Tide Table Kolkata — 2026

📘 About Kolkata Tide Forecast

Kolkata is located at 22.57° N, 88.36° E on the coast of India, in the northern hemisphere. Its tidal pattern is semi-diurnal (two high and two low tides per day), with a mean tidal range of 1.6m and spring tides reaching up to 2.2m (values estimated from nearest harmonic station). The 1.5–3 metre tidal range significantly affects navigation for small vessels, which should consult the tide table before crossing shallow bars. The regularity of semi-diurnal tides — two highs and two lows approximately 6 hours apart — simplifies crossing planning and fishing scheduling. This location is part of a coastline continuously monitored by automated tide gauge networks. The 2026 tidal schedule for Kolkata provides a full-year calendar of high and low waters alongside predicted sea levels. In September, Kolkata 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.
