An island vacation on Koh Samui sounds well and truly relaxing but finding the best time to visit will depend on what you’re after. Do you plan to stay indoors, or go adventuring? Understanding the nuances of the island’s seasonal weather patterns is important for this so here’s a quick breakdown.
The Dry Season
Running from December to February, the dry season is considered by many to be the best time for a visit. The weather is sunny with little to no rainfall, and the perfect conditions for beach days and watersports at resorts like NH Collection Samui Peace Resort.
The Hot Season
This season – from March to May – is when the temperatures are at their highest, often going beyond 30°C. But this is also when Songkran (Thai New Year) is celebrated, so you can look forward to cultural ceremonies, street celebrations and yes, water fights, all from your resort in Koh Samui.
The Rainy Season
Extending from June to September, the rainy season brings frequent but short bursts of rain, especially in the late afternoon or evening. But many outdoor activities continue including cooking classes, yoga retreats and cultural tours, with the added benefit of fewer tourists.
The Monsoon Season

October to November has the heaviest rainfall along with some pretty strong winds. If you’re the type who prefers to stay indoors, then the Monsoon season is an ideal time to visit. Without the tourist crowds you’ll truly be experiencing a quieter, more serene island escape here.
