Major Periods (2h)
Minor Periods (1h)

📘 About Sian Ka an Tide Forecast
Situated along the coastline of Mexico (19.31° N, 87.45° W), Sian Ka an lies in the northern hemisphere. Its tidal pattern is semi-diurnal (two high and two low tides per day), with a mean tidal range of 0.1m and spring tides reaching up to 0.2m. With tidal range under 0.5m, currents here are weak — ideal for diving and kayaking in sheltered waters. Bathers and stand-up paddlers can choose between morning and afternoon high tides for calm-water conditions. Intense weather events such as storms can create temporary storm surges that add to the astronomical high tide. The 2026 tidal schedule for Sian Ka an provides a full-year calendar of high and low waters alongside predicted sea levels. In September, Sian Ka an is in its autumn season, a key period for water sports, fishing, diving, and coastal navigation. MaréAgora calculations use harmonic decomposition calibrated via satellite altimetry and local gauges to ensure high accuracy.
