Riding in 30 degree(celsius) weather?

Okay I live in Oklahoma and the hottest it gets in the summer is around 100 and are horses are perfectly fine in this weather. I know 70 degrees is hot to northern states and countries. I use to live in michigan. Of course then I didn't have horses. But I'll says that in our version of hot we ride in early morning or late afternoon when its cooled off enough. We make sure our horses have plently of water while out riding. And horses have an amazing way of cooling off their bodies if they get to warm. So don't worry about it getting to hot.Your horse will adjust. Try to ride in the shade if you can that helps also. SO remember lots of water and breaks and some shade if you can,
