The best time to go to Lagos Posadas is during the summer months, from December to March, to enjoy the warmest weather and outdoor activities.
During this period, the Patagonian summer offers long daylight hours and average temperatures ranging from 15°C to 25°C, making it ideal for exploring the natural beauty of the region. This is when the hiking trails around Lake Posadas and Lake Pueyrredón are most accessible, and boat trips on the lakes are readily available.
For those interested in fishing, particularly for trout, these months are also prime season as the waters are generally calm and fish are more active. Families often find this time particularly suitable for a relaxed holiday, with opportunities for gentle walks, picnics by the lake, and enjoying the stunning mountain scenery without the chill of other seasons.
Travellers looking for a more solitary experience or keen photographers might also consider the shoulder seasons of November or April. While slightly cooler, these months offer fewer crowds and the chance to see the landscape in different light, with autumn foliage in April providing a striking backdrop.
