Port Shelter is a sheltered bay in northeastern Hong Kong, accessed from Sai Kung and the piers at Hebe Haven and Pak Sha Wan. Sites here are shallow, reaching no deeper than fifteen metres, and the calm conditions make this the main area in Hong Kong for beginner training. Sharp Island is the most visited spot, where rocky substrate and coral formations attract butterfly rays, reef fish, and a variety of nudibranchs. Shelter Island offers straightforward shore entry at sites such as Pak Shui Wun and Little Palm Beach. Water temperature drops to around nineteen degrees in winter and climbs to twenty-nine degrees in late summer, so a thin wetsuit is sufficient for most of the year.

Water is coolest from December through February, when temperatures sit around nineteen to twenty degrees and a five-millimetre wetsuit is advisable. From June to September temperatures reach the high twenties, making conditions comfortable in a shorty or thin wetsuit. Visibility is variable across all seasons and can shift between visits, so checking local conditions before departure is worthwhile.
