High tide occurs approximately 04:10 after the Moon passes over the local meridian of João Pessoa (Cabo Branco).
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.
