What's the weather like in Koh Tao in September?

Koh Tao is a small island located in the Gulf of Thailand. The island has a more relaxed vibe than nearby Koh Samui and Koh Phangan but is still a popular tourist destination, especially for those who want to give diving a go; Koh Tao has some of the best diving spots in the whole of Thailand and many diving schools. The island's sub-tropical climate is also a big draw to sun worshippers.

Rain

September marks the end of the South West monsoon and the beginning of the North East monsoon winds. These bring heavy rains and tropical storms from September to November, which is why these months are known as the wet season. September actually has a lower rainfall average compared with August but that level will increase in the next two months. The average rainfall is 141mm with around 18 days of rainfall a month and a 36% chance of wet weather. The rain often comes in heavy afternoon storms which pass quickly.

Temperature

Temperatures are fairly consistent throughout the year in Koh Tao and remain high in September. The average temperature is the same as August, at 28°C with highs reaching 31°C. Nights are a little cooler, with an average low of 24°C. Humidity levels are also high, which means that the heat can feel very sticky at times. 

Sea Temperature

The water around Koh Tao also remains warm this month, with an average sea temperature of 29°C. This provides perfect conditions for swimming, snorkelling and diving in comfort.

Clouds

Like the rest of Thailand, Koh Tao enjoys sunshine all year round. Cloud cover it quite high in September, at 63%, but holiday makers will still be able to enjoy 6 hours of full sunshine every day.
