Golden hour & blue hour by month
Dunes need low sun: ripples and ridgelines only appear when side-light casts shadows, so shoot within an hour of sunrise or sunset.

Milky Way & night sky
From Sturgeon Bay Ship Canal Nature Preserve Dune and Swale Complex (Major), the Milky Way core is visible in a dark sky from April through September. June gives the longest window (about 3.3 hours on a moonless night), and the core peaks around 16° 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 ≈ 21.16 mag/arcsec². Aurora needs roughly Kp 4.5+ 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 59% average cloud cover) and May as the cloudiest (74%). 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 sand dunes
- Protect gear from blowing sand; avoid changing lenses in the wind.
- Sand surfaces get extremely hot in summer afternoons.
- Walk along ridges rather than across faces to avoid leaving footprints in your future compositions.
- A telephoto isolates S-curves and layered ridges.
- Bring a spare battery — cold weather and long exposures drain them fast.
Season: Spring and autumn for comfortable temperatures; full moon nights give soft light on the sand.
Suggested gear: Telephoto lens, Lens blower, Sun protection, Water. Work out exposures with the depth of field, ND filter and NPF rule calculators.
