Supawna Meadows National Wildlife Refuge is a national wildlife refuge in Salem County, New Jersey. The nearest town is Pennsville, about 3.2 km (2.0 mi) away (Supawna Meadows National Wildlife Refuge lies SSW of town).
The Supawna Meadows National Wildlife Refuge is a component of the Delaware River estuary in Salem County, New Jersey, it is just north of the Salem River and south of Pennsville. The Delaware Bay and estuary are wetlands of international importance and an international shorebird reserve. The refuge currently owns approximately 3,000 acres (12 km2) within the 4,600-acre (19 km2) approved boundary. The brackish water tidal marshes and coastal forests that make up nearly 80 percent of the refuge provide waterfowl with a feeding and resting area, particularly during the fall and spring migrations. American black ducks, mallards and northern pintails are common winter visitors. Sandpipers and other shorebirds use the refuge marshes as a feeding area during the summer as well as during the spring and fall migrations.From the Wikipedia article “Supawna Meadows National Wildlife Refuge”, licensed under CC BY-SA 4.0.

Milky Way & night sky
From Supawna Meadows National Wildlife Refuge, the Milky Way core is visible in a dark sky from March through September. June gives the longest window (about 4.8 hours on a moonless night), and the core peaks around 21° above the southern horizon. Our light-pollution model puts the sky at about Bortle 6 (bright suburban 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: 6 Bortle 6 — Bright suburban sky. The Milky Way is only visible near the zenith; the sky glows grey-orange in photos. Modeled zenith brightness ≈ 19.23 mag/arcsec². Aurora needs roughly Kp 7.0+ to show low on the northern horizon here.
Weather & best season
Long-term NASA satellite data for this area show September as the clearest month (about 50% average cloud cover) and December as the cloudiest (63%). 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 national wildlife refuge
- A 400–600 mm lens (or a crop body) is the usual tool for birds.
- Fast shutter speeds (1/2000 s+) freeze wingbeats; raise ISO rather than lose the shot.
- Migration peaks bring the largest concentrations — see the birding calendar for this state.
- Use auto-loop roads as mobile blinds; animals often tolerate vehicles more than people on foot.
- Check road and trail conditions with the managing agency before you go.
Season: Spring and autumn migration are the highlights; winter brings waterfowl to many southern refuges.
Suggested gear: Telephoto lens (400 mm+), Bean bag for car window, Binoculars. Work out exposures with the depth of field, ND filter and NPF rule calculators.
Permits, drones & access
Drones: Launching or landing drones on National Wildlife Refuge lands generally requires a special use permit from the refuge manager, and wildlife disturbance rules apply everywhere.
