Da Nang, Central Vietnam tide times

The hero block shows the next high tide at the Tien Sa harbour gauge in local Vietnam time (ICT, UTC+7, no DST). The 7-day table covers all daily highs and lows. The diurnal pattern means most days produce one clear high and one clear low rather than two of each.

Mean range at Tien Sa is about 0.9 metres — a small predominantly diurnal signal. Spring tides push close to 1.4 metres and neaps drop near 0.4. Most days produce one clear high and one clear low; a smaller secondary excursion shows up at certain lunar phases but rarely matters. This is the Gulf of Tonkin and central-Vietnam pattern, smaller than Phuket's Andaman swing across the peninsula.

Open-Meteo Marine, a gridded global ocean model. Useful for planning My Khe and Non Nuoc swimming windows, Hoi An riverside walks an hour south, Son Tra peninsula coastal-road timing, and the Cham Islands snorkel-trip scheduling. For authoritative Vietnamese tide data, the Vietnam Hydrographic Department publishes the official tide tables.

The American military rebranded My Khe as China Beach during the Vietnam War and ran an in-country R-and-R station there from 1965 through 1973. Off-duty US and Australian troops surfed the long shore-break on three-day passes, and the modern Vietnamese surf scene built on that history once the international circuit returned in the 1990s. The break works best on the south-west monsoon offshore wind from May through August. The local board-rental shops on the corniche and the surf schools at the south end of the beach all read the swell and the wind more than the tide.

No. For piloting in or out of Tien Sa or transiting the Han River channel use the Vietnam Hydrographic Department authoritative tide tables, the Vietnam Maritime Administration pilotage guidance, and the National Centre for Hydro-Meteorological Forecasting storm warnings. Typhoon season runs June through November and tropical-storm surge can override the small astronomical signal completely.
