Coco River, month by month
Highest water: from July to October
Lowest water: from February to May. Best months to visit: from February to April.
From about 190 m³/s in the lowest month to 1,200 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.
