Condensation
Relative humidity increases
The dew point is reached when the temperature falls to the point where air becomes saturated with water vapor and can no longer hold it, causing condensation to form. At this point, the air is said to be at 100% relative humidity.
Dew point is the temperature at which air becomes saturated with water vapor and condensation begins to form. You know the temperature has reached its dew point when water vapor in the air begins to condense into liquid water, such as dew on the ground or fog in the air.

Condensation occurs when air reaches its dew point, which is the temperature at which air becomes saturated with moisture and can no longer hold it in gaseous form. When air cools to its dew point, water vapor in the air condenses into liquid water, forming dew or fog.

Dew point. At this point, the air can no longer hold all of the water vapor it contains, leading to condensation and potential formation of clouds or fog.
When a parcel of air is cooled to the temperature at which it is saturated, it has reached its dew point temperature. At the dew point temperature, the air is holding the maximum amount of moisture it can hold, and any further cooling will result in the formation of water droplets or condensation.
