What to know for December

Beach and sea conditions at their best

December falls in the dry northeast monsoon. Seas are calm, visibility for snorkelling and diving is strong, and beach days are reliable. This is the peak window for water sports including kite surfing on the south coast, kayaking, and day trips to Sail Rock and Ang Thong Marine Park.

Book ahead — especially around Full Moon

Peak season means high demand. Accommodation at Thong Nai Pan, Haad Rin and popular west-coast villas fills up weeks ahead around Full Moon Party dates. If your dates coincide with a full moon, plan earlier than you think necessary.

Wellness runs year-round

The yoga and wellness scene on the west coast operates regardless of season. Drop-in classes, sound baths, ecstatic dance and multi-week retreats continue through peak months — and many people combine a beach-focused stay with a few days of morning practice.
