These are a transverse dune system with well-preserved parallel dune ridges with the highest at 14 metres. The foredune has been heavily scarped and is 2 to 3 metres above the beach. The hind dunes are separated by broad swales (or interdune depressions). Landforms here include foredune, hind dunes, swales, crests, and landward and seaward slopes.
Beach Type: Intermediate to dissipative
The coast is low to medium energy. Multiple ridges have developed as a result of shoreline progradation being dependent on an offshore sand supply reaching the beach. This building has stopped and the beach is stable to slightly erosional. Ongoing sea level rise and land subsidence in Adelaide contribute to the erosion.
Dune slopes vary from 6 to 12 degrees.
Soils are predominantly fine siliceous (quartz) sand with minor carbonate (shell) content (approx. 10%). No pedogenic development and only shallow organic staining in rear dunes. (Erodable without vegetation cover).
Cool temperate, Mediterranean, winter rainfall, warm to hot summers and cool winters.
The annual temperature maximum is 22.0 C and minimum is 12.1 C. Temperature maximum is 44 C and minimum is -0.4 C. Days over 30 C is 52.2 and over 35 C is 17.6. Average annual rainfall is 533 mm with 120 rainy days that is 32% of the year. Wind is generally on-shore which is the prevailing south-westerly.
