The best time to visit Andacollo is generally during the summer months, from December to February, when the weather is at its warmest and most stable.
During this period, you can expect pleasant temperatures, typically ranging from 20°C to 30°C, making it ideal for outdoor activities and exploring the natural beauty of the Neuquén region. The longer daylight hours also allow for more time to enjoy excursions to nearby attractions like the Huinganco Forest or the stunning Lake Nahuel Huapi, which is a short drive away. This season is particularly good for couples or families looking to make the most of the area's hiking trails and scenic drives.
If you prefer cooler weather and fewer crowds, the shoulder seasons of spring (September to November) and autumn (March to May) also offer a good experience. Temperatures are milder, usually between 10°C and 20°C, and the landscapes are often vibrant with spring blooms or autumn colours. This can be a great time for solo travellers interested in photography or those seeking a more tranquil experience before or after the peak tourist period. However, some higher-altitude roads might still be affected by snow in early spring or late autumn.
