Golden hour & blue hour by month
Waterfalls photograph best in soft, even light: overcast days, deep shade, or the hour after sunrise before direct sun hits the water. Bright sun on white water blows highlights and adds harsh contrast.

Milky Way & night sky
From Kahūnā Falls, the Milky Way core is visible in a dark sky from February through October. June gives the longest window (about 7.8 hours on a moonless night), and the core peaks around 41° above the southern horizon. Our light-pollution model puts the sky at about Bortle 3 (rural sky), good enough for detailed Milky Way images.

Window when the galactic core is at least 10° high during astronomical darkness on the 15th of each month. Pick nights within a few days of the new moon. Plan exact nights with the Milky Way planner.
Estimated sky darkness: 3 Bortle 3 — Rural sky. Some light domes sit on the horizon, but the Milky Way still looks complex overhead. Modeled zenith brightness ≈ 21.51 mag/arcsec².
Weather & best season
Long-term NASA satellite data for this area show January as the clearest month (about 50% average cloud cover) and March as the cloudiest (62%). August is the warmest month and February the coldest, which matters for gear, snow access and how long batteries last at night.

Photography tips for this waterfall
- Spring snowmelt and the days after heavy rain give the strongest flow; late summer flow can drop to a trickle.
- Look for a foreground: a mossy boulder, a fallen log or the creek's leading lines make a stronger frame than the falls alone.
- Keep a microfiber cloth handy — spray drifts onto the lens, especially at the plunge pool.
- Bracket shutter speeds: 1/8 s, 1/2 s and 2 s give very different water textures and you can choose later.
- Scout in daylight if you plan to shoot at night or before sunrise.
Season: Peak flow is usually in late spring; autumn adds color around the falls, and winter can bring ice formations at colder locations.
Suggested gear: Tripod, Circular polarizer, 3–6 stop ND filter, Lens cloth, Waterproof footwear. Work out exposures with the depth of field, ND filter and NPF rule calculators.
