Typical weather, averaged over 30 years (1995–2024), read 17 km north of Koh Rong. Its own grid square is mostly sea and holds only a daily average, so the page reads the nearest square with a true high and low near the town's height. Temperatures are adjusted against 66 weather stations: daytime highs read about 3.1°F cold in the source data and are raised to match.Temperatures are adjusted against 66 weather stations: daytime highs read about 1.7°C cold in the source data and are raised to match.
