Puno Climate

The Peruvian Andes and Amazon have 2 main seasons: the rainy season and the dry season. The rainy season is from October to April and the dry season generally runs between May and September.

Temperatures range from 59º F/15º C to 71º F/22º C in summer to around 41º F/5º C to 60º F/16º C in winter. By collecting the sun’s heat during the day and releasing it at night, the lake provides a thermal effect that provides the city with a considerably warmer climate than other cities in the region.

Similar to Cuzco, rain is essentially restricted to the winter months, with intensely blue skies gracing the region during summer. However, when the sun is obstructed by beautiful fluffy white clouds, expect surprisingly crisp temperatures and remember to always keep some warm layers accessible.

In the evenings it also becomes notoriously cold, with temperatures dropping to below freezing from June through to August. In the day, the sun is intense and sunburn is common so do stock up on sunscreen if planning to visit.
