Cô Tô has no tide station nearby: its tide is calculated with the global FES2022 model, from the nearest model cells offshore (the first one 2.1 mi away). It may differ from the real tide by a few minutes and inches, and more with wind or storms. Heights are above mean sea level, not chart datum, so low tides are negative. Not for navigation.
