Penn State researchers found that the maximum wet-bulb temperature humans can endure is lower than previously thought — about 31°C wet-bulb or 87°F at 100% humidity — even for young, healthy subjects. The temperature for older populations, who are more vulnerable to heat, is likely even lower.
I think they say you can survive 140 degree surface temperature? if you're otherwise well hydrated and in the shade and the humidity is low. Evaporative cooling works really well if your surroundings are dry and you don't dehydrate or let your electrolyte balance go out of wack.
