Mexico opens the 2026 FIFA World Cup against South Africa on Thursday at Estadio Azteca with weather already threatening to shape the first kick of the tournament. The match is set to start at 1pm local time in partly sunny conditions, but the forecast turns far less forgiving as the afternoon goes on.
By 3pm local time, the rain and storm chance near the stadium is expected to climb close to 80 percent, with temperatures around 75F. Mexico supporters expected inside Estadio Azteca will be watching the sky as much as the ball, because the opening match could move from a summer afternoon into a storm delay before it is even over.
That risk carries extra weight in a World Cup spread across the United States, Canada and Mexico, where extreme heat, humidity and thunderstorms are expected to be part of the tournament’s backdrop. The 2026 event is also likely to be the warmest World Cup since the last edition held in North America in 1994, adding another layer of strain to a schedule built around 104 games.
The concern is not only the forecast over Mexico City, which sits 7,350 feet above sea level, but how quickly a match can be stopped once lightning enters the picture. In the United States, a game must be suspended if lightning or electrical discharge is detected within an eight-mile radius of the stadium, and the clock starts a 30-minute countdown that resets if another strike is detected before it ends.
Last summer offered a reminder of how long that can take. Chelsea’s Club World Cup match against Benfica in Charlotte, North Carolina, lasted four hours and 38 minutes after repeated lightning delays. That kind of stop-start chaos is not what anyone wants on opening day, but it is the backdrop for a tournament where the weather can change the rhythm of a match as quickly as a red card.
The first question now is whether Thursday’s opener can get through the afternoon without a suspension. Mexico and South Africa are due to begin at 1pm local time, and if the storm threat keeps building as expected, the opening game could become the first real test of how the World Cup handles the weather it has inherited.
