When to go 
You may have a good holiday in Sunrise Beach of Koh Lipe island all year round. Winter half of the year is a dry season, so it will be a great sunny weather.
On the other hand the summer is a rainy season, but there are no many tourists as well. Another good thing about the summer half of the year is that the wind blows from the west, so there are no waves on the eastern beaches.
