South Florida’s mixture of sturdy solar, hot-air temperature, and excessive humidity—boosted by a plume of dusty air from the Sahara desert sweeping throughout the Atlantic by way of the state—will put the northern European gamers beneath a stage of warmth stress not often skilled of their native international locations.
Scientists quantify this warmth stress by calculating the WetBulb Globe Temperature. On high of air temperature, the index takes under consideration humidity, which limits evaporation of sweat from the pores and skin; wind, which might act as a coolant; and photo voltaic depth, as sunshine straight raises people’ pores and skin and core temperatures.
Saturday’s match is forecast to be performed at an especially excessive WBGT of round 88 levels Fahrenheit (31 levels Celsius).
