Dutch Island Light is a lighthouse in Washington County, Rhode Island. The nearest town is Jamestown, about 3.1 km (1.9 mi) away (Dutch Island Light lies W of town). Its recorded tower height is about 13 m (43 ft). It dates from 1826. It is listed on the National Register of Historic Places.
Dutch Island Light is a historic lighthouse on Dutch Island off Jamestown, Rhode Island. In 1825 the federal government acquired 6 acres (2.4 ha) at the southern end of the island, and on January 1, 1827, Dutch Island Light was established to mark the west passage of Narragansett Bay and to aid vessels entering Dutch Island Harbor. The first 30-foot (9.1 m) tower was built of stones found on the island. The government constructed a new 42-foot (13 m) brick tower in 1857 with a fog bell added in 1878.From the Wikipedia article “Dutch 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.

Local time (America/New York), including daylight saving time. Golden hour runs from about −4° to +6° solar altitude, so the morning golden hour begins during blue hour, before sunrise.
Milky Way & night sky
From Dutch Island Light, the Milky Way core is visible in a dark sky from March through September. June gives the longest window (about 4.5 hours on a moonless night), and the core peaks around 20° 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 ≈ 19.31 mag/arcsec². Aurora needs roughly Kp 6.0+ to show low on the northern horizon here.
Weather & best season
Long-term NASA satellite data for this area show August as the clearest month (about 52% average cloud cover) and January as the cloudiest (69%). August 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.
- 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.
Tides
The nearest NOAA tide prediction station is West Jamestown, Dutch Island Harbor, 1.5 km (0.9 mi) away. Low tide often reveals tide pools, wet-sand reflections and sea stacks.
