As a frame of reference, I trial & error’ed several temp + humidity combinations, and the resulting wet-bulb temperatures.
“The wet-bulb temperature is the lowest temperature that can be reached under current ambient conditions by the evaporation of water only. 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 (131 °F).” (Wikipedia).
For those who don’t know, wet-bulb index of 95 is widely accepted by scientists as the limit beyond which human beings can theoretically only survive for a few hours.
But, now experts are saying that even 88 or above can be dangerous — even for healthy young people.
Here are three sets of temperature & humidity values that I input, and the resulting wet-bulb temperatures:
99F, 87% humidity –> wet-bulb 95.65 (deadly range)
94, 87% –> 90.76
94, 80 –> 88.58
