Major Periods (2h)
Minor Periods (1h)
Based on the Solunar Theory (John Alden Knight): fish and wildlife tend to feed more during the periods when the moon is overhead or underfoot (major) and at moonrise/moonset (minor). The score considers the lunar phase and the crossing of major periods with the local high tide.

📘 About Chattogram Tide Forecast
Chattogram is located at 22.27° N, 91.82° E on the coast of Bangladesh, in the northern hemisphere. Its tidal pattern is semi-diurnal (two high and two low tides per day), with a mean tidal range of 2.9m and spring tides reaching up to 4.1m. The 1.5–3m range generates noticeable channel currents that paddlers and racers must account for when planning routes. 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 bulletin for Chattogram delivers a thorough schedule of sea level swings with hourly marks for the entire year. In September, Chattogram is in its autumn season, a key period for water sports, fishing, diving, and coastal navigation. Astronomical tables for this site are processed using tidal harmonic algorithms and adjusted for regional bathymetry.
