It's not just about the temperature, but also (and sometime even more) about humidity. We had mid 90-th this week, which doesn't sound too bad, but with the very high humidity it was impossible to ride even in eve or early morning.
However 112F is very high even with the low humidity IMHO. Especially for the older horses.
