Located in Monroe County, Florida, Sand Key Light is a lighthouse. It sits roughly 14.2 km (8.8 mi) SW of Key West. It dates from 1827. It is listed on the National Register of Historic Places.
Sand Key Light is a lighthouse 6 nautical miles (11 km; 6.9 mi) southwest of Key West, Florida, between Sand Key Channel and Rock Key Channel, two of the channels into Key West, on a reef intermittently covered by sand. At times the key has been substantial enough to have trees, and in 1900 nine to twelve thousand terns nested on the island. At other times the island has been washed away completely. The light marks the southernmost point of the Hawk Channel passage along the Florida Keys.From the Wikipedia article “Sand Key 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 Sand Key Light, the Milky Way core is visible in a dark sky from February through October. June gives the longest window (about 7.3 hours on a moonless night), and the core peaks around 37° 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 ≈ 21.56 mag/arcsec².
Weather & best season
Long-term NASA satellite data for this area show April as the clearest month (about 37% average cloud cover) and September as the cloudiest (62%). 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
- 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 Sand Key Lighthouse, Sand Key Channel, 1.2 km (0.7 mi) away. Low tide often reveals tide pools, wet-sand reflections and sea stacks.
