Tide Table Angra Heroismo — 2026

📘 About Angra Heroismo Tide Forecast

Situated along the coastline of Portugal (38.65° N, 27.24° W), Angra Heroismo lies in the northern hemisphere. Its tidal pattern is semi-diurnal (two high and two low tides per day), with a mean tidal range of 0.7m and spring tides reaching up to 1.1m. Oyster and shellfish farmers exploit the 0.5–1.5m range to alternate aerial exposure and submersion in their culture beds. The semi-diurnal cycle flushes coves frequently, shortening water residence time and maintaining high oxygenation levels. Tidal dynamics in this bay or inlet are shaped by the geometry of its entrance, which can amplify or reduce range relative to the open sea.
