Milky Way & night sky
From Richardson Rock Lighthouse (historical), the Milky Way core is visible in a dark sky from February through October. June gives the longest window (about 6.0 hours on a moonless night), and the core peaks around 27° 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 ≈ 21.63 mag/arcsec².
Weather & best season
Long-term NASA satellite data for this area show October as the clearest month (about 45% average cloud cover) and July as the cloudiest (60%). 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
- 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.
- 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.
- 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 Cuyler Harbor, San Miguel Island, 16.0 km (9.9 mi) away. Low tide often reveals tide pools, wet-sand reflections and sea stacks.
