Koh Samui Weather

Unfortunately, visitors are sometimes incorrectly informed about the seasons of Koh Samui prior to their departure from their home. It is unaware by most of the visitors. For instance, we do not have the same rainy season as it does in Bangkok and other parts of Thailand..
During the high season, from December to February, temperatures on Koh Samui can reach up to 30?C (86?F). Some tropical rain showers occur sometimes in November and a little bit in December. This is the best season for European people as the weather is comparatively cooler than the rest of the year.
