What to wear to Full Moon Party: Koh Phangan sits at 30°C (86°F) by day and 25°C (77°F) at night in January, on beach, with a moderate chance of rain. That means loose natural fabrics and real sun protection, flat sandals you can rinse, with trainers for the night stages, and a bag small enough for the gate rules. The crowd leans beach, neon and rave, so anything that survives the day reads as right.
