When to go? Seasons, climate, festivities
October to MarchThe summer time from October to March is the best time to visit Patagonia. December to February are the "hottest" months but the shoulder months of October and March tend to have less windy conditions. The season for Aconcagua runs from mid-November to the end of February with the main climbing season from mid-December to the end of January. We do not operate any treks in the Mendoza region beyond these months, as it is incredibly cold and windy with very limited opportunity to succeed.
April to NovemberThe best time to visit North west Argentina is from mid-April to the end of November, thus avoiding the humid heat and tropical summer rains.
