Roe Island Light — a lighthouse in Contra Costa County, California — is a popular subject for landscape photographers. It lies in or next to Port Chicago Naval Magazine National Memorial, so park hours, fees and rules apply. It sits roughly 7.2 km (4.5 mi) NW of Bay Point. It dates from 1891.
Roe Island Lighthouse was a lighthouse on Roe Island on the east end of Suisun Bay, California.From the Wikipedia article “Roe 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 Roe Island Light, the Milky Way core is visible in a dark sky from March through September. June gives the longest window (about 5.3 hours on a moonless night), and the core peaks around 23° 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 ≈ 19.15 mag/arcsec².
Weather & best season
Long-term NASA satellite data for this area show July as the clearest month (about 19% average cloud cover) and December as the cloudiest (57%). 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
- 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.
- Tell someone where you're going in remote areas and carry the ten essentials.
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.
Permits, drones & access
National Park Service rules. Under federal law (54 U.S.C. 100905), still photography in National Park Service areas needs a permit only when it (1) takes place where members of the public are not allowed, (2) uses models, sets or props that are not part of the location's natural or cultural resources or administrative facilities, or (3) would cause the park to incur additional administrative costs to monitor the activity. Ordinary visitor and most landscape photography needs no permit. Commercial filming rules are separate and have changed in recent years — confirm current requirements with the park before a paid shoot.
Drones: Launching, landing or operating unmanned aircraft (drones) is prohibited in National Park Service units under a 2014 Superintendent's closure (36 CFR 1.5), except where a park has issued specific written approval. Flying from outside the boundary over park land can also violate park rules and disturb wildlife.
