temperature influence the evaporation and condensation
At the room temperature, water particles move faster
The lower the temperature, the less particle will move
the higher the temperature, the more water will evaporate

The absence of wind will slow down the rate of evaporation.
The presence of wind will never influence the rate of evaporation.
The absence of wind will increase the rate of evaporation.
