Sunset Beach, Public beach in Pinellas County, Florida

Sunset Beach is a public beach in Pinellas County along the Gulf of Mexico, where light-colored sand forms a natural edge between the water and the residential areas of Treasure Island behind it. The shoreline stretches for some distance and provides access to the waterline as well as views across the surrounding islands.

Sunset Beach lies on the Gulf side of Treasure Island, in Pinellas County. The beach was widened in 2013 when the U.S. Army Corps of Engineers placed new sand after a tropical storm had stripped material from the shore. The added sand rebuilt the profile of the beach and limited further loss to erosion.

Sunset Beach sits at the western end of Treasure Island, where the road and the sand meet Blind Pass, the channel separating the island from Treasure Island's southern neighbour. The pass is a popular spot for fishing and watching boats move between the Gulf and the Intracoastal Waterway.

Sunset Beach lies at the end of the Sunset Beach district on Treasure Island, reached by Gulf Boulevard and the Sunshine Skyway from St. Petersburg. The sand is fine and pale, and the water is shallow near the shore. Summer afternoons bring thunderstorms, so mornings are drier. The beach faces west, so the sun sets over the Gulf.

Sunset Beach sits at the mouth of Blind Pass, the channel that separates Treasure Island from the barrier island of St. Pete Beach to the south. The pass carries tidal water between the Gulf of Mexico and the Intracoastal Waterway, and its sand shoals shift with storms and currents.
