Visiting Koh Lanta in May
May marks the start of the wet season on Koh Lanta. Rain becomes more frequent, seas roughen, and many businesses begin closing. Early May still offers workable conditions, but by late May the island is transitioning into its off-season rhythm. Prices drop significantly and the island becomes very quiet.

common questions
FAQ — Bali in May
Is it worth visiting Koh Lanta in May?
Depends on your priorities. Early May can still offer good conditions with significantly lower prices and crowds. Late May is genuinely wet — heavy rain, rough seas, and reduced activities and restaurant options. Budget travellers comfortable with unpredictable weather and a quiet island can find May very rewarding. Those wanting beach and diving conditions should stick to November–April.
