The weather in Ranong
Ranong has a tropical monsoon climate with little variation in temperature throughout the year, although the pre-monsoon months (February to April) are a little warmer during the day. The rainy season (from May to October) is very marked with torrential rains and heavy precipitation in the transition months of April and November.
The best time to come to Ranong and its islands (Koh Chang and Koh Phayam) is from December to the end of March. The period from May to October is particularly not a good time to come, rains are very important.
