Therefore 60 % Relative Humidity on a hot day means the air is very humid and uncomfortable
However, on a cold day, in absolute terms, the air contains much less water vapor
This is why your home seems so dry in the winter when you run the furnace – because it is! The outside humidity may be 75 or 80% at 40° but will only be 45 to 50% inside in the warm 72° - Drink more fluids in the winter!!!
