When talking about a certain day feeling 'muggy' or 'sticky,' the dew point temperature is the more accurate term to use. In short, the dew point is an accurate measurement of the moisture content in the air. The National Weather Service defines dew point as the temperature to which air must be cooled to in order to reach saturation, assuming air pressure and moisture content are constant. Get the latest forecast from the CBS2 New York weather team. The further apart these values are, the lower the humidity.ĭew point is the term that most meteorologists use to describe the amount of moisture in the air.

Without explaining the equation variable by variable, we can simply state that the relative humidity is determined by how close the air temperature is to the dew point temperature. Relative humidity is calculated using meteorological variables such as vapor pressure, saturation vapor pressure, temperature and dew point. Furthermore, the higher the relative humidity, the closer the dew point to the current air temperature, with. Dew points below 50 are dry, dew points between 50 and 65 are sticky but not unbearable and anything above 65 is very humid. In the summertime, dew points are a useful measure of humidity (much more so than Relative Humidity). Dew point varies depending on the amount of water vapor present in the air, with more humid air resulting in a higher dew point than dry air. The dew point is the temperature at which the air would be fully saturated (100 RH) and capable of forming dew (or frost, if its cold enough). Explore > Could Niagara Falls completely freeze? Dew is the condensed water that a person often sees on flowers and grass early in the morning.
