Monsoon Season

The rainy season in much of Thailand runs from May to October, with September and October being the height of the monsoon season. The rainy season in Koh Samui and the south east of the Thai peninsula runs from November to March.

Torrential rain and widespread flooding often result in flash floods and mudslides in Thailand. You should exercise caution and follow the advice of local authorities. Flooding also affects the southern tourist areas of Phuket, Krabi and Koh Samui. You should check with the Thai Meteorological Department (Thai Meteorological Department) for up-to-date information or with your tour operator before travelling to affected areas.

The Mekong River Commission, an international organisation, posts official updates on the Mekong River on their website.

When visiting Lake Caves, particularly during the rainy season, you should be aware that they are prone to dangerous flash flooding. On 13 October 2007 eight people died, including one British national at Khao Sok National Park following a flash flood.

If you are considering jungle trekking you should also ensure that you use reliable licensed tour guides.
