Ili River, month by month
Highest water: from April to June
Lowest water: from January to February and from September to October. Freezing months (average below −4 °C): from December to February. Best months to visit: from May to September.
From about 26 m³/s in the lowest month to 740 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.
