Grebeni (Reef & Caverns)

Grebeni sits on exposed offshore islets, but the dived wall is on the south/seaward flank facing the open Adriatic, while the Lapad/Babin Kuk peninsula and Dubrovnik coast lie close to the north and northeast (nearest headland ~700 m at bearing 37deg), shadowing the N-NE-ENE sector — Bura (NE) is also offshore and blocked here. The main crag immediately to the north-northwest and the western tip of the islet chain (~225-280 m at 285-292deg) block the N-NW-WNW arc. The eastern crags of the chain and Mala Afrika reef sit at bearings 78-96deg and partially shadow the E-ESE. The open window is S-SSW-SW and the SE: southerly swell and especially the Jugo/Scirocco from the SE — which has the longest fetch along the Adriatic's NW-SE axis and is open water off this west-end pin — wrap straight onto the south wall and are what raise surface waves and force cancellations.
