Less humid, counter-intuitively is more dense and harder to push through.
Water vapor molecules are spaced farther apart than the mostly N2 O2 components of air.
Also keep in mind when you do any air density, gas law equations, temperature is Kelvin where room temperature is a cozy 293K and freezing is 273K.
