🇰🇷 South Korea

South Korea is a year-round option for scuba divers who are comfortable with cold-temperate water. Diving is mainly coastal, with access along the Yellow Sea and the Japan Sea (East Sea), plus offshore areas depending on local conditions. Water temperatures are typically cooler than in tropical destinations, so thick exposure protection is common, and visibility can vary with season and weather. The shore and island sites around the main marine regions are used for recreational diving, and some areas can be good for observing local temperate species and seasonal changes. In practice, many trips are organized from major coastal bases such as Busan, with dive boats depending on the site and current conditions.
