📘 About Port Blair Tide Forecast

With geographic coordinates of 11.68° N, 92.77° E, Port Blair is a key coastal reference in India. Its tidal pattern is semi-diurnal (two high and two low tides per day), with a mean tidal range of 0.5m and spring tides reaching up to 0.8m. Oyster and shellfish farmers exploit the 0.5–1.5m range to alternate aerial exposure and submersion in their culture beds. The regularity of semi-diurnal tides — two highs and two lows approximately 6 hours apart — simplifies crossing planning and fishing scheduling. The continental shelf morphology in this area amplifies or attenuates tidal waves arriving from the open ocean.
