Best Time to Dive
Planning your visit to Koh Moan involves considering the distinct seasons that shape dive conditions.

During these months, air temperatures hover around a comfortable 27-29°C (81-84°F), while rainfall remains minimal, often less than 3 mm. Wave heights are generally lower, and winds are moderate, contributing to more predictable surface conditions. Water temperatures, not consistently reported with exact values, typically reflect the warm tropical air. As the year progresses from May to November, dive scores shift to "Good." This reflects an increase in wave heights, wind speeds, and notably, rainfall, which can reach up to 17 mm in September. Visibility can fluctuate more during these wetter, windier months. For optimal comfort and calmer seas, targeting the drier, less windy periods is advisable.
