Andaman Coast vs Gulf Coast Comparison
Thailand's tropical islands are divided across two completely distinct bodies of water with opposite monsoon weather patterns:
- Andaman Sea (Phuket, Krabi, Koh Phi Phi): Towering limestone karst cliffs, direct international flights to Phuket, world-class beach clubs, and island-hopping tours. Peak dry season runs from November to April.
- Gulf of Thailand (Koh Samui, Koh Phangan, Koh Tao): Coconut-fringed bays, luxury pool villas, diving schools, and Full Moon parties. Protected from the southwest monsoon, making it the best summer holiday choice from May to August when the Andaman coast experiences rain!
Island Personality Breakdown
- Phuket: Largest island with luxury resorts, water parks, shopping malls, and direct flights from India.
