At the most they can be equal when the air is saturated. Othewise the dew point will always be less than the air temperature(particularly in the case of unsaturated air).The pressure exerted by the water vapour is only a part of the total air pressure and thus it can never be more than that and the dew point of air is the temperature for which the saturation vapour pressure is identical with actual pressure of the vapour in the air.When volume of air is not taken into cosidearation, the temperature is proportional to pressure(PV=RT).As vapour pressure is always less than air pressure, dew point temperature should also be less than air temperature.

The dew point will never be higher than the air temperature. Here's why: The dew point temperature is the temperature to which air must be cooled (at a constant pressure and constant water vapor content) for saturation to occur
