Tide Table San Martin — 2026

📘 About San Martin Tide Forecast

San Martin is located at -68.13° S, 67.10° W on the coast of Argentina, in the southern hemisphere. Its tidal pattern is diurnal (one high and one low tide per day), with a mean tidal range of 1.1m and spring tides reaching up to 1.3m. The small tidal range makes anchoring small fishing boats straightforward, as the same spot remains accessible throughout the day. The diurnal cycle promotes heat buildup in coastal lagoons during the long daily low tide exposure. Waters along this coast are influenced by events such as El Niño, which can temporarily raise mean sea level. The 2026 tidal schedule for San Martin provides a full-year calendar of high and low waters alongside predicted sea levels. In October, San Martin is in its spring season, a key period for water sports, fishing, diving, and coastal navigation. Reported times and heights derive from fundamental harmonic component analysis (M2, S2, K1, O1) applied to these coordinates.
