The Rapid Bay Jetty region covers the southern Fleurieu Peninsula in Gulf St Vincent, South Australia, and encompasses a varied set of sites ranging from shore-entry beginner reefs to an advanced wreck dive. The three sites in our database are Second Valley, a reef and cave site with good visibility; Myponga Beach, a shallow shore dive suitable for beginners; and the HMAS Hobart, a one-hundred-and-thirty-three-metre destroyer scuttled in two thousand and two that sits upright to thirty metres and is restricted to advanced wreck-certified divers due to strong tidal currents. Leafy Seadragon is recorded across the region alongside Giant Cuttlefish, Fiddler Ray, and Harlequin Fish. Water temperatures are cool year-round, peaking in late summer and dropping to the low-to-mid teens in winter.
Monthly water temperature across Rapid Bay Jetty's sites, from satellite sea-surface data corrected for depth. The band shows the site-to-site spread.
Temperatures peak in late summer and fall to their coolest from mid-winter through early spring, making a drysuit or thick wetsuit practical for much of the year. The HMAS Hobart demands careful tidal planning due to strong currents, while Second Valley is best dived around the turns of the tide to avoid tidal flow around the point.
