Can the dew point temperature be more than drybulb temperature?
Dew point gives an indication of the moisture content of air; it is the temperature at which air can no longer hold water vapour.

The following graph shows the relations of dew point to air temperature (dry bulb) for various levels of humidity.



For humidity less than 100 percent, the air temperature is always higher than the dew point temperature and for a humidity of 100 percent air temperature equals the dew point temperature.

The dew point cannot be higher than the dry bulb temperature, it can only be lower of equal to it.
