From about 0.28 m³/s in the lowest month to 1.5 m³/s in the highest. Best months to go, with plenty of water and pleasant days: from May to June and from September 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.

Wet years and dry years
Rain of each month as a share of the 1991–2020 average. A wet season above 100 % usually means a fuller waterfall.
