Humidity

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.

	Jan	Feb	Mar	Apr	May	Jun
Dry	60.9	59.3	32.2	9.7	0.3	0.0
Comfortable	39.1	40.7	67.8	89.8	77.9	46.2
Muggy	0.0	0.0	0.0	0.5	21.5	44.3
Oppressive	0.0	0.0	0.0	0.0	0.3	9.4
