Water was clear, inside the bay, and turbid on the outside. I stayed mostly in areas of 4-5 meters depth, at the edge of the bay. However there was almost no wildlife. Besides a few bait fish, HK waters seemed deserted. However, it seemed that coral growth was improving, with more and more coral spots inside the bay. Also, on the sandy parts of the bay, there were large colonies of brown algae, growing 1-2 meters in height. After 45 min I was visibly freezing and left. If the suit had been semi-dry, I would have been much warmer. Still it was nice to be back.
