The 2026 FIFA World Cup could be remembered not only for what happens on the pitch, but also for the extreme weather surrounding the tournament. Heat, humidity and severe thunderstorms are already raising concerns, with experts warning that this could become one of the most climatically challenging World Cups in decades.

The hottest World Cup in decades? And not because of the atmosphere in the stands…

Meteorologists warn that the tournament could become the hottest World Cup since 1994, when the United States last hosted the competition. Back then, many matches were played in the afternoon, and extreme temperatures had a significant impact on the quality and intensity of play. One of the most memorable examples was Mexico’s match against Ireland in Orlando, where temperatures at pitch level reportedly reached as high as 47°C (117°F).

This time, organizers are trying to avoid similar scenarios, but weather conditions remain one of the biggest challenges facing players, fans, and security services.

Dallas Stadium and Estadio Monterrey among the hottest venues

Analysis of historical weather data suggests that the highest temperatures are likely to be recorded at stadiums in the southern part of North America. Venues in Dallas and Monterrey are expected to be particularly exposed to extreme heat.

Dallas Stadium, which will host one of the tournament’s semifinals, could experience average temperatures above 32°C (90°F). On the hottest days of the competition, temperatures may climb to around 34°C (93°F). Fortunately, the stadium features a retractable roof and an air-conditioning system, significantly improving conditions for both players and spectators.

A similar situation applies to some other modern venues, but many World Cup stadiums will remain open-air facilities. At those venues, high temperatures could become one of the key factors influencing matches. The large capacity of the stadiums means that tens of thousands of fans must be accommodated simultaneously. Under extreme heat, the risk of dehydration, fainting, and other health-related incidents increases considerably.

Meteorologists also point out that temperatures at field level are often much higher than those recorded by official weather stations. The playing surface absorbs solar radiation and releases heat, while limited air circulation inside the stadium can further intensify uncomfortable conditions.

Cooling zones and water stations planned for stadiums

FIFA and the host cities have announced a range of measures designed to reduce the impact of high temperatures. Planned initiatives include dedicated water distribution points, cooling zones, industrial fans, and misting systems.

Organizers have also stated that water prices inside stadiums will remain in line with standard rates charged during other events held at the same venues. However, not everyone is convinced. Experts argue that the real challenge will be the number of water stations available and the length of the queues. Even the best-prepared infrastructure may prove insufficient if tens of thousands of people attempt to use it at the same time.

FIFA changes water bottle rules for World Cup 2026 stadiums

The expected heat has turned stadium beverage policies into one of the most debated issues ahead of the tournament. FIFA initially decided to tighten regulations by banning reusable bottles and flasks from stadiums. The organization argued that such items could pose security risks at major events.

The decision immediately drew criticism from supporters’ groups and the media. Critics argued that restricting access to water during a summer tournament could negatively affect spectator health, especially for those waiting hours to enter stadiums.

Following the backlash, FIFA partially reversed its position. Fans attending matches in the United States and Canada will now be allowed to bring one factory-sealed plastic bottle of water into stadiums. The bottle may not exceed 590 milliliters in capacity. Metal bottles, thermoses, and rigid reusable containers will remain prohibited. FIFA maintains that the revised policy represents a compromise between security concerns and spectator comfort, although not everyone is satisfied with the solution.

Storms over Mexico City could disrupt World Cup matches

Experts warn that severe thunderstorms could pose an even greater challenge than the heat itself. This concern is particularly relevant for Mexico City, where June and July often bring afternoon downpours accompanied by lightning.

North America follows strict weather safety protocols. If lightning is detected within approximately 13 kilometers (8 miles) of a stadium, the match must be suspended immediately. Play can only resume at least 30 minutes after the last detected lightning strike.

Heat, storms, and humidity could affect match results

Weather conditions may play a much larger role during the 2026 World Cup than many fans expect. High temperatures reduce playing intensity, increase player fatigue, and make it more difficult to maintain a high tempo throughout the full 90 minutes.

In addition, storms and weather-related delays can affect match rhythm, tactical preparation, and player recovery. Under such conditions, success depends not only on footballing ability but also on a team's capacity to adapt to challenging environmental circumstances.

The 2026 World Cup could therefore become a tournament in which the weather proves to be as formidable an opponent as any rival on the pitch. Organizers are doing everything possible to minimize the impact of extreme heat and severe weather, but the real test will begin when the opening whistle blows.

Estadio Ciudad de México and the weather forecast for the World Cup opener

Particular attention is focused on the weather expected for the opening match at Mexico City Stadium. According to meteorological forecasts, fans should prepare not only for warm temperatures but also for rain.

Before kickoff, temperatures are expected to range between 22°C and 24°C (72–75°F), with partly cloudy skies and moderate winds. During the match, light rainfall is forecast, with temperatures reaching around 26°C (79°F).

The biggest challenges may come after the final whistle. Meteorologists are forecasting heavy rainfall in the southern part of the city, along with wind gusts of up to 45 km/h (28 mph). As a result, thousands of fans leaving the stadium could face transportation disruptions.
