The water at Yudaki Falls, month by month
It roars from July to October.
The fullest months: from July to October. Below −4 °C on average (from December to March): the falls can partly freeze.

From about 0.26 m³/s in the lowest month to 0.96 m³/s in the highest. Best months to go, with plenty of water and pleasant days: from July to October.
Estimate: the timing comes from rain, snowmelt and evaporation (NASA POWER, 1991–2020); the amounts from the river model of HydroATLAS (WaterGAP, 1971–2000). Dams upstream can change the real flow.
Yudaki Falls is a waterfall on the Lake Yunoko, in Japan. The water falls 75 m over a front 25 m wide. It lies within Nikkō National Park.

447 kW
About 0.61 m³/s falling 75 m: the power of the water as it drops.
- enough to power about 112 homes, if it were all turned into electricity
Power of falling water = density × gravity × flow × height. Average flow and height as shown above; an estimate.

The line follows the river as mapped in OpenStreetMap; heights from the 30 m Copernicus model, which smooths narrow drops — the published height of the falls is the one above.
Around the falls the river drops 82 m in 1.9 km. Here the river runs about 74 m below the lower rim of its valley.
