🎣 Solunar Table
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 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. Check the official 2026 tide forecast for Angra Heroismo here, including detailed monthly schedules, peak times, and daily metric swings. In September, Angra Heroismo is in its autumn season, a key period for water sports, fishing, diving, and coastal navigation. Reported times and heights derive from fundamental harmonic component analysis (M2, S2, K1, O1) applied to these coordinates.
