To determine the Dew Point from the charts below, find the temperature of the air in question on the left side of the table. Next, locate the relative humidity of the air in question across the top of the table. The intersection of these two numbers in the matrix identifies the temperature at which Dew Point is reached. For example, in the table below at relative humidity 35%, air temperature 24oC the Dew point temperature is 7 degrees C.

When air comes in contact with a surface that is at or below its Dew Point temperature, condensation will form on that surface.
