I know what you mean, I grow indoors and outdoors.
What I do outdoors is partially shade my plants. This works well.
I use 2 by 2 sticks 2 inches apart, eight feet above the plants (Like a patio cover) during the hot months and spray water on the ground around them.
If you are going to grow next year you should build a shade like this for them. If you use small nails you can easily remove them when the temps drop a bit.
