Its not uncommon to have above 90% relative humidity readings. I find it uncomfortable once the humidity is over 70%, but I'm really not a 'good' test subject as I have lived in Florida all my life and have gotten use to high humidities. I can tell you one thing with certainity, the insects love the high readings! 60% is a threshold in the summer.
Similarly, if the relative humidity rises above 60 percent most people can sense it. In the range of 25 percent to 60 percent the majority of people cannot sense any difference. The range of 25 percent to 60 percent is typically defined as the comfort range for this reason.
