Ko Samui: When to Go

Weather

The best time to visit the Samui group of islands is during the hot, dry season from February to late June. From July to October, during the southwest monsoon, it can rain intermittently, and from October to January, during the northeast monsoon, there are sometimes strong winds. However, many travellers have reported sunny weather (and fewer crowds) in September and October. November tends to get some of the rain that also affects the east coast of Malaysia at this time.
