hi Island_Sands
Welcome to Dubai.... been diving here for 3 years now.... been to just about every dive location there is.
UAE is split to 2 main coast lines, the west coast and the east coast.
The west coast is basically all SAND.... so as you can imagine vis is terrible and not much marine life. All dive sites are wrecks! deapth is generally 7-23m
The east coast is a totally different story, Its all mountains that drop into the sea, The east coats has the gulf of oman, that is an extension of the indian ocean. there are lovely islands and dive sites to visit.
If you really want the best divesites in the entire region, then you will have to go up north, an area called Musandam. They compare the mountains there to those of newzeland. the waters are deap and rich.
you can get some info from
www.musandamdiving.com
The only draw back is that this area is well known for its currents, they tend to reach up to 7-10 kts at times.
I personally do all my diving up there, you get huge pallagic fish siwimming by the drop offs (drops to 60-80m) GT's up to 40kg, King Fish up to 1.5m length, Sailfish, Tuna, ect .... This is area is really wild and unspoiled!
Happy diving
