Keeping this in mind, Is humidity higher in summer or winter? Relative humidity, a percent of saturation, is temperature dependent. Since cold air holds substantially less moisture than warm air, it is easier to saturate a parcel of cold air. Consequently, relative humidity is actually higher in winter than in summer (76% vs. 66%, according to climatology).
What is an uncomfortable humidity level?

The reason is temperature. Warmer temperatures can hold more moisture than colder temperatures. … it is temperature that makes all the difference; cold winter air, even when saturated, contains far less moisture than warm summer air.
