Ipuu Falls — a waterfall in Hawaii County, Hawaii at about 457 m (1,499 ft) above sea level — is a lesser-known subject for landscape photographers. The nearest town is Waimea, about 12.1 km (7.5 mi) away (Ipuu Falls lies NE of town).
Sunrise & sunset directions
At Ipuu Falls the sunrise point swings a long way through the year: about 65° (ENE) at the June solstice and 115° (ESE) in late December. Sunset moves from 295° (WNW) in June to 245° (WSW) in December, and the midday sun climbs to 87° in summer but only 46° in winter.

Azimuth is measured clockwise from true north (90° = east, 270° = west). Computed for 2026; values change by less than a degree from year to year.
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.

Local time (Pacific/Honolulu), including daylight saving time. Golden hour runs from about −4° to +6° solar altitude, so the morning golden hour begins during blue hour, before sunrise.
Milky Way & night sky
From Ipuu 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 2 (typical truly dark site), which is excellent for astrophotography.

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: 2 Bortle 2 — Typical truly dark site. The summer Milky Way shows rich structure; clouds look like black holes in the stars. Modeled zenith brightness ≈ 21.72 mag/arcsec².
Weather & best season
Long-term NASA satellite data for this area show January as the clearest month (about 57% average cloud cover) and March as the cloudiest (70%). September 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
- Bracket shutter speeds: 1/8 s, 1/2 s and 2 s give very different water textures and you can choose later.
- A 3-stop ND filter lets you use slow shutter speeds even when the light is bright.
- Shoot a vertical and a horizontal frame; tall falls often work better in portrait orientation.
- Use 1/4 to 1 second for a silky look; 1/500 s or faster freezes individual drops.
- A circular polarizer cuts glare on wet rocks and leaves and deepens greens — rotate it while watching the rocks, not the sky.
- Bring a spare battery — cold weather and long exposures drain them fast.
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.
