I've only been diving here at the Turkey Head breakwater twice before over 15 years ago. Back then, it was covered by kelp in the Summer and, pretty bare and silty in the Winter. I don't really remember much about it except for the descriptions on my website, so I came back to refresh my memory on Feb. 24, 2024.
I swam down along the base of the boulder breakwater out towards its tip. The bottom here was only about 20' deep (my maximum depth was 25'). Visibility was a stirred-up 8'. Just like the last time I dove here, the rocks were mostly bare except for grey-brown silt and red-coloured seaweed. Most of the marine life was a variety of nudibranchs.
Out near the tip of the breakwater, the current was almost too strong to swim against. During the previous times I dove here, the current was very strong as well so this time I tried to time the dive according to the Baynes Channel current correction and the Discovery Island current table, but the current was still very strong and flowing in towards the marina. I didn't want to get caught in it since it would be a long swim or an awkward climb to get back from inside the marina, so I only had a brief look around the tip of the breakwater. The eelgrass on the sand was lying flat in the flow. There was also some stalked kelp out there. Despite the current, the boulders were still bare and grey looking. There were a few patches of more colourful invertebrates like tunicates and sponges under the overhanging hollows of some boulders.
