Beaches are typically steeper in summer. wave fronts approach it aligned parallel to the coast, swash aligned beaches often exhibit well-defined berms, aligned at an angle to the prevailing wind direction, wave fronts approach the coast at an angle, meaning there is transport by longshore drift, may exhibit some sorting of sediment, with smaller, more rounded sediment at the furthest end, this is because smaller particles are transported by even low energy waves and are carried greater distances up the beach by each swash, more frequent movement leads to greater rounding by attrition. They can extend from a few metres to several kilometres.

In the wind shadow of an island, there is little wave action, so the sediment moved by longshore transport gets deposited, eventually linking the island to the mainland (Steven Earle, "Physical Geology"). A tombolo is formed when a spit connects the mainland coast to an island. These conditions dictate that sand accumulated on the quieter, southern side of the islands and extended in that same direction. It is a very young spit formed by processes of sedimentation around 11001200 AD.
