How hot is too hot to ride?
Horses have a higher natural body temperature than humans. Horses have hair. Horses heat up faster while exercising than humans do. So if you’re hot, your horse is definitely hot. So when do you decide it’s too hot for pony time in the saddle?
My solution to riding on hot days is to ride early or ride late. For a few years when I had an anhidrotic horse, the solution was ride at midnight. I didn’t bother riding yesterday, but Tuesday I got on at 7:30pm and this evening I’m thinking I might not get on until 7:45 or 8pm. When it’s 100 degrees F at 6pm there’s just no way. That’s dangerous, in my mind, for me and my horse, to try to ride in that kind of heat.
