Climate Characteristics of El Chaltén

General Overview

El Chaltén features a cool temperate climate. The weather here is considered one of the most unpredictable and wild in the world. Exposed to powerful westerly winds from the Pacific and the Southern Patagonian Ice Field, the town experiences extreme shifts within minutes.

Trekking Season and Summer (December to February)

Summer is the most popular season but far from warm. Daytime temperatures range between 14°C and 18°C (57-64°F), dropping to 5°C (41°F) at night. Wind is the dominant element: Gusts exceeding 100 km/h are common in summer and can make trekking challenging. Clear sunny days can turn into rain or snowstorms in no time.

Winter Season (June to August)

Winter in El Chaltén is very cold, quiet, and snowy. Daytime temperatures range from 1°C to 4°C (34-39°F), while nighttime lows are consistently below 0°C (32°F). Most trails close or become hazardous due to snow and ice accumulation. Daylight hours are very short, and many local businesses close during this period.

Transition Seasons (March-May and September-November)

Autumn (April-May) is considered by many the most beautiful time, as winds calm and vegetation turns deep red and orange. Spring (October-November) features snowmelt and lengthening days, but it is also when the strongest winds begin to blow.
