The Peruvian Andes are dominated by the majestic mountain range, creating diverse ecoregions across distinct altitudinal tiers. The climate features two marked seasons: dry winter (April to October) with clear sunny days (up to 24°C / 75°F), chilly nights, and minimal rain; and wet summer (November to March) with frequent alpine showers and temperatures dropping near freezing (-3°C / 26°F).
