Aruwimi River, month by month
Highest water: from September to November
Best months to visit: from December to February.
From about 510 m³/s in the lowest month to 2,900 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.
