I dove 6 dives on Oahu back in May. THe diving was great.... not much on the coral side of things, but I dove some nice wrecks. Like stated above really nice fish there. I am from Texas and I am a requent diver of the Gulf, so I have on thing to say about hawaii water.....ITS COLD! 3mil wet suit works wonders! Have fun. If you are on Oahu, call up Oahu Scuba Divers they are great to dive with, I have a dive master all to my self.
