Krabi vs Koh Samui is a decision about two different coasts. Krabi sits on the Andaman Sea, on Thailand’s west coast, with limestone cliffs and island hopping. Koh Samui is an island in the Gulf of Thailand, on the east side, with long palm-fringed beaches, upscale resorts and a more developed tourism scene. The biggest difference is often the weather: the two coasts have different rainy seasons.
We live on Samui and know both coasts well. This comparison covers seasons, beaches, scenery, day trips, hotels, families, nightlife and access, with a verdict for each type of traveller.
Verdict: choose Krabi from November to April for karst scenery and island hopping; choose Koh Samui for long beaches, resorts and a reliable dry spell from roughly January to September (including the Andaman monsoon months). With time, do both: a bus-and-ferry route links them in a day.

Krabi vs Koh Samui: Weather and Seasons
The Andaman coast, including Krabi, has its main rainy season from about May to October, driven by the south-west monsoon. The Gulf coast, including Koh Samui, has a different pattern: its wettest months are usually October to December, while much of the Andaman monsoon period is relatively dry on Samui. That makes Samui a strong choice in July and August, and Krabi ideal from December to April.
