High tide occurs approximately 10:31 after the Moon passes over the local meridian of Pernem.
Tidal predictions and solunar activity are mathematically estimated for recreational and tide watch calibration purposes only. This constant-based method is designed for semidiurnal tidal regimes (two high tides a day). Regions with diurnal or mixed tides will experience significant deviations. During lunar quarters (First and Third Quarter), natural variations may shift times by 1.5 to 2 hours compared to official tables.Strictly not for maritime navigation or safety-critical planning.
