The season
What fills Akaka Falls, and when
Kolekole Stream drains one of the wettest coasts in the country, so Akaka runs year round with its heaviest water in the November through April wet season and quick surges after any Hilo-side downpour; the rain-fed label is our classification of that regime. The neighboring Kahuna Falls shares the same loop trail and the same weather.

What the agency itself says
Pleasant self-guided walk through lush tropical vegetation to scenic vista points overlooking the cascading Kahuna Falls and the free-falling 'Akaka Falls, which plunges 442 feet into a stream-eroded gorge. The 0.4-mile loop footpath requires some physical exertion.
Rain-fed falls carry the color of their watershed: Blackwater Falls runs amber with tannin from spruce and hemlock bogs upstream, and its volume tracks the last month of Appalachian weather. “Blackwater Falls (15437499241)” by Benjamin Smith from United States, CC BY 2.0
Getting there
Access, in the agency's words and ours
The 0.4 mile paved loop involves steps and some exertion and is not wheelchair accessible, per the state park. As of 2026 the park charges non-residents a $5 entrance fee plus $10 parking, card only, with Hawaii residents free; paying online before arrival is encouraged since cell service is thin.

Kolekole Stream has no USGS gauge near the falls, so the seasonal pattern above is the flow guide for Akaka Falls, and Akaka Falls State Park (Hawaii DLNR Division of State Parks) is the source for current conditions on the ground.
No; the Hamakua Coast does not really have a dry season by mainland standards. The falls simply swings between full and fuller, with the biggest curtains following winter rain events.

Yosemite Falls in May, running on snowmelt that will be gone by late summer. The National Park Service tells visitors the falls can be dry by August, which is why every falls page here starts from its watershed. “Tourists below Yosemite Falls (39832011431)” by Mike McBey, CC BY 2.0
Kauai's easiest great falls: a roadside overlook above the Wailua River valley, with the falls splitting and rejoining across its basalt lip as the rain dictates.
The double falls at the end of Maalo Road made famous by television, pouring off the South Fork Wailua and swelling into a single curtain after Kauai rain.
