According to Wikipedia[1]:
"Even heat-adapted people cannot carry out normal outdoor activities past a wet-bulb temperature of 32°C (90°F), equivalent to a heat index of 55°C (130°F). The theoretical limit to human survival for more than a few hours in the shade, even with unlimited water, is 35°C (95°F) – theoretically equivalent to a heat index of 70°C (160°F), though the heat index does not go that high."
So the practical limit is indeed much lower than 35°C; that's the limit at which you're basically going to fall over and die.
