The vast unbroken stretch of ocean to the west and south of the South American continent leaves the Patagonian Andes very exposed to the saturated winds that circle the Antarctic landmass. Also, both the strong marine and the South Patagonic Icefield influence makes the weather hard to predict. In spring or early summer fine weather may deteriorate almost without warning, bringing rains and eventually snow. Even in summer (December to march) you should come prepared to find cold- strong winds (up to 130 km/hr) and rainfalls. The summers average temperature is 11ºC/52ºF (24ºCmax, 2ºC min).
