🎣 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 Penrhyn Tide Forecast
The coordinates for Penrhyn (-8.98° S, 158.05° W) place this stretch of Cook Islands's coast in the southern hemisphere. Its tidal pattern is semi-diurnal (two high and two low tides per day), with a mean tidal range of 0.2m and spring tides reaching up to 0.3m. The small tides here make this coast particularly suitable for sailing and coastal touring by kayak. Mariners in semi-diurnal areas benefit from two high-water windows each day to cross shallow bars or enter marinas. Coastal water salinity varies with rainy seasons, creating gradients that influence the distribution of marine species. The 2026 tidal schedule for Penrhyn provides a full-year calendar of high and low waters alongside predicted sea levels. In September, Penrhyn is in its spring season, a key period for water sports, fishing, diving, and coastal navigation. MaréAgora calculations use harmonic decomposition calibrated via satellite altimetry and local gauges to ensure high accuracy.
