The extreme heat and humidity expected in several host cities could pose health risks to players, staff, and fans, particularly during daytime matches. High-altitude venues like Mexico City may also challenge teams unaccustomed to such conditions, potentially affecting stamina and performance. Fans traveling between venues will face logistical hurdles, including long distances and varying climates, which may add to the physical and financial strain. The Guardian notes that these factors could influence match outcomes, favoring teams with strong possession-based playstyles and those better acclimated to the conditions.
