Thailand: Weather & when to go: August

August Overview

August is traditionally the wettest month in Thailand, with temperatures hovering in the mid 20s to low 30s. Rainfall is at its heaviest across the north, with downpours covering the area between the Golden Triangle and Chiang Rai all the way west to Chiang Mai. Trekking is exceedingly wet during this time of the year, and can prove to be impossible in some parts of the country. For those seeking to trek in the north during this time, be sure to speak ahead of time with our representatives to see where it is still possible.

In the beach getaways of Koh Kood, Koh Chang, Krabi and Phuket, the weather still is at its worst, with heavy rains covering the region. For those planning a beach getaway, it’s best to move plans to the other side of the peninsula, where sunny, dry days are still a common occurrence. From Koh Samui and Koh Phangan to Hua Hin and Cha Am, this is one of the final dry months for beach weather.
