· 1 min read Practical
Thailand’s geography creates distinct regional weather patterns — the Andaman Coast (Phuket, Krabi, Koh Phi Phi) and Gulf Coast (Koh Samui, Koh Phangan) have opposite monsoon seasons. Understanding which applies to your destination in December is the key planning question.
Weather in December
Peak dry season on the Andaman Coast. Excellent weather almost everywhere. Christmas–New Year is the busiest and most expensive period — book well ahead or visit early December.
