Its tidal pattern is mixed semi-diurnal (unequal tidal heights across the day), with a mean tidal range of 0.6m and spring tides reaching up to 0.9m. With tides reaching up to 1.5m, local fishers typically work around the two hours flanking high tide to benefit from stronger flow. Mixed tides blend characteristics of diurnal and semi-diurnal patterns — the morning tide may differ greatly from the afternoon tide in height and current. Coastal water salinity varies with rainy seasons, creating gradients that influence the distribution of marine species.
