i was in thailand july/aug last year and the east was pure paradise. Ko tao and the islands below were more than perfect, it was sun sun sun all the way and in 3 weeks had no rain (or so little i cant remember) but then moving cross to the west was the complete oposite, it was pretty miserable to be honest, there were dry days but these were all overcast, the tan i had i then lost haha. but i still had fun dont get me wrong!....due to the mess krabi and phi phi ect are now in my advice would be to just stick to the east islands. Ko toa i am now in love its like a mini sufer town, with wicked little chill out bars falling out onto the beach where you can watch the sun set everynight....the best place to do your PADi dive course....have i sold it to you yet?!!!
have a wicked time,
