How is the diving in September? We heard September is the worse time to come to Thailand for visiting and diving but the reviews here seem to contradict that.
Viz was ok, the fact it is quieter at the sites in Phi Phi islands more than makes up for this. I found it more than ok if I'm honest. Check when the marine parks are open as they close for part of the year although there is plenty of diving all year. It was perfect for me completing OWC. Viz was no worse than Great Barrier Reef off the Whitsundays.
