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.
Just get a hygrometer to your home, and you can read the humidity levels precisely. A hygrometer is a little device that is user-friendly and inexpensive. Ideally, the humidity level between 40% and 50% is good for living. But if the temperature outside changes constantly, perhaps, you need a humidifier or a dehumidifier to maintain the right levels. The humidity level is decided by many factors, like the area and climate you are living, the season it is on, and forth.
