Horn Island Light is a lighthouse in Jackson County, Mississippi. The nearest town is Pascagoula, about 17.2 km (10.7 mi) away (Horn Island Light lies SSE of town). It dates from 1874.
The Horn Island Light (in later years also known as the Petit Bois Light) was a lighthouse in Mississippi originally located at the eastern end of Horn Island. Moved and rebuilt several times, it was deactivated and abandoned in 1961.From the Wikipedia article “Horn Island Light”, licensed under CC BY-SA 4.0.

Milky Way & night sky
From Horn Island Light, the Milky Way core is visible in a dark sky from February through October. June gives the longest window (about 6.7 hours on a moonless night), and the core peaks around 31° 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 ≈ 21.39 mag/arcsec².
Weather & best season
Long-term NASA satellite data for this area show October as the clearest month (about 40% average cloud cover) and December as the cloudiest (61%). July is the warmest month and January the coldest, which matters for gear, snow access and how long batteries last at night.

Photography tips for this lighthouse
- Stormy weather and crashing surf add drama; keep a safe distance from waves on rocks and piers.
- 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.
- Shoot RAW to keep the most latitude for high-contrast sunrise and sunset scenes.
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 Petit Bois Island, Mississippi Sound, 4.8 km (3.0 mi) away. Low tide often reveals tide pools, wet-sand reflections and sea stacks.
