LOS GLACIARES NATIONAL PARK
The climate in Los Glaciares National Park is mild, rainy, with no defined dry season but less rain in the summer.
Rain increases toward the west, showing an important difference, from 500 mm in the eastern area of the Park, to 900 mm in the cordillera (however, there have been annual registers over 2000 mm in some western sectors)
Rainfalls are distributed almost homogeneously throughout the year, reaching their peak toward the end of Autumn (April- May). During the winter precipitation is mainly snowy, but never enough to form snow accumulation.
Winds are predominantly west and southwest. During the summer they are more frequent and intense.
The average annual temperature is 7.5ēC, with an average of 0.6ēC in July (winter) and 13.4ēC in January (summer).
This information corresponds to the lower sectors, since there are no climatic registers from the top of the mountains or the higher areas within the Park or its surrounding.
Considering the theoretical decrease of 0.5ēC per 100 m in altitude, it could be estimated that the average temperature for the higher mountain sectors is in general below 2ēC and below -3ēC in the highest peaks.
Cold, windy in spring, less wind in autumn. Rainy between March and May.
