Relative humidity % is a highly misleading measure of the level of discomfort due to humidity. Most people don't realize that there is an inverse relationship between RH % and temperature. I.e., assuming the actual amount of moisture in the air is the same, RH% goes down as temperature goes up and vice versa.

Dew point is a much better measure of uncomfortable humidity.

All I know is I was dripping with sweat by 0630 just making a lunch for Mr. "the Knife", and taking a shower is useless because I am sweating again before I even dry off! Humidity, dew point - how about I just say that it has been really muggy the past few days and today promises more of same! 😅😅😅

Doesn’t matter. In western WA few people have air conditioners, so anything over 80 is uncomfortable!

That's funny! I spent several hours yesterday trying to understand this 3 way relationship and I have to say I still don't have a simple understanding of how to "calculate" the discomfort. But I am surprised that people continue to use the reported RH as the gauge of discomfort.

Input two out of the three numbers: temperature, dew point and relative humidity and it will calculate the third.
