Scuba Diving Regions in South Korea
From world-class walls to muck diving havens, discover the unique character of each regional cluster.
Regional Diversity
Diving in South Korea is seasonal due to the significant variations in water temperature. The prime season is from June to October, when the water is warmest and visibility is generally at its best. In Jeju, the water temperature can reach up to 26°C in late summer. The winter months (December to March) see water temperatures drop significantly, particularly on the mainland, requiring specialized exposure protection (drysuits are common). However, winter can offer the clearest visibility in the East Sea. Always check regional weather patterns, as the late summer can occasionally bring typhoons.
Planning Tips
Many regions are seasonally dependent. For South Korea, the best diving conditions are usually spread across different months depending on the archipelago or coast.
