Seems like some helpful information to share!
Heat and humidity have returned to the Midwest! Horses can acclimate to hot and humid weather conditions; however, air temperature and relative humidity can affect your horse’s ability to cool themselves.
It is recommended to avoid (or use caution when) riding or exercising a horse when the combined air temperature (in Fahrenheit) and relative humidity (%) surpass 150. For example, if the temperature is predicted to be 92 F with 69% relative humidity, the combination of the two is 161.
When the air temperature + relative humidity is less than 130, horses are very effective at cooling themselves. Between 130 and 150, a horse’s ability to cool themselves is decreased. When the combination is greater than 150, a horse’s ability to cool themselves is greatly reduced, and if the combination is greater than 180, conditions could become fatal if the horse is stressed.
