Method and sources
Times are calculated on your device, rounded to the nearest minute in Vietnam time (UTC+7), for dates from 2000 to 2099. The tool uses the USNO solar-coordinate equations and the 90.833° sunrise/sunset zenith convention from NOAA. These are estimates, not on-site observations.
Representative coordinates from GeoNames: Con Son: 8.68497° N, 106.60781° E; Vung Tau: 10.34599° N, 107.08426° E. Viewing times may differ at other locations in the area.
Vung Tau tide calendar
Calculate daily or monthly high and low tides on your device. These are astronomical predictions for the Vung Tau station, not a Hon Ba walking-access timetable.
Preparing the calculator…
Vietnam time (UTC+7). Heights are metres above model LAT, not Seamark’s chart datum or a verified port datum. Do not directly compare heights from sources using different datums. Calculator date range: 2026–2027.
Data, method and limitations
Calculated locally using the Slackwater engine (MIT), version 1.0.0-beta.0. Station ticon/vung_tau-383-vnm-uhslc_fd, 10.34° N, 107.072° E; 50 TICON-4 harmonic constituents. Source observation period: 15 October 2007–30 June 2025. Data snapshot retrieved 10 November 2026; not live observations or automatically updated data.
LAT means Lowest Astronomical Tide in the model. The original station datum frame is gauge; the engine handles conversion. Harmonic predictions do not replace on-site checks or current warnings from Vietnam’s National Center for Hydro-Meteorological Forecasting (Vietnamese).
