In an earthen pot, water gets evaporated quickly through the pores. Cooling is caused by evaporation. Some heat energy is utilised during the process of evaporation. Since this energy is taken from the water itself, it leads to a lowering of temperature in the remaining amount of water.

Earthen pots have very tiny pores on them from where the water seeps through out and slowly evaporates.
This evaporation causes cooling effect in the surface of the pot which ultimately causes the water to cool down.
Since evaporation causes change in state of water therefore it needs more energy to change it's state. This extra energy is taken in the form of heat energy from the surrounding area causing the area to become cool.
