This World Cup, hosted across the United States, Canada, and Mexico, is experiencing significant weather challenges. It is the warmest edition since 1994, with many games played above 90F (32C). Extreme heat, humidity, and thunderstorms are affecting match play and logistics. A thunderstorm protocol mandates suspensions if lightning is detected within an eight-mile radius, leading to 30-minute countdowns that reset with new strikes. The game between France and Iraq was the first to be delayed by storms, stopping for over two hours. The Athletic is collaborating with meteorologist Aaron Mentkowski to provide daily forecasts. Looking ahead to the Spain vs Argentina match at MetLife Stadium, leading up to the World Cup final in New York City, an Air Quality Alert is in effect due to wildfire smoke from Canada. Hot and hazy conditions are expected, with rain and cooler temperatures forecast for the weekend, potentially clearing the smoke before Sunday's match.
