Horses have difficulty dealing with dry heat, but they have even more difficulty coping with the combination of heat and humidity. Part of the reason is that horses can cool off in dry heat through the evaporation of sweat, but in humid weather sweat just serves to insulate your horse, making him even hotter. Plus, some horses have trouble sweating (anhydrosis) during humid weather, which means they have no way to cool off at all.
