It's marginally tolerable if there's wind but when the air is still you literally have minutes before it's too much, you have to stay moving to keep sweat evaporating. it's all the same above about 108, you just can't do it for any meaningful length of time. You can spend a few minutes in the sun and retreat to shade, but you'd be feeling pretty shitty in even half an hour unless you're taking other measures like wetting yourself or constantly sipping cold water or misting or whatever. I moved a wood pile the other day while the air was still and felt like I was going to die but then I started pressure washing and felt great.
