Six key host cities for the World Cup 2026—Miami, Houston, Dallas, Monterrey, Kansas City, and Atlanta—face the daunting prospect of extreme heat stress during afternoon matches. The Wet Bulb Globe Temperature (WBGT) in these locations could soar to 32°C (90°F) or higher, pushing players’ bodies to their limits as they struggle to regulate core temperature under intense heat.
Scheduling Matches to Beat the Heat
To combat these hazardous conditions, organizers strategically schedule games beyond the peak afternoon heat. Many matches kick off in the late afternoon or evening, minimizing players’ and spectators’ exposure to extreme temperatures. For instance, Scotland’s Group C clash against Brazil in Miami is set for 18:00 ET (23:00 BST), deliberately timed to avoid the worst heat of the day.
Climate-Controlled Stadiums Provide Relief
Some venues, notably those in Houston and Dallas, boast retractable roofs and advanced climate control systems. These features help maintain safer, cooler environments inside stadiums, shielding athletes and fans from oppressive outdoor heat.
Heatwaves Amplify Risks Across North America and Mexico
Summer heatwaves, a recurring challenge across North America and Mexico, can drive temperatures up by 10°C (18°F) or more above seasonal averages. This spike escalates risks for players and supporters alike, potentially pushing conditions into dangerously extreme territory.
Consider New York, host city for this year’s World Cup final on 19 July at 15:00 ET (20:00 BST). A typical heatwave could push air temperatures into the mid-30s Celsius (mid 90s Fahrenheit), with WBGT values approaching 30°C (86°F). Such conditions markedly increase the likelihood of extreme heat stress, demanding vigilant safety measures.
