We didn't go to Oahu to dive, but since we were going diving in Micronesia's Truk Lagoon, and we had to fly through Ohahu, it made sense to stop there for a few days and dive a bit while we were there. Ohahu not being a prime diving destination compared to the other islands, it catered to beginner divers more than confirmed ones. It was hard to find a dive shop that would ensure we didn't have crappy dives due to a boat full of beginners.
Our first day, we went with Hawaiian Diving Adventures, met them at 07:15, and were lucky enough to be the only divers that day (just after thanksgiving weekend). Our first dive was the sea tiger, a nice boat sunk on purpose:
Our second dive was "the pipe", minimal life, but a bit more fun with the octopus our guide found:
Two days later, I chose Reef Pirates, because they had a 3 tank dive that was more geared towards experienced divers. Sadly we did not luck out that day as they made us go there by 06:30 (getting up at 05:40), and then left 45mn late while they were sorting out whether they would allow a diver with medical conditions, join us, or not.
Once diving the Coraair plane wreck, they forced us to go back up after barely 10mn down there, even though I still had 12mn of bottom time left on my computer. I'm not impressed by such forced babysitting :(
The next dive was Angler's Reef, where our guide found another reef octopus:
Last was Koko crater, with two underwater Buddhas and lots of turtles (more than 7 different ones, one of which sadly had a piece bitten off, probably by a shark):
And that was it for diving in Oahu, not super impressive, but not terrible either. At least the water was still reasonably warm during the winter (25C or better).
