🎣 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 PORTLAND Tide Forecast
PORTLAND is located at 43.66° N, 70.24° W on the coast of United States, in the northern hemisphere. Its tidal pattern is semi-diurnal (two high and two low tides per day), with a mean tidal range of 2.6m and spring tides reaching up to 2.9m. The 1.5–3 metre tidal range significantly affects navigation for small vessels, which should consult the tide table before crossing shallow bars. Two daily tidal cycles create two current peaks per day, valued by anglers who leverage stronger flow during tidal changes. Coastal water salinity varies with rainy seasons, creating gradients that influence the distribution of marine species. The 2026 tidal bulletin for PORTLAND delivers a thorough schedule of sea level swings with hourly marks for the entire year. In September, PORTLAND 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.
