Prior to the construction of the harbour wall in the 1920s, the beach from the Baakens River to the Shark River was largely unusable for swimming purposes. This is the reason why the first beach south of the Baakens River to gain popularity was Humewood.
Yet after the erection of the harbour wall, there was a steady accumulation of sea sand against the sea wall to the point where the accumulated sand now stretches along the whole length of the wall.

Apart from the fact that the sand had commenced accumulating against the harbour wall, note that Humewood was scarcely developed. Furthermore, the development of Summerstrand had barely commenced.
This phenomenon has occured in other locations as well. This accumulation of sand has also happened around Coolangatta on the Gold Coast in Australia.
