Sungai Belait, month by month
Highest water: from November to January
Best months to visit: from December to March and October.
From about 100 m³/s in the lowest month to 220 m³/s in the highest. An estimate: the monthly flow is modelled from the lowest and highest months of WaterGAP (RiverATLAS, 1971–2000) and the rain and snow along the river (WorldClim). Dams change the real rhythm. The chip is the average air temperature; below it, the month's rain.
