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 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 July, PORTLAND 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.
