Water vapour would have to come out of the atmosphere in the liquid form if the air were to be cooled still further, which would typically happen as fog or precipitation. In colder months, the optimal indoor humidity range is 30 to 40 percent. Humidity is the amount of water vapor in a given volume of air. The moisture in a dirt-floor basement can be as high as 100 percent, depending on how damp the soil is, and that moisture can filter up into other areas of the home. Liquid water evaporates from oceans, lakes, rivers, plants, the ground, and fallen rain. [2] Humidity indicates the likelihood for precipitation, dew, or fog to be present.

One still should be able to carry on ordinary outdoor activities. For example, if the temperature is 100F, you would first subtract 32 from 100, which would give you 68. Water vapor, the gaseous state of water, is generally invisible to the human eye. If it is raining heavy (like in the outer parts of a hurricane), shouldn't the humidity level be 100%? No water will evaporate from the wet bulb at 100 percent relative humidity, and the readings on both thermometers will be the same.
