Good point pheets! Adjustments must always be made to meet the specific summer conditions of each horse owner’s location, and tolerances of the horses. I am located in Michigan, so a lot of humidity, and a few summer days of 90, but they are the exception, not the rule, and last year & probably this summer, we may even have fewer than normal 80 days. Some of the ramifications of global warming are the opposite of what one would expect. Also, my turn-out areas either have a decent amount of shade, or have almost constant light breezes, both of which make a difference.
