How Hot Is Too Hot to Ride a Horse? 

Riding your horse in hot weather requires careful consideration of various factors to ensure both your and his safety and well-being.

Long days and warm weather make summer a great season for riding. Some days, however, the heat can be downright unbearable. In fact, you might be wondering if it’s even safe to be in the saddle. So in this article, we’ll explain the risks of riding in extreme heat and help you assess whether it’s too hot to ride your horse. 

The Dangers of Riding in Very Hot Weather 

Riding in excessively hot weather can pose serious risks to both you and your horse. When temperatures soar, your horse is at risk of: 

  • Heat stress: Just like humans, horses can suffer from heat stress, leading to fatigue, dehydration, and heatstroke. But they’re even more susceptible to heat stress (three to 10 times more!) than we are.
  • Dehydration: High temperatures can rapidly deplete your horse’s fluids, affecting his overall health and performance. 
  • Heatstroke: Severe heat can cause your horse’s body temperature to rise drastically, leading to potentially life-threatening conditions. 

Understanding these dangers is the first step to making informed decisions about riding in hot weather. 

Understanding the Heat Index 

Ambient temperature alone does not tell the true tale of how hot it really feels. That’s why you want to consider the heat index—a measure that combines air temperature and relative humidity—when deciding whether it’s too hot to ride a horse. Humidity can significantly impact your horse’s ability to cool down.  

To calculate the heat index: 

  1. Look up the current air temperature and relative humidity. You should be able to find this information easily on a weather app or website. 
  1. Input those two figures into an online heat index calculator or reference a heat index chart.

For instance, if the temperature is 90°F and the humidity is 70%, the heat index would be approximately 105°F—much hotter than the air temperature alone would suggest.

How Hot Is Too Hot to Ride Your Horse? 

So, at what point does the heat become too much for safe riding?  

A combined temperature and humidity value (heat index) greater than 150 starts to become risky. If the heat index is above 180, it’s generally considered unsafe to ride. 

These values serve as general rules, but always consider your horse’s unique characteristics and health status. 

Other Factors to Consider 

When determining whether to ride in the heat, also take into account the following factors: 

Horse Fitness 

Well-conditioned horses might handle heat better than ones that are less fit. Monitor horses with any history of respiratory or cardiovascular issues closely. 

Acclimation to Climate 

Horses accustomed to cooler climates might struggle more in sudden hot weather compared to those living in warm areas year-round. If moving or traveling to a warmer climate, allow your horse time to adjust gradually. 

Time of Day 

Early mornings and evenings are generally cooler and safer for riding. Midday temperatures are usually the highest, so avoid riding during this peak period. 

Shade and Water Availability 

Ensure there’s plenty of shade available to cool down in after your ride. And keep your horse hydrated before, during, and after riding. 

Equipment and Gear 

Use tack that doesn’t trap heat. Opt for lighter colors, and avoid insulating materials like synthetic pads and neoprene. Consider using cooling blankets or neck wraps on both yourself and your horse. 

Take-Home Message 

Riding your horse in hot weather requires careful consideration of various factors to ensure both your and his safety and well-being. If you do go for a hack on a hot day, stay hydrated, monitor your horse for signs of heat stress (e.g., heavy sweating, rapid breathing, and lethargy), take frequent breaks in the shade, and keep the ride short and easy. And when in doubt, err on the side of caution, and wait for a cooler day to ride.
