What level of humidity is uncomfortable?

Forecasters watch the dew point, not relative humidity, because hot air can hold more moisture than cool air. At 90 degrees, we feel uncomfortable at dew points of 65-69 degrees. But the RH may be only 44 – 52 percent (half the atmosphere’s capacity). Dew points above 70 degrees feel oppressive.

Surprisingly, yes, the condition is known as supersaturation. At any given temperature and air pressure, a specific maximum amount of water vapor in the air will produce a relative humidity (RH) of 100 percent. Supersaturated air literally contains more water vapor than is needed to cause saturation.

Is 0 humidity possible?

Has the relative humidity ever dropped to zero percent? … The concept of zero percent relative humidity — air devoid of water vapor — is intriguing, but given Earth’s climate and weather conditions, it’s impossible. Water vapor is always present in the air, even if only in minute quantities.
