In terms of surf, I have yet to see bad conditions at the breakwater. That's one of the nice things about it. Viz is another matter, but once you get below the thermocline at about 30 feet it opens up a little, at least that's how it's been the last 3 or 4 times we went there. For first time I'd suggest staying by the rocks of the breakwater itself, partly for ease of navigation and partly because that's where the best critters are. We like to enter about 20-30 feet away from the rocks, just in case a few rogue waves come along and try to bash us onto the rocks, then surface swim out to about where the wrought-iron gate can be seen, drop there and swim over to the rocks, then just head to the left and wander up and down the rocks, out to about 40 or 50 feet depending on how our air is and what we bloomin' well feel like doing
We don't stay down at the bottom, we wander up and down the rocks as we move further out, varying our depth as much as 20 feet if one of us sees something interesting here or there. Once we turn around, we often like to get down by the sandy bottom and watch for the fields of tube-dwelling anemones, because that's where we often find the giant nudibranchs (
Dendronotus iris) and watch them sneak up on the anemones. Further in, around 10-15 feet, there's a nice field of sand dollars out there as well, but as often as not we drift back over to the rocks once we're out of the anemones. I should mention that we're "macro" people; we like to find the little stuff that most folks tend to overlook. In particular, we're nudibranch freaks.
Bear in mind that I'm new to this area, so I could be talking through my hat. (okay, my hood.) But that's how we did it when we first got here, and it seemed to work. For what it's worth.
