🏝️ Best Time to Visit the Prettiest Thai Islands
The Andaman Sea on Thailand’s west coast offers different weather than the Gulf of Thailand. The west side gets rain from May to October whilst Gulf islands stay drier. You can visit Thailand year-round if you pick the right coast for the season.

November brings the Loy Krathong floating lantern festival and perfect diving conditions everywhere across Thailand. The Tourism Authority of Thailand provides updated seasonal information for planning your trip successfully.
Local longtail boats connect you between quiet bays where waves lap against weathered wooden hulls rhythmically. These traditional Thai boats have been used by fishermen for generations around the islands. Boat captains know secret snorkelling spots tourists rarely see at Koh Hae near Phuket island. Hiring local operators supports island life and makes your Thailand island hopping experience authentic.
