Baseado na Teoria Solunar (John Alden Knight): peixes e animais silvestres tendem a se alimentar mais nos períodos em que a lua está a pino ou no fundo (maiores) e no nascer/poente da lua (menores). A pontuação considera a fase lunar e o cruzamento dos períodos maiores com a maré cheia local.

📘 About Portneuf Tide Forecast
Portneuf is located at 46.68° N, 71.88° W on the coast of Canada, in the northern hemisphere. Its tidal pattern is semi-diurnal (two high and two low tides per day), with a mean tidal range of 3m and spring tides reaching up to 3.7m. The high amplitude results from resonance between the ocean basin and the natural oscillation period of the local estuary or bay. Mariners in semi-diurnal areas benefit from two high-water windows each day to cross shallow bars or enter marinas. The speed and direction of tidal currents here vary seasonally with the region's prevailing winds. Check the official 2026 tide forecast for Portneuf here, including detailed monthly schedules, peak times, and daily metric swings. In July, Portneuf is in its summer season, a key period for water sports, fishing, diving, and coastal navigation. Our oceanographic database syncs historical gauge records to refine harmonic coefficients for this stretch of coastline.
