Phuket has two main diving seasons: the dry season (high season) from around November to April, and the green season from around May to October. During the green season, the southwest monsoon can occasionally bring stronger waves to offshore areas depending on the day’s sea conditions.
However, this season also offers its own unique appeal, especially around the Racha Islands, where divers can still enjoy crystal-clear blue water and excellent visibility on many days. Around the Phi Phi Islands, many dive sites are sheltered by dramatic limestone cliffs, allowing for comfortable diving conditions even during the green season when conditions are favorable.
Koh Haa is well known for its exciting topography diving, featuring caves, caverns, and swim-throughs. In contrast, Hin Daeng and Hin Muang are famous as dynamic offshore dive sites with stronger currents, attracting large schools of fish and pelagic species.
Please note that the Hin Daeng and Hin Muang area is located in offshore waters and may be affected by waves and swells depending on sea conditions.
