Located in Plymouth County, Massachusetts, The Graves Light is a lighthouse. It lies in or next to Boston Harbor Islands National Recreation Area, so park hours, fees and rules apply. The nearest town is Hull, about 7.7 km (4.8 mi) away (The Graves Light lies NNE of town). Its recorded tower height is about 34 m (112 ft). It dates from 1903. It is listed on the National Register of Historic Places.
The Graves Light is a lighthouse located on The Graves, the outermost island of the Boston Harbor Islands National Recreation Area, and 9 miles (14 km) offshore of downtown Boston, Massachusetts, USA. At 113 feet (34 m), it is the tallest lighthouse in the approaches to the Port of Boston, and is an important navigation aid for traffic to and from the port. It was built at the same time that the North Channel into Boston Harbor was dredged to become the principal entrance for large vessels. The Graves are the outermost rocks near the outer end of the North Channel. It was added to the National Register of Historic Places as Graves Light Station on September 28, 1987, reference number 87002041.From the Wikipedia article “The Graves 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 The Graves Light, the Milky Way core is visible in a dark sky from March through September. June gives the longest window (about 4.2 hours on a moonless night), and the core peaks around 19° above the southern horizon. Our light-pollution model puts the sky at about Bortle 7 (suburban / urban transition), 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: 7 Bortle 7 — Suburban / urban transition. The whole sky has a grey-white glow; the Milky Way is invisible to the eye. Modeled zenith brightness ≈ 18.68 mag/arcsec². Aurora needs roughly Kp 5.5+ 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 48% average cloud cover) and January as the cloudiest (70%). 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
- 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.
- 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.
- 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.
Tides
The nearest NOAA tide prediction station is Boston Light, 4.5 km (2.8 mi) away. Low tide often reveals tide pools, wet-sand reflections and sea stacks.
