In order for condensation to happens, the vapor air must be

in a cooling phase

Explanation:

Condensation is the change of water from its gaseous form (water vapor) into liquid water. Condensation generally occurs in the atmosphere when warm air rises, cools and looses its capacity to hold water vapor. As a result, excess water vapor condenses to form cloud droplets. Two conditions are necessary for water vapor to condense: (1) there must be material for water vapor to condense onto and (2) air must cool to or below its dew point. When fog or clouds form, the water vapor is condensing on tiny particles called condensation nuclei (KAHN-dehn- SAY-shuhn NOO-klee-EYE).
