Hot, dry deserts have very low moisture content, so the specific humidity (the actual amount of water vapor in the air) would also be very low during the daytime. The relative humidity (the amount of water vapor in the air compared to how much it could hold at a given temperature) may be higher at night when temperatures drop and the air can hold less moisture, but during the daytime, it would be low. Saturation vapor pressure (the pressure exerted by water vapor in the air when it is fully saturated) would likely be high since the hot air can hold more moisture, but not low. Lifting condensation level (the altitude at which an air parcel would become saturated and form clouds) and mixing ratio (the ratio of the mass of water vapor to the mass of dry air in a sample) are not directly related to humidity levels.
