The wet-bulb temperature is a better indication of how deadly the temperature is as it's equivalent to the temperature that humans can obtain by losing body heat from sweating/evaporation. A wet-bulb temperature of 35C is pretty much the upper limit that humans can survive for a sustained period and 32C is considered "extreme risk".
