Average annual dew point.
This measure has no better end. The order describes the states, it does not rank them — see the other direction.
Average annual dew point temperature, the amount of water vapour in the air expressed as the temperature at which it would condense. Higher dew points feel muggier; unlike relative humidity, dew point remains comparable between cold and hot places. Sampled at the county population centroid from PRISM's 4 km annual grid, so it describes typical local air rather than a county-wide average.
Florida has the highest published humidity in this comparison, at 65.2°F. The next states shown are Louisiana (60.4°F) and Mississippi (56.6°F).
The table orders 49 states by average annual dew point. It describes one published measure, not an overall judgment about where to live.
Use the result as a starting point, then compare the underlying source, dates, and local county figures before making a decision.

Not ranked, because this measure is not published for them: Alaska, Hawaii. PRISM currently publishes this grid for the contiguous U.S. only; Alaska and Hawaii are blank rather than assigned a statewide substitute.
Free to use. The chart names its source and links back, so it stays honest wherever it ends up.
