Luan River, month by month
Highest water: August
Lowest water: from December to March. Freezing months (average below −4 °C): from December to February. Best months to visit: from May to June and September.
From about 14 m³/s in the lowest month to 400 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.
