Model-derived from a global ocean grid. Useful indication; expect about ±45 minutes on average vs. a local harmonic gauge, individual stations vary widely. See /methodology for per-region detail. Not for navigation.

The angler tradition for major/minor fishing windows: major ≈3-hour windows around moon transit and opposition; minor ≈2-hour windows around moonrise and moonset. Times are Pacific/Efate local. Folk tradition, not a scientific forecast.

Next spring tide on Mon 18 May (range 1.4m). Next neap on Sun 17 May.

Spring tides cluster around new and full moons (biggest swings). Neap tides land on quarter moons (smallest swings). See the spring tide and neap tide glossary entries for the why.

Lenakel is the main town of Tanna Island, the southernmost of Vanuatu's main inhabited islands and one of the most geologically dramatic places in the Pacific. The town sits on the west coast, facing the Coral Sea with a reef-fringed shore that absorbs the trade-wind swell arriving from the southeast around the island's southern tip. The defining feature of Tanna is Mount Yasur — an active stratovolcano 12 km inland from Lenakel, erupting in some form on approximately 60% of days. Lava bombs, ash plumes, and the orange glow of the summit crater at night are visible from the coast on clear evenings. The access road to Yasur from Lenakel crosses a black-ash plain — White Grass Road — and reaches the crater rim in about 40 minutes. The tidal regime at Lenakel is mixed semidiurnal consistent with the regional Vanuatu pattern. Spring range approximately 1.0–1.2 m above Chart Datum; neap range 0.4–0.5 m. The west coast of Tanna faces the dominant trade-wind direction and receives the prevailing southeast swell refracted around the island's south tip — this means the actual water-level envelope at the shore is tide plus swell run-up, and on days when southeast swell is running at 1.5–2.0 m, the effective shoreline position is 0.5–1.0 m higher than the tidal prediction alone suggests. Port Resolution on Tanna's east coast (not served by TideTurtle from Lenakel, but relevant context) is the primary small-boat anchorage for visiting yachts; Lenakel's west-coast waterfront is the main town pier and supply-ship landing. The supply ship from Port Vila calls roughly monthly; the tidal state governs whether it can come alongside the pier at all — the pier is shallow-draught and at very low spring water (below 0.2 m above Chart Datum) the inner approach silts up enough to restrict draft to less than 2 m. For anglers, the Lenakel reef edge is the primary target. A small boat out through the pass at the north end of the reef flat reaches 20–40 m of water within 500 m of the reef edge. Wahoo, mahi-mahi, and yellowfin tuna are the offshore targets; trolling the reef edge on the flood as oceanic water pushes over the reef crest concentrates baitfish and triggers feeding. Shore casting from the breakwater south of the town pier targets trevally and snapper at dawn and dusk. The ebb current along the reef face on spring tides reaches 1.5–2.0 knots — use heavier jig heads to maintain contact with the bottom structure. Kayakers at Lenakel must treat the exposed west coast with respect. Trade-wind swell arrives at the reef break 200–400 m offshore; inside the reef the lagoon is calmer but not flat. Launch from the town beach in the morning before trade winds build. The lagoon inside the reef is paddleable at gauge readings above 0.5 m; at lower levels shallow coral heads create navigation hazards. Circumnavigation of Tanna is a multi-day expedition requiring offshore passage experience — not a day-trip from Lenakel. Photographers come to Lenakel primarily for the Yasur access, not the coast. However, the combination of volcanic coastline and active volcano creates unique images: the black-sand and boulder beaches south of Lenakel at low spring water expose substrate that appears nowhere else in the Pacific, and on clear nights the Yasur glow illuminates a strip of the western sky above the island silhouette. Night photography from the Lenakel pier at low spring water puts the black foreground boulder beach, the dark lagoon, and the volcano glow into a single frame. Cyclone season (November–April) means that Lenakel's exposed west coast can experience direct cyclone approach without the barrier-reef attenuation that protects Port Vila. Tanna was devastated by Cyclone Pam in 2015. During cyclone season, the tidal prediction provides the astronomical baseline, but storm surge in a cyclone approach adds 1–3 m without warning. All tide predictions for Lenakel come from the Open-Meteo Marine gridded model. Timing accuracy is ±45 minutes; height accuracy is ±0.3 m above Chart Datum.
