April to November on the Andaman coast side is the monsoon/wet period so a very big chance you are going to see rain & most likely plenty of it.Even if it`s not raining more than likely the beach won`t be too flash depending on what the weather has been like but you may well get good enough weather for a few days to hang around the pool.

The islands on the Gulf of Thailand side are normally a better & safer bet for good weather in July.
