I visited this site twice in a week. As you enter the water the surf can be a little rough on some days. Come back on a calm day. We saw the normal critters, plus some squid which were very tolerant of us staying close to them. The piers in the water attract schools of fish. Follow the central piers out and then go north or south, it doesn't really matter. There seem to be some confusion on this site, before I left. It is most definitely open to divers. The entire week I was there, not a ship on the pier once, and lots of divers parked and out at the site. I would either go early or late - and avoid the crowd. I think it would make a good night dive as long as it was a calm day.
