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 Port Isaac Tide Forecast
Situated along the coastline of United Kingdom (51.57° N, 2.70° W), Port Isaac 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 7.1m and spring tides reaching up to 10.4m. Tidal range exceeding 5 metres ranks this location among the world's most extreme — a rare geographic phenomenon. Two daily tidal cycles create two current peaks per day, valued by anglers who leverage stronger flow during tidal changes. Its geographic position creates unique interactions between oceanic swell and local tidal currents. The 2026 tidal schedule for Port Isaac provides a full-year calendar of high and low waters alongside predicted sea levels. In September, Port Isaac is in its autumn season, a key period for water sports, fishing, diving, and coastal navigation. Predictive output is continuously benchmarked against time series recorded by regional coastal reference stations.
