Up to one in four matches at the 2026 FIFA World Cup could be played in dangerous heat conditions, a new report warns. The analysis identifies Miami, Kansas City, Philadelphia, Dallas, and Houston as particularly high-risk host cities.
The report examines climate data for 16 venues across the United States, Canada, and Mexico. It finds that extreme temperatures could threaten player safety and match integrity during the tournament, which runs from June to July.
Dallas and Houston face the highest risks, with forecasted heat index values exceeding 90 degrees Fahrenheit. These conditions can lead to heat exhaustion, cramps, or more severe heatstroke for athletes.
Miami and Philadelphia also pose significant concerns due to high humidity and heat. Kansas City, while less extreme, still registers dangerous levels during peak summer afternoons.
The findings highlight a growing challenge for global sports events in a warming climate. Organizers may need to adjust kickoff times or implement cooling breaks to mitigate risks.
Beyond player safety, extreme heat could impact fan experience and stadium operations. Spectators exposed to prolonged heat face similar health dangers, especially in uncovered seating areas.
The 2026 World Cup will be the first to feature 48 teams and 104 matches across three nations. The report underscores how climate change is reshaping the logistics of major international tournaments.
