Climate in Peru varies significantly across its diverse regions, influencing travel plans and experiences. Machu Picchu, nestled in the Andes, has a subtropical highland climate. The best time to visit is during the dry season, from May to September, when rainfall is minimal, and hiking conditions are optimal. This period sees clear skies and pleasant temperatures, typically ranging from 15°C to 20°C (59°F to 68°F) during the day.
However, nights can be chilly, dropping to around 5°C (41°F), so it's advisable to bring layers. The rainy season lasts from November to April, with January and February being the wettest months. During this time, trails may be slippery and visibility can be poor. Tourists should expect heavy rainfall and should plan their visits accordingly.
In Cusco and the Sacred Valley, the climate is also characterized by two distinct seasons: dry and wet. Cusco experiences cooler temperatures, especially at night, so warm clothing is recommended.
Travelers should also consider altitude when packing. Machu Picchu sits at 2,430 meters (7,970 feet) above sea level, which can affect some visitors. Staying hydrated and taking it easy on the first day can help acclimatization.
Although the dry season is popular, visiting during the shoulder months of April and October can provide a more tranquil experience with fewer tourists. Regardless of the season, it's essential to check the weather forecast before your trip and pack accordingly. A light rain jacket is always a good idea, even in the dry season.
Lastly, be prepared for microclimates in the region. Walking from the base to the ruins can result in varying temperatures, so dress in layers for comfort.
