How can you tell if the temperature is above or below the dew point?

You can determine if the temperature is above or below the dew point by comparing the two values. If the air temperature is higher than the dew point, the air is dry, and no condensation occurs. Conversely, if the temperature is lower than the dew point, the air is saturated, leading to potential condensation, fog, or precipitation. A simple way to remember this is that the dew point represents the temperature at which air becomes saturated with moisture.
