Wet bulb is the temperature of the air along with factoring in for the humidity present in the air.
The amount of heat the human body can endure is directly impacted by it’s ability to reduce its temperature via sweat. Now sweat works by cooling the body when it evaporates off of the skin. When humidity is so high it impedes sweat from evaporating it becomes much more dangerous because the body is unable to cool itself. This is why the heat can be tolorable at 100 degrees in the desert, but the same temperature will kill you in a swamp.
