Solunar tradition: major periods are the ≈3h windows around moon transit and opposition; minor are ≈2h around moonrise and moonset. Pair with the local tide stage and wind for the best read.
A short guide to the coastline at Tern Island — geography, sea state, and what the tide is actually doing under your feet.
Tern Island sits on the Western Australia coast of Australia. The local tide pattern is moderate semidiurnal: from the gridded ocean model TideTurtle samples, the seven-day water-level range reaches about 0.8 m, with the bigger swings clustering around new and full moons.
For anyone visiting Tern Island — surfers, anglers, paddlers, beach-walkers — the tide chart matters in two ways. First, the time of high or low water decides whether the shoreline is exposed or covered. Second, the rate of rise or fall sets how fast currents move in and out of any inlet, harbour or rivermouth nearby. The page below shows both: the next high and low tide times for today, and the seven-day forecast underneath.
Heights on this page are gridded predictions from the Open-Meteo Marine model, normalised to Mean Sea Level (MSL). They are accurate to within roughly 15-30 cm on most days; on storm-surge days the actual water can run higher than the prediction. For safety-critical planning consult official hydrographic services; for everyday surf, kayak, fishing and walking decisions the chart is enough.
Spring tides — the biggest swings of the lunar cycle — happen around new and full moons (twice a month). Neap tides — the smallest swings — land on the quarter moons. If you want the lowest low tide of the month for tidepooling or sandbar walking at Tern Island, look at the seven-day chart for the spring tide.
Quick answers to the most common questions about tide times, range, and water access at Tern Island.
The next high tide time at Tern Island updates daily on this page from gridded Open-Meteo Marine predictions. Look at the highlighted next-high-tide chip at the top of the chart.
Over the next seven days the modelled water-level range at Tern Island is about 0.8 m. Spring tides (around new and full moons) push the range above this average; neap tides (quarter moons) trim it.
Open-Meteo Marine is a gridded global model — accurate enough for everyday surf, fishing, paddling and walking decisions, but not a substitute for an official hydrographic chart. Consult australia's national authority before relying on it for safety-critical use.
