This is why relative humidity is rather meaningless when it comes to how you feel. Dew Point: The dew point is the temperature at which the vapor of a liquid forms the first bubble of liquid or dew, commencing the condensation of vapor.

There’s a lot more water in the 50-percent full container. Bubble Point: The bubble point is the temperature at which a solution makes the first bubble of vapor, commencing the vaporization of that solution (at constant pressure). Think about the difference between an 8-ounce glass of water that’s full and a swimming pool that’s half full.

Hot air with a relative humidity of 50 percent has half the potential moisture, but because the air can hold so much water vapor, there’s a lot present. So when you have 100 percent relative humidity in cold air, the air is full of moisture, but the air molecules are packed tighter and there’s not much space in there for water vapor.
The issue is, if the air is cold, the potential for total moisture is small. A relative humidity of 50 percent means the air is half full of potential moisture. The higher the dew points, the higher the moisture content of the air at a given temperature. A relative humidity of 100 percent means the air is full of the potential moisture. Dew points indicate the amount moisture in the air. The term “relative humidity” tells you little about how much actual moisture is in the air it only tells you how close the air is to being full of water vapor. The molecules of cold air are packed tighter together and can’t “hold” as much water vapor.
