The water at Öxarárfoss, month by month

From about 0.62 m³/s in the lowest month to 2.2 m³/s in the highest. Best months to go, with plenty of water and pleasant days: from May to June and September.
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.

208 kW
About 1.1 m³/s falling 20 m: the power of the water as it drops.
- enough to power about 52 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 28 m in 2.4 km.
