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.
There are certain factors can determine what humidity level is the right one for your house. The simple answer is that a house humidity level should be somewhere between 20% and 40%. One factor that can pinpoint where your home humidity level should be is the outside temperature. As the temperature outside decreases then there is a higher risk of condensation happening inside your walls and on you windows.
