The water at Aber Falls, month by month
It roars from October to February.
The fullest months: from October to February.

- 0.6 m³/sDec
From about 0.15 m³/s in the lowest month to 0.62 m³/s in the highest. Best months to go, with plenty of water and pleasant days: April and from September to November.
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.

134 kW
About 0.37 m³/s falling 37 m: the power of the water as it drops.
- enough to power about 34 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 248 m in 1.8 km. Here the river runs about 45 m below the lower rim of its valley.
