Tide Table Otaru — 2026

📘 About Otaru Tide Forecast

With geographic coordinates of 43.21° N, 141.01° E, Otaru is a key coastal reference in Japan. Its tidal pattern is diurnal (one high and one low tide per day), with a mean tidal range of 0.2m and spring tides reaching up to 0.3m. Beaches here have very narrow intertidal zones, with only a few metres between high and low water marks. The diurnal pattern is relatively rare worldwide, occurring mainly along Gulf of Mexico coasts, northern Australia, and parts of Southeast Asia. Coastal water salinity varies with rainy seasons, creating gradients that influence the distribution of marine species. This page shows the complete 2026 tide table for Otaru, with precise high and low tide times and heights in metres for every day of the year. In July, Otaru is in its summer season, a key period for water sports, fishing, diving, and coastal navigation. Predictive modeling employs updated local oceanic constants, ensuring minimal margin of error in peak tidal timing.
