Lunitidal Interval (Establishment of the Port)
04:40 hours

High tide occurs approximately 04:40 after the Moon passes over the local meridian of Lyttelton / Christchurch.

Reliability: Official Data
Coordinates: -43.6°, 172.7167°
Important Safety Notice:

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.
