Milky Way & night sky
From Point Arena Light, the Milky Way core is visible in a dark sky from March through September. June gives the longest window (about 5.0 hours on a moonless night), and the core peaks around 22° above the southern horizon. Our light-pollution model puts the sky at about Bortle 2 (typical truly dark site), which is excellent for astrophotography.

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: 2 Bortle 2 — Typical truly dark site. The summer Milky Way shows rich structure; clouds look like black holes in the stars. Modeled zenith brightness ≈ 21.71 mag/arcsec².
Weather & best season
Long-term NASA satellite data for this area show June as the clearest month (about 45% average cloud cover) and December as the cloudiest (63%). 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
- 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.
- Check road and trail conditions with the managing agency before you go.
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.
