The most frequent winds are from the West. During the spring and autumn, southern winds are responsible for massive precipitation. During winter, winds from the north or east bring dry and cold days; sometimes their interaction with wet tepid masses from the Atlantic or Mediterranean creates the conditions for heavy snowfall. Foehn is a fall or winter wind that can provoke sudden higher temperature. The main local winds are: "Breva dal Segrin" (from the south), "Breva da Caslin" (from the west), "Vent dal Sant Prim" (from the north), and "Ariasc di Alp" (from the east).
