Sambre, month by month
Highest water: from December to February
Best months to visit: from May to September.
From about 62 m³/s in the lowest month to 300 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.
