At What Temperature Does Your Horse Start to Get Cold?
Horses will start feeling cold below certain critical temperatures. For a clipped horse, or one with a summer coat, the average critical temperature is 40°F. For horses with a thick winter coat, the critical temperature can be as low as 18°F.
Once a horse’s coat becomes wet, the critical temperature will increase by anywhere from 10°F to 15°F. For example, a dry horse will stay warm until the temperature goes below 18°F, while a wet horse will begin to get cold at 33°F.
When monitoring the outside temperature, always consider the effects of wind chill and use that as your lowest temperature. Remember, smaller horses, seniors, horses in a new environment, or underweight individuals, may be more sensitive to the cold than a big stout horse.
