Wadi Bana, month by month
Highest water: from August to September
Lowest water: from December to March. Best months to visit: from January to April and October.
From about 0.1 m³/s in the lowest month to 37 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.
