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 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 October, Portneuf is in its autumn 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.
