We have an excessive heat watch right now so the temperature will be between 113-115. I won’t ride when it’s this hot! Instead, I hose my mare off and give her time off.
I’m a PE teacher so I teach my students to be cautious about sugary drinks like Gatorade but I feel it’s necessary when you are outside in hot weather. There are days where I chug water all day but still have an unquenchable thirst. I often pack Gatorade for trips to the barn and believe it helps me.
I found a chart not too long ago that was titled “Is it too hot to ride?” and was graphed based on heat index, humidity, temperature etc. I want to try and find it.
