rainfall can exceed 10,000 mm/yr with little seasonal variation. Away from the montane influence however, rainfall averages 3,000 mm/yr along the coast falling to around 2,000 mm inland and there can be a short but sometimes severe dry season of 2 to 3 months. Humidity is always high, rarely dropping below 90 percent. Temperatures range from a maximum of 27 to 33 °C, to a minimum of 15 to 21 °C, with very minor seasonal differences.
lake lies in a steep crater with an average rim height of 60 meters above the surface of the water. Its basin is 875 mtrs in diameter and has a max depth of 14.5 meters. A single small outflow stream drains northward into the Mbu River, a tributary of the Cross. Lake Bermin enjoys the same climatic regime as Barombi Mbo. The lake is clear, with dry season underwater visibility of 4.5 meters. Its water is alkaline [pH 7.5] and soft, with a conductivity of 80 microSeimens/cm at 20oC. The ichthyofauna of Lake Bermin is intact. ALL of Lake Bermin's cichlids are biparentally custodial substratum spawners, their reduced fecundity makes them as vulnerable as their mouthbrooding counterparts in Barombi Mbo to the depredations of translocated fry predators.
