks—thunderstorms, heat, humidity, and even tropical storms.
Thunderstorms have already caused trouble. England’s warm-up against Costa Rica in Orlando was delayed about an hour when lightning and heavy rain left the pitch waterlogged. U.S. safety rules stop play if lightning is detected within eight miles of a stadium, and action can’t resume until 30 minutes after the last strike.
The biggest storm threats are in the central, eastern, and southeastern U.S. Miami and Houston are the most lightning-prone, though Houston’s stadium has a retractable roof. But the next few days bring the highest risk to the northeast, with scattered storms packing strong gusts and hail. That puts Friday’s Canada-Bosnia match in Toronto, plus Saturday’s games in Boston and New York, at slight risk.
Heat and humidity may be the biggest challenge for players and fans. Monterrey, Mexico, sees high temperatures, but the humid southeastern U.S. can cause even greater heat strain at lower temperatures. FIFA uses Wet Bulb Globe Temperature (WBGT) to measure heat stress, which combines temperature, humidity, solar radiation, and wind. Many experts see 28°C WBGT as unsafe for intense play; FIFA’s threshold for action is 32°C. A 2025 study found that 14 of the 16 host cities will hit 28°C at least sometimes, though several stadiums have roofs and air conditioning.
Tropical storms are another worry. The tournament falls early in the Atlantic season, so storms are more likely to form in the warm Gulf of Mexico, Bay of Campeche, and western Caribbean, putting Mexican venues, Houston, and Miami at greatest risk. The National Hurricane Center is tracking a low-pressure area over the Bay of Campeche, giving it a small chance of becoming a cyclone before hitting eastern Mexico this weekend.
Mexico City adds a different challenge: its altitude of about 2,240 meters means thinner air, which speeds up fatigue and slows recovery for players. It also changes how the ball moves.
Canada’s venues should stay cooler and face the lowest storm risk. The uneven spread of these conditions has already sparked questions about competitive fairness.
