About Kauwehu Falls
Tucked into the Hilo Watershed Forest Reserve, Kauwehu Falls is a quietly beautiful, lesser-known cascade framed by lush tropical vegetation. The falls lie within a Special Conservation Area (SCA) managed by SDNR, so visitors will find a more natural, conservation-focused setting rather than developed visitor facilities. This makes Kauwehu an appealing option for hikers seeking solitude and a peaceful Hawaiian rainforest experience. The approach rewards those willing to explore a remote corner of the island with serene scenery and the hush of the forest. Because the site is managed as part of the reserve by SDNR, visitors should be respectful of the protected landscape and follow any posted guidance to help preserve the area for others.
The Setting
Kauwehu Falls sits at 1,243 feet within Hilo Watershed Forest Reserve, fed by the Wailuku River, in the foothills of Hawaii.

How we calculate this
This is a transparent outlook, not a precise forecast. We take the waterfall's current flow strength (how it ranks against its historical normal for today, from the nearest USGS stream gauge), carry that ranking forward along the gauge's seasonal curve, and nudge it for forecast rain. Confidence is highest for the next day or two and falls further out. Always check official conditions and your own judgment before visiting — high flows can be dangerous.
