After Phuket and Ko Chang, Ko Samui is the third largest island in Thailand. Only 35 kilometers separate the coconut palm island from the mainland. Due to its geographical proximity to the equator, the climate here is tropically warm all year round. The best time to travel is from January to the beginning of May. Temperatures of up to 40 degrees are then not uncommon, which of course also affects the water temperature. Since Ko Samui is located in a tropical climate zone, the weather is humid and changeable all year round. The rainy monsoon season begins in mid-October and ends in December. During this time, rainfall can be so heavy that even the operation of the ferries is impossible.
The island is especially famous for its miles of white dream beaches and the typical coconut palm belt. Especially scuba divers appreciate the natural underwater world of the Gulf of Thailand. Nature lovers appreciate the untouched picturesque natural landscape. But also families will find ideal conditions for a dream vacation on the island, because here they can experience unlimited bathing fun in addition to Thai culture. Especially the wide and well-kept beaches Chaweng Beach and Lamai Beach attract with warm water temperatures, numerous water sports attractions and ideal snorkeling opportunities. The island has a lot more to offer besides bathing fun and water sports, such as the landmark of Ko Samui, a 12 meter high Buddha statue made of gold or the impressive Mu Ko Ang Thong National Park.
From late March to early June, it is extremely hot on the Asian dream island. Even the otherwise heat-resistant Thais then seek shelter and cooling in the shade. Those who do not tolerate great heat and sultry climate well should therefore avoid traveling at this time. Especially older travelers should better choose another travel date. Here, the months of July to October would come into consideration, where the temperatures are in the average range. However, during this time there are so-called monsoon rains. This is not a continuous rain as it is usual in Europe but it usually rains only one or two hours in the afternoon. After that, the sun comes out again. The most abundant rainfall occurs in November. However, according to the State Meteorological Office, it has rained comparatively rarely and only in small amounts in recent years. Thus, nothing stands in the way of a trip to Ko Samui even during the rainy season. Somewhat cooler are the months of November to February, the right time to escape the cold European winter.
