Adda, month by month
Highest water: from November to December
Best months to visit: from May to September.
From about 79 m³/s in the lowest month to 480 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.
