Unless it is very wet and windy, horses tolerate cold much better than heat and humidity. If they can’t sweat, they can’t get rid of heat buildup in their bodies. If the sum of the temperature in degrees Fahrenheit and the relative humidity in percentage is over 130, you should be cautious about exercising your horse. If it is over 150, you should probably rest in the shade, and if it is over 180, most horses should not work at all.
