Players and spectators face risks from extreme heat and humidity, which can lead to heat-related illnesses. Thunderstorms may disrupt matches, particularly in lightning-prone areas like Miami and Houston. Severe weather, including strong winds and hail, could impact games in Toronto, Boston, and New York. Tropical storms present additional risks for venues in Mexico and the southeastern U.S. Mexico City's high altitude adds another layer of difficulty, as reduced oxygen levels can accelerate fatigue and alter ball dynamics.
