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, the influence from the strong marine currents and Southern Patagonian Ice field make the weather hard to predict.
In Torres del Paine in spring or early summer fine weather may deteriorate almost without warning, bringing rains and possibly snow. Autumn can also be unpredictable and winter is bitterly cold. Even in summer (December to March), cold strong winds (up to 130 km/hr) and rainfall are not uncommon. The summer’s average temperature is 11ºC/52ºF (24ºC max, 2ºC min). Rest assured, however, that just as quickly as the weather turns nasty, it can become pleasantly warm. Night-time temperatures will most likely range from –1°C to -5°C (30s and 40s ºF) depending on the weather.
