Diving is possible all year round on Koh Phangan, as it is all around the Gulf of Thailand, thanks to its tropical climate and warm ocean temperatures no matter the season. The island usually experiences a dry season and a very wet season, though there are three notable seasons; the dry, cooler peak season that lasts from December until March, the wet low season, running from September to the end of November, and finally the hot season, which is in the middle in terms of tourist numbers and typically starts in April and ends in June.
Sea temperatures are comfortable all year round, normally lingering around 28°C-30°C (82°F-86°F). Air temperatures similarly rest around the same for most of the year, with the exception of the hot season, during which temperatures can sometimes soar into the 40s Celsius (low 100s Fahrenheit).
Though diving is excellent throughout the year, the best time is said to be in the dry, cooler season, due to greater visibility underwater and comfortable water and air temperatures. Rainfall is also much lower, so diving trips are less likely to be interrupted by bad weather. In terms of marine life, it remains mostly unchanged throughout the seasons.
