Ishikari River, month by month
Highest water: from April to May
Lowest water: from January to March and July. Freezing months (average below −4 °C): from January to February. Best months to visit: from June to July.
From about 90 m³/s in the lowest month to 1,300 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.
