Madre de Dios is a region in southeastern Peru, bordering Brazil, Bolivia and the Peruvian regions of Puno, Cusco and Ucayali. Its capital is the city of Puerto Maldonado. The name of the region is a very common Spanish language designation for the Virgin Mary, literally meaning Mother of God.
The region is almost entirely low-lying Amazonian rainforest. The climate is warm and damp, with average temperatures around 26 °C (79 °F) [max.: 34 °C (93 °F), min.: 21 °C (70 °F)]. The rainy season is from December to March, when torrential rainfall causes rivers to swell and often burst their banks. Annual precipitation can be as much as 3 metres (9.8 ft).
