📘 About Portsmouth Tide Forecast

With geographic coordinates of 50.82° N, 1.09° W, Portsmouth is a key coastal reference in Reino Unido. Its tidal pattern is semi-diurnal (two high and two low tides per day), with a mean tidal range of 2.5m and spring tides reaching up to 3.3m. With 1.5–3 metre swings, high tide floods extensive tidal flats while low tide reveals coastal habitats important to local wildlife. Mariners in semi-diurnal areas benefit from two high-water windows each day to cross shallow bars or enter marinas. The continental shelf morphology in this area amplifies or attenuates tidal waves arriving from the open ocean.
