Tide Table Subic Bay — 2026

📘 About Subic Bay Tide Forecast

Located in Philippines, Subic Bay sits at latitude 14.77° North and longitude 120.25° East. Its tidal pattern is diurnal (one high and one low tide per day), with a mean tidal range of 0.9m and spring tides reaching up to 1.3m. Oyster and shellfish farmers exploit the 0.5–1.5m range to alternate aerial exposure and submersion in their culture beds. On diurnal coasts, flood and ebb currents tend to be more prolonged, lasting nearly 12 consecutive hours in each direction. This shoreline is subject to seasonal wind and pressure variations that can affect tide height by up to 0.3m during extreme events.

Reported times and heights derive from fundamental harmonic component analysis (M2, S2, K1, O1) applied to these coordinates.
