Re: Southern Thailand Let's put it this way. Monsoons are the major factor in weather conditions. They always head in from South West over the Andaman Sea. And when they are gone, the Similans are open -- normally from beginning of November till end of May. However, the best time to dive there is from Februay to April.
By the way, the Similans is too far away from shore to do a day trip. Yes, there are dive operators offering day trips. Just that you would end up spending too long time in the speed boat and getting yourself exhausted.
I would recommend to sign up for a liveaboard trip. There are tons of dive operators offering such a trip to the Similans, Koh Ta Chai, Koh Bon, and Richelieu Rock. |
