Tide Table Charleston — 2026

📘 About Charleston Tide Forecast

In the southern hemisphere, the coastal area of Charleston (New Zealand) is positioned at coordinates -41.90° S and 171.43° E. Its tidal pattern is semi-diurnal (two high and two low tides per day), with a mean tidal range of 1.8m and spring tides reaching up to 2.4m. The broad tidal flats exposed each cycle attract flocks of migratory shorebirds feeding on invertebrates uncovered by the ebb. Mariners in semi-diurnal areas benefit from two high-water windows each day to cross shallow bars or enter marinas. This shoreline is subject to seasonal wind and pressure variations that can affect tide height by up to 0.3m during extreme events.
