Editorial

About tides at Jack Bay

A short guide to the coastline at Jack Bay — geography, sea state, and what the tide is actually doing under your feet.

Jack Bay sits on the Louisiana coast of United States. The local tide pattern is strong meso-tide: from the gridded ocean model TideTurtle samples, the seven-day water-level range reaches about 3.5 m, with the bigger swings clustering around new and full moons.

For anyone visiting Jack Bay — 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 Jack Bay, look at the seven-day chart for the spring tide.

Common questions

Tide questions about Jack Bay

Quick answers to the most common questions about tide times, range, and water access at Jack Bay.

When is the next high tide at Jack Bay?

The next high tide time at Jack Bay 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.

What is the tidal range at Jack Bay?

Over the next seven days the modelled water-level range at Jack Bay is about 3.5 m. Spring tides (around new and full moons) push the range above this average; neap tides (quarter moons) trim it.

Are these tide times accurate for navigation at Jack Bay?

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 united states's national authority before relying on it for safety-critical use.
