Where Are Warm Rainforests Located? Climate and Biodiversity

Warm (tropical) rainforests encircle the Earth near the equator, between the Tropics of Cancer and Capricorn. Key regions include the Amazon Basin, Congo Basin, Southeast Asia (Borneo, Sumatra, New Guinea), and Central America.

Climate is consistently warm (25–28°C / 77–82°F) and humid, with annual rainfall of 1,500–4,000 mm (59–157 inches). Soils are often nutrient-poor but rich in organic matter due to rapid decomposition. These forests harbor over half the world's terrestrial species—epiphytes, lianas, countless insects, birds, mammals, and amphibians—in complex, multi-layered ecosystems.
