Climate

Koh Chang is the ideal location for the real rest as the weather there is very comfortable with warm temperature most of the time. Koh Chang is influenced by the northeastern and southwestern winds which sometime limit sea transports to a group of islands. That triggers limitations to the water transportation to the group of islands.

Between May and October which is the period of southwestern monsoons, the west coast is always visited by storms and thus, not safe for ferries and small boats. However, visitors can still visit the islands via the normally more popular routes, most of which are to the northeast of Koh Chang anyway. Some of the islands south of Koh Chang may be unreachable on some days during this time. Seek the advice of experienced locals before embarking on an excursion to these smaller islands.

Between November to early May is very safe because there are less rain and strong winds. Most of Trat areas lie in the Gulf of Thailand. This makes the province abundant with tourism resources. Trat has as many as 52 islands, especially Koh Chang include sea, waterfalls and forest. The province is also the source of red sapphire, fine shrimp paste and sweet rakum, a kind of palm of genus Zalacca with sweet and acid taste. The province of Trat, host of the Koh Chang archipelago, is located within the Gulf of Thailand which has a tropical climate. The annual average temperature is 27.3 c with an average high of 31.3 c and an average low of 23.2 c. Mid-November to February is the cool, dry season when the temperature is at its lowest, especially in Januaray when it averages at 21 c. March to May is the hot and humid season. The hottest month, as with most parts of Thailand, is April when the temperature hits an average high of 32.9 c but can reach as high as 38 c. Towards the end of May till October is the wet season, when you can expect more rain, although not all the time. The best season to holiday in Koh Chang is from November to May mainly because of much more sunshine. Other periods of the year do attract visitors to the Koh Chang Marine National Park as well, even though they are aware of possible rains and storms from time to time.
