Yana, month by month
Highest water: from July to September
Lowest water: from January to April. Freezing months (average below −4 °C): from October to April. Melting snow makes up much of its water. Best months to visit: July.
From about 71 m³/s in the lowest month to 4,200 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.
