Best Answer: With all other things remaining the same, relative humidity will increase as temperatures decrease. Since relative humidity is a ratio (in percent) of the actual amount of water vapor in the atmosphere compared to the saturation amount, if the saturation amount decreases, the ratio must increase.

Best Answer: Ah Judy, there isn't such a thing as an average relative humidity. This is because it changes a lot only in the course of the day. How much moisture the air can contain depends on the temperature. The warmer it is, the more moisture it can contain. That is the absolute humidity that is the volume of water per volume of air. The relative humidity, which is what you measure with a hygrometer, is the percentage of moisture to achieve full saturation for a given temperature. But since the temperature varies a lot during the course of a day, so does the relative humidity.
