The weather is continental cold with dry season. An important rain variation is produced from west to east. Temperatures markedly slow down from the slopes to the top of the mountains. In winter, middle temperature is between 2 to 4ºC and during summer it can climb up to 14 to 18ºC. This climatic variation plus different soils and reliefs comes to important changes in vegetation and fauna. Winds blow from norwest to southeast very often, though it is not strange if in autum dry and cool ones came from the east.
