WebThe dew point is the temperature the air needs to be cooled to (at constant pressure) in order to achieve a relative humidity (RH) of 100%. At this point the air cannot hold more water in the gas form. If the air were to be cooled even more, water vapor would have to come out of the atmosphere in the liquid form, usually as fog or precipitation.

WebThe hydrocarbon dew point is the temperature (at a given pressure) at which the hydrocarbon components of any hydrocarbon-rich gas mixture, such as natural gas, will start to condense out of the gaseous phase. It is often also referred to as the HDP or the HCDP. WebThe dew point, however, remains constant. The dew point and relative humidity are the same at 100%. But below 100%, it is the dew point that will indicate how hot and humid the day feels. For example, it might be 90°F/32°C with humidity at 52%. But the dew point is 70°F/21°C which means it will feel almost unbearably uncomfortable.
