How does Viti Levu’s central mountain range affect rainfall across the island?

The central mountain range of Viti Levu acts as a climatic barrier that divides the island into two distinct zones. By obstructing prevailing winds, the mountains create a sharp contrast in rainfall between the two sides of the island.12

The southeastern section of the island experiences a wet climate, receiving approximately 120 inches (3,050 mm) of rain annually. In contrast, the northwestern section is significantly drier, receiving between 70 and 90 inches (1,800–2,300 mm) of rainfall per year. This orographic effect leads to notable differences in both climatic conditions and agricultural practices across the island, with the drier west supporting industries such as sugarcane cultivation.12
