Weather in the region is extremely variable and you should pack for a variety of conditions. In addition, our trek passes through ten bio-zones ranging from high altitude alpine conditions to high jungle. During a sunny day, you can expect temperatures of about 18–25°C (65–77°F), however, on the second day the weather is very unpredictable and temperatures can drop to 6°C (42°F) during the day at the pass (but you won’t spend a lot of time up there).
The Machu Picchu area has a humid climate and tends to be warmer since it is located at a lower altitude and near the Amazon Jungle. The average temperatures at Machu Picchu are between 23°C to 25°C (73°F and 77°F), with the minimum temperature around 18°C (64°F). The Cusco area has only 2 well-defined seasons: the wet season and the dry season. The wet season starts in November and ends in March. During this period, it rains almost every day for three or four hours, but also there are several sunny days. The dry season begins around March and lasts until October. June and July are the coldest months. Paradoxically at noon, the temperatures can reach 23 °C (77°F), the annual highest temperature.
