Cat Island Light — a lighthouse in Harrison County, Mississippi — is a classic subject for landscape photographers. It sits roughly 12.5 km (7.8 mi) SE of Pass Christian. It dates from 1831.
The Cat Island Light was a lighthouse located on Cat Island off the coast of Mississippi. Originally built to guide shipping through the Mississippi Sound, it was discontinued as traffic moved further south.From the Wikipedia article “Cat Island Light”, licensed under CC BY-SA 4.0.

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 Cat 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 4 (rural / suburban transition), 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: 4 Bortle 4 — Rural / suburban transition. Light domes are visible in several directions; the Milky Way is clear but lacks detail near the horizon. Modeled zenith brightness ≈ 20.85 mag/arcsec².
Weather & best season
Long-term NASA satellite data for this area show October as the clearest month (about 39% average cloud cover) and February as the cloudiest (60%). 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
- 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.
- Scout in daylight if you plan to shoot at night or before sunrise.
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 Cat Island, 4.3 km (2.7 mi) away. Low tide often reveals tide pools, wet-sand reflections and sea stacks.
