The human body utilizes the effect evaporation for cooling. Hence the water on the body surface make the skin to experience chilly as the wind blows to evaporate it. As the latent heat of vaporization is extracted from the body, it is cooler in the process. This is the same reason why perspiration cools the body as the sweat evaporate from the surface of the skin.
