We planned to drift along the wall at Saekki-seom(새끼섬) when the tide changed from low to high, but we were lucky and hit slack tide during the dive. Thanks to that, we could look at the wall of Saekki-seom very carefully. We stayed around 15–20 m depth and enjoyed finding many attached creatures and small macro life like nudibranchs. The surface water was 29 °C and even at 20 m it stayed above 25 °C. It was warm and perfect for Jeju’s high diving season, and we enjoyed this great spot very much. Our buddies could dive comfortably in 3 mm suits, and the DiveMap team even enjoyed Munseom with only rash guards during the high season. Now the real high season has begun. Please come to Jeju and enjoy its beautiful sea and wonderful diving!
