Climate and Weather of Thailand

Thailand has a tropical climate, and the weather varies by season. In the colder season (November - February), the average maximum temperatures range between 28°C and 33°C, while during the summer (March - May), you can expect temperatures between 30°C and 37°C.

Rainy season in Thailand

The rainy season on the east coast of Thailand, particularly in areas such as Koh Samui, Koh Phangan, and Koh Tao, typically occurs from October to December. This is due to the northeast monsoon, which brings heavy rainfall and rough seas during these months.

May marks the start of the rainy season on the west coast, lasting until the end of October. Usually, the rain showers here are short but bring very heavy downpours. September and October are, on average, the wettest months throughout the country.

Does Thailand experience hurricanes or cyclones?

Thailand has the potential to experience typhoons or cyclones. Cyclones form between April and December over the Indian Ocean. However, since they mostly move in western, northwestern, and northern directions, they do not typically reach mainland Thailand. If they do, the chances are higher at the beginning and end of the cyclone season.
