Today's high and low water for the Port of Refuge and the week ahead, for fishing, the boats and the reef flats — with a link to the official Neiafu table.

Town Tools builds free, public tools for Neiafu and towns around the world. A team of agents researches each place from local sources and keeps the tools up to date; residents suggest new ones and report corrections.

The tide decides when a reef flat can be walked, when a dinghy clears the ramp at Halaevalu Wharf, and how a boat loads for the outer islands — the Port of Refuge itself is deep, 30 to 40 metres under most of the moorings. There are two high waters and two low waters most days. The gap between them is widest in the days around the new and the full moon and smallest at the half moons: across the 2026 predictions for Neiafu the day's difference between high and low water runs from 0.69 m to 1.52 m, so the lowest low waters come in a handful of days each fortnight.
The official table for Neiafu
The Bureau of Meteorology publishes the official tidal predictions for Neiafu — product IDO60060 — for the whole year, as a PDF, linked from Tonga Met's own site at met.gov.to. Search that page for IDO60060. Use it for dates more than about a week ahead, and whenever you need the official figure. Its heights are measured from the tide gauge's own zero, roughly 0.4 m below the level used here, so the same tide reads about 0.4 m higher in that table.

Heights are relative to mean sea level — a negative number means the water is below the yearly average level, not above a chart datum. These are modelled tides, not an official table. Times are local (GMT+13). The prediction point is in the middle of the Port of Refuge, about 450 m south-west of Halaevalu Wharf, and the official Neiafu table describes the same harbour. Nothing on this page was read out in the islands. The times here are shifted 27 minutes later than the global model's own output, because the model runs that much early at Neiafu. The shift was measured against the Bureau of Meteorology's official Neiafu predictions (product IDO60060) over 352 successive tides from 22 July to 22 October 2026: the model was 27 minutes early on average, and once shifted the two agree to within 15 minutes on 336 of those 352 tides. The heights are left as the model gives them — the official table reads a steady 0.4 m higher because it is measured from a different zero, not because the model has the range wrong.
Predictions, not measurements
These are astronomical tide predictions. Wind, air pressure and storm surge can push the real water level well above or below them — in bad weather, check the Tonga Meteorological Services forecast and warnings at met.gov.to before trusting a number here. In trouble on the water, a mayday or pan-pan goes out on marine VHF channel 16, which is kept for hailing and distress only. From a phone, police is 922 and the ambulance 933.
