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.

| Dry | 24.7 | 31.7 | 24.0 | 6.2 | 0.2 | 1.0 |
