Fire Island Inlet, Coastal inlet in Suffolk County, United States
Fire Island Inlet is a natural water passage in Suffolk County, New York, connecting the Great South Bay to the Atlantic Ocean along the southern shore of Long Island. The opening allows tidal water to move in and out, shaping the surrounding barrier beaches and wetlands on both sides of the channel.
A lighthouse was built at the inlet entrance in 1825 to help ships navigate the passage safely, reflecting how important this channel was for maritime traffic at the time. Over the following decades, shifting sands gradually moved the inlet eastward, altering the surrounding coastline in ways that required ongoing attention from local communities.
Birdwatchers regularly gather near the inlet to watch migratory birds that stop here during their seasonal journeys along the Atlantic coast. The spot is well known among locals and visitors who enjoy watching wildlife in an open coastal setting.
The inlet is accessible by boat and is popular for fishing, but water conditions can shift quickly depending on the tide and wind. Visitors on the water should stay aware of currents near the channel opening, as they can be stronger than they appear from the shore.
A man-made structure called the Sore Thumb sits at the northwestern end of the inlet and was built specifically to slow the erosion of the nearby beach. It stands out visually from the water and offers a clear example of how actively people work to manage the shape of this coastline.
