How Much Does It Rain in El Yunque?

Soul-refreshing, body-cooling, and enchanting! That's just a few ways you can describe the ambiance at El Yunque National Forest, the only tropical rainforest in the U.S. National Forest System.

Located on the east side of Puerto Rico, this forest is known to be one of the most biodiverse spots in the mainland and across the states. There, you'll find very lush trees and bushes – 240 species to be exact, endemic fauna like the beloved coquí and Puerto Rican parrot, and bountiful waterfalls, rivers, creeks, and streams.

Yes, this is the ideal place to practice your Tarzan jungle call!

While it is not a waterpark, the "rain" part in the rainforest qualification is very accurate. It rains at least four times a day in the interior of El Yunque, and this is vital to the Island's various ecosystems and its residents.

Since you're bound to get wet when you visit, it is essential to wear sturdy shoes to avoid slipping on the wet, muddy road when you venture into the mountains. Grab a raincoat or an umbrella, or simply dance under the rain as you explore one of Puerto Rico's crown jewels.

Here are some facts about the water in El Yunque

Rainfall comes in showers multiple times a day, with records showing from 0 (extremely rare) up to 9 inches of water in a single day. On average, that's about 100 Olympic-sized pools per day!
El Yunque is not only the rainiest place on the Island, but also the rainiest forest of all the National Forests, with an average of 120 inches of rainfall up to 240 inches a year. That is over 100 billion gallons of rainwater! Those billions of gallons, combined with water from the eight major rivers that originate in the forest, make up 20% of the drinkable water in Puerto Rico.
The primary public uses of the water drained from the forest are municipal and domestic water sources. There are also recreational opportunities for visitors and the surrounding communities, such as natural swimming pools and scenic waterfalls for that perfect Instagrammable shot.
There is a dwarf forest within El Yunque because the constant cloud cover and rainfall make it difficult for plants and trees to take root; the soil is so wet that they grow miniaturized versions of themselves at the highest points of the mountains.
