BEST TIME TO TRAVEL THAILAND
The winter months bring the coolest days, but also lots of tourists. Who doesn't mind to give up a bit of sunshine, can choose to travel in the more quite rain season from June till October or melt on the beaches because of the heat in April and May. The East coast (Koh Samui) is less disturbed by the moesson than the West coast (Phuket).
The overall best time to travel is November till Februari.
