Plan Your Trip

The best times to go snorkeling on Koh Tao, Thailand, are generally during the dry season, which spans from February to late September. This period is characterized by clear skies, calm seas, and excellent underwater visibility, making it ideal for snorkeling. It's important to note that outside of these months, from October to January, Koh Tao experiences its monsoon season. During this time, rough seas and reduced visibility can make snorkeling less enjoyable and sometimes unsafe. When planning a snorkeling trip to Koh Tao, it's also a good idea to consider factors like marine life activity and tourist seasons. Certain months may offer higher chances of encountering specific marine species, while others might be more crowded with tourists. Generally, the best balance of good weather, clear waters, and fewer crowds is found in the late spring and early summer months.
