Comments here on the temperature fail to add WBT is related to a high humidity. 'The wet-bulb temperature (WBT) is the temperature read by a thermometer covered in water-soaked (water at ambient temperature) cloth (a wet-bulb thermometer) over which air is passed.' https://en.wikipedia.org/wiki/Wet-bulb_temperature https://en.wikipedia.org/wiki/Wet-bulb_temperature Edit: because a high humidity means the body cannot cool anymore by sweating. A higher temperature combined with dry air is generally not a life threatening situation (if you stay in de shade and drink a lot of water).
