FIFA has introduced mandatory cooling breaks as the 2026 World Cup faces extreme weather threats across North America. With temperatures potentially reaching 40°C (104°F) in host cities, concerns grow about player welfare during the tournament, which kicks off in just one month.

Heat stress measurements reveal critical risks, with WBGT readings potentially exceeding safe levels in 14 of 16 host locations. Cities like Miami, Houston, and Dallas could experience extreme heat stress conditions, forcing organizers to schedule matches during cooler evening hours despite the logistical challenges.

Thunderstorms present another significant disruption risk, with play automatically suspended for at least 30 minutes when lightning is detected within 10 miles. Wildfire smoke affecting air quality adds another unpredictable element, potentially leading to delays or cancellations based on real-time conditions and public health advice.
