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.
What is the ideal amount of humidity indoors? Maintaining an indoor relative humidity of approximately 45 percent is the ideal level for the summer months or warmer climates. Colder climates or the winter months require even lower levels, approximately 30 to 40 percent. Indoor air quality is regarded as one of the top environmental threats by the EPA.
