Hi Opaque
I dived the Similans in January.
The overwhelming majority of the divers had less experience than myself (AOW - 70 dives). A lot of the customers decided to do their AOW onboard the vessel, and at least one customer had come directly from Koh Tao having just completed his OW and had 6 dives to his name. The crew of the boat did a great job, defining the dive groups abilities and matching them with the guides. The guides ranged from DM to Instructors. Everyone had a great time and safety was the number one priority on the vessel I was on. Therefore it can be done.
It really depends on your timing. If coming at a time of year with strong currents (full and new moon), the currents will be strong and I would advise you not to do that.
Totally agree! TBH I was a little underprepared for some of the current I dived in. It was real learning experience for me, as I previously had very little experience diving in fairly strong current. Opaque I am not sure how much current you and your girlfriend have been exposed to in your career but the sites you mention can be exposed to currents that can be quite stressful for some. It was at times, an eye opening experience for myself. YMMV.
Similans are more relaxed than the other sites you mention, and very much worth diving,
Agreed. If you decide to skip the Similans, in favour of the sites you mentioned I think you will be missing out on some great sites, whilst also losing out on the experience you would gain, before getting to Richelieu Rock.
the stories you heard about coral bleaching are over the top. You won't notice anything ontowards there.
I am sorry, but I can't agree with this. I guess it depends on which specific sites that you dive. Some of the sites that I dived the coral bleaching was obvious, unless you dive with your eyes closed.
Opaque, my own experience from what I saw on the liveaboard I was on, was yes it can be done. My advice would be there are a few months between now and November, get as much diving experience as you can from now until then. Don't skip the Similans in favour of the "big 3". There is still plenty to see at the Similan Islands and I think it would be beneficial to ease you into the local conditions before diving your favoured sites.
