> Winter air tends to be much drier than summer air

Where I lived before, that's still 80% (usually 90-95% in summer)

That's relative humidity, not absolute. Absolute humidity has an additional Arrhenius (https://en.wikipedia.org/wiki/Arrhenius_equation) factor. For instance, 100% relative humidity at 40 C is 51.1 g/cm^3, while at 20 C it's only 17.3 g/cm^3.
