When to go
Koh Lipe follows the Andaman pattern: a calmer dry season that drives most diving and ferry traffic, and a wetter monsoon season that can reduce visibility and limit crossings.
Best overall window
Dryseason pattern with calmer seas and better boat reliability. Water often 28°C and winds commonly around 10 km/h to 20 km/h.
Outside that window
Southwest monsoon brings more rain and wind (often 20 km/h to 30 km/h), choppier seas, and higher chance of cancellations.
Start with the overall answer, then switch only when scuba, freedive, snorkel, or topside timing changes the trip in a meaningful way.
The overall row stays visible so you can compare it against the currently selected scope.

These do not replace the overall planner. Use them only if a specific animal or event is driving your trip dates.
