Humidity
Actually Antarctica is a desert, it's arid with only about five percent humidity. Plus it is exceptionally cold. By comparison, the Sahara desert in Africa is rated at from 25% to 30% humidity.
The relative humidity would be quite low.
this is the current humidity
The ideal indoor humidity level according to the humidity chart in Fahrenheit is around 30-50.
The entire continent is considered a desert, because the humidity there is about five percent.
Average humidity on the Antarctic continent is less than five percent: it is a desert.
The desert is usually not humid unless it happens to be during the rainy season. I live in the desert and yesterday our humidity was 2% with a dewpoint of minus 26 degrees F. That is about as dry as one can find.
All of Antarctica is a 'polar desert' because the humidity there is less than five percent. The humidity in the Saraha desert is 25% to 30%. Any latitude below 60 degrees South latitude that lies on a continent is a latitude of the Antarctic desert.
