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.
Check your house's humidity meter to see if you need to adjust the humidity in your home. In most temperatures, humidity up to 35 percent is safe. In temperatures below 20 degrees Fahrenheit, it is important to further reduce the humidity to as low as 15 percent. Look for signs of your humidity being too high.
