The entire Mananara Nord National Park consists of 23,000ha terrestrial park and 1,000ha marine park. The altitude reaches from 0m to 569m. The park is subject to a humid tropical climate. The average temperature is 25.2°C and the humidity is constantly high. It rains most of the year and can reach up to 2,900mm per year. There is a warm and rainy season from September to March and a cooler season from April to September. Mananara is often a passage area for tropical cyclones.
The Precambrian basement of Mananara, dating back 2,750 million years, belongs to the Antongilian system. Following geological metamorphisms that led to this substrate of rocks composed of amphibolites, micaschists, greenschist and schist, granitic intrusions of about 770 million years ago appeared which, together with Neocene alteration and erosion, are responsible for the orthogonal shape of the region's relief with narrowly linear valleys, rock walls, cascades and waterfalls, falling rocky shores and the hydrographic network following the lines of the landscape and valleys.
