North of the Torrens River the coast runs north-northwest for 10 km to the protruding sandy Semaphore foreland, then slowly curves into west facing Largs Bay. This entire 16 km of beach is backed by Adelaide’s beach suburbs. It is bounded by the Torrens and North Haven breakwaters, with four jetties crossing the beach. Waves average less than 1 m at the southern Henley, and decrease even further north of Semaphore. At the same time the beach has a continuous attached bar, fronted by a trough then a second bar, and past Semaphore and into Largs Bay a third bar is present, however waves only break on the outer bars during higher wind wave conditions. Under normal low wave conditions these are all relatively safe beaches. Just be aware of the troughs between the bars if swimming out past the inner bar. read more
