Instead of using humidity directly we use dew point to measure what people commonly mean when saying it feels humid. Dew point is classified into 4 categories: Dry (under 25°F), Comfortable (25°F to 60°F), Muggy (60°F to 70°F) and Oppressive (70°F or greater). The table below shows the percentage of days with a dew point within a particular class.
