Weather Risks Impact World Cup 2026

The 2026 FIFA World Cup, hosted across 16 cities in the United States, Mexico, and Canada, faces significant weather-related challenges impacting player safety and match schedules. These challenges include thunderstorms, extreme heat and humidity, and the potential for tropical storms, with varying degrees of risk across host cities.

Thunderstorms have already caused disruptions, exemplified by a one-hour delay during England's warm-up match in Orlando due to lightning and heavy rain. U.S.

safety regulations mandate suspensions when lightning is detected within approximately eight miles of a stadium. Miami and Houston are identified as the most lightning-prone host cities, though Houston's stadium features a retractable roof.

The greatest risk for severe storms in the coming days is projected for the northeastern U.S. and southeastern Canada, potentially affecting matches in Toronto, Boston, and New York.

Heat and humidity pose a broad challenge, particularly in the southeastern U.S. and Monterrey, Mexico.

FIFA utilizes the Wet Bulb Globe Temperature (WBGT) index to assess heat stress, with 28C WBGT considered unsafe for high-exertion play by many physiologists. A 2025 study projected that 14 of the 16 host cities will exceed 28C WBGT at times.

Additionally, the early Atlantic hurricane season increases the risk of tropical storms for Mexican venues, Houston, and Miami, with a low-pressure area currently monitored over the Bay of Campeche. Mexico City's altitude of approximately 2,240 meters presents further challenges due to reduced oxygen availability affecting player performance.
