Inca Trail to Machu Picchu|
Weather in the Andes Mountains
From June to August, winter in Peru, days are typically sunny and warm. The temperature can drop to below freezing (27°F -3°C) at night in high camps. Rain seldom falls during winter. This time of year is considered the High Season in Peru and the time most tourists visit the area both for mountain treks in the Andes and for jungle trips to Manu and Tambopata.
From January to March, the Peruvian summer months, daytime temperatures are 85°F 30°C, milder nights (typically to 45°F 8°C) and plenty of rain. Despite some rain, December is a great month for trekking, since the mountains are lush with summer flowers and you enjoy plenty of sunshine. Although this is the off-season for tourism there are good opportunities to enjoy adventures both in the mountains and in the jungle areas for travelers who understand more time might be needed in their travels to accommodate for weather concerns.
NOTE: The Inca Trail to Machu Picchu is closed during February each year.
