Climate of Guaviare

The department of Guaviare occupies a transition zone between the Eastern Plains and the Amazon, giving it climatic characteristics of both regions. San José del Guaviare, its capital, has temperatures of 25 to 30 °C with high humidity. Colombia's most emblematic tepui —the Sierra de Chiribiquete, a World Heritage Site— rises in Guaviare with its inaccessible sandstone plateau, generating its own microclimates on its walls and summits. The Guaviare River visually separates the plains to the north from the Amazon rainforest to the south, and this transition is also reflected in the climate: more seasonal to the north, rainier to the south.
