This is colloquially referred to as the "misery" index. And the number is
(I think, but wouldn't swear to it) 150. HOwever, it is of dubious value,
especially at lower temperatures. (E.g. the ambient temperature is 50
degrees and the himidity is 100%...it's raining. Horses in such
situations are unlikely to suffer from overheating. They are far more
likely, in fact, to get chilled.)
THey will, mostly likely, (at least their riders will) be miserable.
