During these months you'll have beautiful hot days (25°C - 40°C) with very little cloud and low humidity. Koh Rong's Climate Over Time In general, Koh Rong’s weather patterns tend to be consistent over time, being strongly dependent on the direction of the wind and Koh Rong’s close proximity to the equator in the Gulf of Thailand. (Because the two islands are very close to each other, Koh Rong Samloem’s weather patterns are identical). Between the end of November and the start of March the hot dry weather comes from the north-east direction, while between June and September the rain and wind come from the south-west. The average monthly maximum temperature in the above charts is the average air temperature in shaded areas. As such, Koh Rong temperatures in direct sunlight are much higher. Although the temperatures on Koh Rong do not vary much over the course of a year, humidity on the island varies significantly, with April and May being particularly humid and December and January very dry. The amount of sunshine on Koh Rong and on Koh Rong Samloem is very dependent on the season, with the dry season having significantly more sun than the rainy season.

It’s hard to predict exactly what the weather will be like during these months, but most of the time there will be short burst of heavy rain throughout the day, lasting for about 2 hours or so. Closer to September is when the weather is most volatile – it could rain just during the night or just during the day, it could rain for days at a time or stop for several days straight.

For example, those that visit during the rainy season get to enjoy half-priced accommodation and beautiful rainy scenes, and because it never gets too cold in Cambodia, swimming in the ocean is still a very pleasurable experience (the water rarely drops beneath 25°C).
