When Is It Too Hot to Ride? Staying Safe in the Saddle During Summer Heat

Summer is here! The days are longer, the kids are off school, and many riders are eager to spend more time at the barn and in the saddle. However, with summer in our area comes rising temperatures. We are the stewards of our horses’ well-being, and we must ask a critical question: when is it too hot to ride?

Heat affects both horses and riders, and riding in extreme temperatures is dangerous and can lead to serious health risks. Whether you’re a weekend trail rider or a competitive athlete, understanding how heat affects you and your horse is essential to keeping both of you safe.

Understanding Heat Stress in Horses

Horses are incredibly athletic, but they’re not immune to the dangers of high temperatures. A horse’s body is approximately 70% muscle, and during exercise, it generates a tremendous amount of heat. Their primary way of cooling down is through sweating, just like humans. But if it’s too hot or humid, sweating becomes less effective.

When Is It Too Hot?

To determine if it is too hot to ride, you must be able to calculate the heat index. Many people think this is as simple as adding the temperature and humidity together. That is not true. The formula is long and complicated and can be found here>>>. Thankfully, NOAA (National Oceanic and Atmospheric Administration) has created a simple chart.

How to Read the Chart

Look for the temperature across the top, then find the relative humidity on the left. The point where they intersect on the chart indicates the Heat Index, color-coded by the likelihood of a heat disorder. This is only possible if you know the humidity. Modern phones display the temperature, but how do we determine the humidity? In my barn, I have a temperature and humidity meter.

Tips for Riding Safely in the Heat

If you decide to ride when it’s warm, follow these best practices:

1. Ride Early or Late

Avoid the hottest part of the day (typically 11 AM to 4 PM). Early morning or evening rides are cooler and more comfortable.

2. Stay in the Shade

If you are fortunate enough to have a covered arena, it makes riding on hot days far more comfortable. If not, then try to ride in the shade.

3. Lighten the Load

Stick to light work, such as walking, light trotting, or groundwork. Save more intense training for cooler days.

4. Hydrate—Horse and Rider

Ensure your horse has access to clean, cool water before and after your ride. Electrolytes can also help replenish lost minerals.

5. Cool Down Properly

After a ride, sponge or hose your horse with cool water and walk them out in the shade. Focus on large muscle groups and the jugular groove.

6. Listen to Your Horse

Every horse handles heat differently. If your horse is sluggish, breathing hard, or sweating excessively (or not at all), it’s time to stop.

It is vital to avoid overheating at all costs, but it is also essential to recognize the signs in case they occur.

Signs of Heat Stress in Horses:

• Rapid breathing or panting
• Excessive sweating (or sudden lack of sweat—anhidrosis)
• Elevated heart rate that doesn’t return to normal quickly
• Lethargy or unsteadiness
• Dark urine or signs of dehydration (e.g., dry gums, slow capillary refill)

Don’t Forget the Rider

You are also part of the equation. Riders can suffer from heat exhaustion or heat stroke just as easily. Watch for signs like dizziness, nausea, excessive sweating, or confusion. Stay hydrated, wear light, breathable clothing, and take breaks in the shade.

Final Thoughts

Riding in the summer can be a joy—but not at the cost of your or your horse’s health. Use common sense, know the warning signs, and when in doubt, skip the ride. There’s no shame in trading your saddle time for some hand grazing, a refreshing bath, or a quiet grooming session.
