What is the average yearly rainfall in a rain forest?

In a typical year, a tropical rain forest gets an average of 50 to 260 inches of rain. This helps the climate stay very hot and humid.

Rainfall in a rain forest usually exceeds 100 inches per year, but there is a brief period of less precipitation. In areas where monsoons occur, there is actually a very dry season. Temperatures in a rain forest stay between 68 and 93 degrees F. The incredible amounts of rain keep the humidity level between 77 and 88 percent all year long. Although scientists believe that at least half of all the world's plant and animal species live in here, rain forests only cover about six percent of the planet's surface.
