There are wide thermal amplitudes within the semi-arid mountain climate that characterizes the area. From the west, the high Andean peaks work as a barrier against the humid and cold winds from the Pacific. And from the East, the Pampa mountains soften the force of the Atlantic winds, decreasing humidity.
