Evaporation and Temperature

Evaporation can take place at any temperature. However, increasing the temperature of a body of water also often increases evaporation. This is because as the temperature rises, the water molecules begin moving about more rapidly. This increases the odds that molecules will escape.

Warmer air also effects the speed of evaporation. Even if a body of water is cool, warm air above the water can transport some of its energy to the water molecules, allowing them to escape more rapidly.
