Koh Samui Weather Forecast

rainy season in ThailandKoh Samui’s weather is a little different than the rest of Thailand and has three distinct seasons: hot, rainy and really hot.

Rainy season
Koh Samui is a tropical island.  Inland parts of Koh Samui are a dense tropical forest, so expect rain at anytime in any month on Koh Samui.  The time of heavier and more consistent rain known as monsoon season is October through to mid December.

Dry season
When the rains stop and the plants grow wild and beautiful is the dry season, or as the Thais calls it, winter.  Winter on Koh Samui is usually 30C / 85F and sunny.  This season is typically mid December through March.

Hot season
dry season in ThailandWhen the ground has dried from a lack of rain and sand dusts the road, the hot season has started.  The sun overhead is brighter and hotter than usual.  Many tropical fruits ripen during this season.  This season starts in April and lasts until the cooling rain, which begins in September / October.
