Extreme heat and high humidity are expected to impact several matches during the 2026 FIFA World Cup, creating health risks for players and fans.
These conditions are critical because they may exceed safe thresholds for athletic performance and spectator comfort, potentially forcing organizers to alter match schedules or safety protocols.
The tournament is scheduled to run from June 11 [1] to July 12, 2026 [1]. Southern venues in the U.S. and Mexico are most at risk, including Dallas, Houston, Atlanta, Miami, and Mexico City [1, 3].
Forecasts indicate maximum temperatures could reach up to 40 °C (104 °F) [1] at some venues. Other projections suggest temperatures could exceed 38 °C (100 °F) [2] during peak match windows.
Humidity is expected to be a significant factor, with projected levels between 70% and 80% [2]. "We could see temperatures exceeding 38 °C (100 °F) with humidity above 70% during peak match windows," Marshall Shepherd said [2].
Climate scientists link these projections to broader environmental shifts. "Climate change is turning what used to be a summer tournament into a potentially dangerous heat event," Dr. Emily Rivera, a climate scientist at the University of Texas, said [1].
FIFA officials have acknowledged the challenge. "The health and safety of players and fans is our top priority," Dr. Michael Johnson, FIFA Chief Medical Officer, said [3].
Organizers must now balance the logistical demands of a massive international event with the physical limits of human endurance in extreme weather, a challenge exacerbated by the geographic spread of the tournament across North America.
“"Climate change is turning what used to be a summer tournament into a potentially dangerous heat event,"”
The intersection of a global sporting event and extreme weather highlights the increasing difficulty of scheduling outdoor athletics in a warming climate. If FIFA is forced to implement emergency cooling breaks or shift kick-off times to late night, it could disrupt global broadcasting schedules and ticket logistics, signaling a shift in how international sports are managed in the era of climate change.
