When to Come and What to Expect

The deals follow the Similan and Surin national park season, 15 October 2026 to 15 May 2027. Every part of it has something different to offer.

  • Opening (mid-October – November) — The national parks reopen after the monsoon. Boats are quieter and conditions settle week by week.
  • Peak (December – February) — Typically the calmest seas and clearest water of the year — the busiest and most popular time to dive.
  • Late season (March – mid-May) — The warmest water, and often the best chance of manta rays and whale sharks around Koh Bon, Koh Tachai and Richelieu Rock.
