The weather is fine all year round, with the exception of some rain showers during summer months. Koh Kood is influenced by the northeastern and southwestern monsoons.
The best time for a visit to Koh Kood is surely between beginning of November and the end of April. At this time it is relatively cool, dry and mostly sunny. Even during the monsoon season, Koh Kood is worth visiting as it doesn't rain every day and all day long.
