Coast, Cheung Chau, Islands. We calculate high and low water here from an ocean tide model — accurate to about 5 cm on open coasts, considerably less in tidal flats and river mouths. The authority assesses this spot weekly. The sample of 2026-08-21 came out: good. That is a snapshot, not an annual classification.
