The reason the air around the surface of the water got cooler is because of evaporation. Since the water evaporated, the energy (and heat) decreased. Since the heat from the water decreased, so did it's surroundings. Basically, this is endothermic. (Because it gave off energy to it's surroundings.) So in conclusion, the air got cooler because of it's endothermic enegry.
