Koh Samui Weather

The best time of the year to visit is from December through to August. The rainy or monsoon season is from September to the end November. That said the temperatures are always hot and Thailand boasts a near 12-month tourist season. You are guaranteed warm weather!

The climate is very pleasant all year round, with temperatures varying between 25 and 34 degrees Celsius.

There are three seasons, warm and dry season from February till May, rainy season from the end of September till November and "cooler" season, which extends from October till January.

From February till October, the average temperature is from 32 to 38 degrees, but from July till September, there can be some showers. The rainy season often amounts in fact to some "refreshing" showers followed by the return of the sun.

The climate is tropical so very humid all year round, but Samui remains always refreshed by a pleasant sea breeze blowing from the Gulf.

If you love the sun, Samui is the place...
