Dew point versus relative humidity
WebDEW POINT Dew point is the temperature at which moisture will condense on a surface. No coatings should be applied unless the surface temperature is a minimum of 5°F above this point. EXAMPLE If the air temperature is 70°F and the relative humidity is 65%. The dew point is 57°F. The coatings should not be WebSep 3, 2024 · The dewpoint is always lower or equal to the air temperature, hence why dew or fog often occurs during the early morning hours, when the air temperatures are typically lowest and the dewpoint highest. On the other hand, the relative humidity is the ratio …
