During evaporation of a liquid the molecules of liquid having high kinetic energy move out off the surface of the liquid leaving behind the molecules with low kinetic energy. ...

Evaporation is the process of conversion of water (liquid) to the water vapor (gaseous state). When liquid changes to gaseous state it absorbed some heat or energy from surrounding that decrease the temperature of surrounding and causes cooling effect.
One of the live example is sweating. In hot summer days, sweat evaporate causes cooling effect that balance the temperature of body.
Hence, evaporation is effective process that balance our body temperature in hot sunny days.
