El Yunque National Forest, located in Puerto Rico, experiences a tropical rainforest climate characterized by high humidity, frequent rainfall, and relatively stable temperatures year-round. Rainfall averages over 100 inches annually and can occur at any time, though it’s more common in the afternoons. Temperatures typically range from the mid-70s to the mid-80s Fahrenheit (low to mid-20s Celsius), with slightly cooler conditions at higher elevations.
Understanding the climatic conditions of this unique environment is crucial for visitors planning hikes and other outdoor activities. Preparedness for rain and awareness of potential flash floods, particularly during periods of heavy rainfall, are essential for safety and enjoyment. This consistent moisture nurtures the forest’s rich biodiversity, supporting a wide array of plant and animal life found nowhere else on earth. Historically, this predictable climate has shaped the development of the forest and the cultural practices of the people who have lived near it.
