Tide Table Rota Island — 2026

📘 About Rota Island Tide Forecast

The coordinates for Rota Island (14.13° N, 145.13° E) place this stretch of Northern Mariana Islands's coast in the northern hemisphere. Its tidal pattern is semi-diurnal (two high and two low tides per day), with a mean tidal range of 0.6m and spring tides reaching up to 0.7m. The intertidal zone hosts benthic communities adapted to moderate salinity and temperature swings across tidal cycles. The semi-diurnal cycle flushes coves frequently, shortening water residence time and maintaining high oxygenation levels. This coast is subject to longshore drift currents that distribute sediment and shape beaches throughout the year. The 2026 tidal schedule for Rota Island provides a full-year calendar of high and low waters alongside predicted sea levels. In July, Rota Island is in its summer season, a key period for water sports, fishing, diving, and coastal navigation. All tide predictions are computed from harmonic constants validated for this coastal station, with accuracy within ±15 minutes for most conditions.
