Deff avoid west coast at that time of year. Koh Tao should be best bet for weather. If anyone's thinking of doing a course Id say avoid the small number of sops offering openwater for under 6k Baht. They seem to cram all confined sessions into one day and with groups of 8 - you dont get much 1 to 1 attention. Also have to wonder where else they're cutting costs generally, not unheard of for there not to be o2 on the boats of these low cost operators.
By the large though, the majority of the dive centres on KT are very professional and all seem to have large numbers of assistants on most courses in the form of trainee DM's.
