Machu Picchu has a subtropical highland type of climate (Köppen climate classification Cwb) with wet and humid summers and dry and frosty winters. Machu Picchu is an old citadel of the historical Inca Empire, which lies in Southern Peru's Cusco Region, in the Eastern Cordillera mountain ridge, above the Sacred Valley. The high altitude of the Andes Mountains and the proximity to the equator are the main factors that influence the climate of the region.

Machu Picchu, the most visited city in Peru, has an elevation of 2430 meters above sea level and lies in the southern hemisphere. The topography is mountainous, with terraced hillsides to help grow crops, and for protection against soil erosion and avalanches.

The daily high temperatures are remarkably consistent throughout the year in Machu Picchu. The wet season is from October to March, while the dry season lasts from April to September. Summers are rainy and humid, while winters are relatively dry and cold. Frost is frequent during winter nights, while mist arising from the river in the mornings is a regular feature of the climate throughout the year.

The worst time to visit Machu Picchu is from December to March during the summer, which is a part of the wet season.

Mudslides, landslides, and floods are frequent, which may lead to instances like January 2010 when Machu Picchu faced temporary closure due to the trapping of tourists and civilians on a large scale.

Machu Picchu is prone to seismic activity due to the presence of two fault lines in the region. Heavy rainfall is the leading cause of flooding, mudslides, landslides, and soil erosion. Terraces reduce the incidence of soil and water running down the mountain by the addition of layered stones, sand, dirt, and topsoil. Most of the structures are built using an architecture that reduces the threat of natural hazards occurring in the region.
