Rainfall in Tropical Rainforests

Tropical rainforests receive 50–260 inches (125–660 cm) of rain annually on average—the highest of any terrestrial biome. Some locations (e.g., Pacific slopes of Andes, Mount Waialeale, Hawaii; Cherrapunji, India) exceed 400 inches (1,000 cm). Rainfall is distributed year-round with no true dry season, though some areas have wetter/drier periods. This constant moisture drives unparalleled productivity and biodiversity.
