Golden hour & blue hour by month
Lighthouses work at both ends of the day: blue hour when the beacon is lit, and golden hour when white towers take on warm tones.

Milky Way & night sky
From Diamond Head Light, the Milky Way core is visible in a dark sky from February through October. June gives the longest window (about 7.7 hours on a moonless night), and the core peaks around 40° above the southern horizon. Our light-pollution model puts the sky at about Bortle 8 (city sky), so expect visible sky glow; drive away from towns for better results.

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: 8 Bortle 8 — City sky. Only bright constellations are visible; the sky glows orange or white. Modeled zenith brightness ≈ 18.09 mag/arcsec².
Weather & best season
Long-term NASA satellite data for this area show July as the clearest month (about 47% average cloud cover) and March as the cloudiest (61%). 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 lighthouse
- A telephoto from across a bay compresses the tower against cliffs or the moon.
- Many lighthouses are on private or Coast Guard property — check public access and opening hours.
- Moonrise or the Milky Way over the tower makes a classic night composition; plan with the azimuth tables.
- During blue hour, use 5–15 second exposures to capture the beam; check whether the light is still active.
- Shoot from the beach or a jetty to place the tower against open sky and sea.
- Tell someone where you're going in remote areas and carry the ten essentials.
Season: Summer brings open towers and tours; autumn and winter offer storms, fewer crowds and lower sun angles.
Suggested gear: Tripod, Telephoto lens, ND filter for smooth water, Rain cover. Work out exposures with the depth of field, ND filter and NPF rule calculators.
Tides
The nearest NOAA tide prediction station is HONOLULU, 7.7 km (4.8 mi) away. Low tide often reveals tide pools, wet-sand reflections and sea stacks.
