A phenomenon of the region of Aysén are the 4 climatic zones within 150-200 km. of distance between the Pacific coast and the Argentine pampa crossing over the Andes.
The pacific coast with its islands and fiords is one of the areas with a lot of precipitation (comparable to Pto. Montt, Chaitén, Puyuhuapi, Pto. Cisnes, Pto. Aysén, Pto. Grosse and Tortel).
Coming to our location about 40 km. away from the coast there is only about the half of the amount of rain left.
Along the Carretera Austral (comparable to Cerro Castillo, Pto. Tranquilo, Pto. Guadal, Pto. Bertrand and Villa O'Higgins) the climate is more dry.
Towards and in Argentina predominates the dry pampa with little rain (comparable to Pto. Ibañez and Chile Chico).
