Bia River, month by month
Highest water: from June to July
Lowest water: from January to March. Best months to visit: from December to January and August.
From about 55 m³/s in the lowest month to 230 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.
