Helensville tide times
Helensville has no predictions of its own. These times are Port Taranaki's, shifted by the difference LINZ publishes for Helensville (+1h 22m at high water, +1h 50m at low water), with heights scaled by the published ratio of 1.1.
Predictions — not for navigation
These are LINZ's astronomical predictions. Actual water levels differ with barometric pressure, wind and storm surge — commonly by 0.3 m, and by a metre or more in a severe low. Do not use this site for navigation or for any decision where being wrong is dangerous. For navigation use the official LINZ tide tables and current charts. Heights are metres above chart datum, not above sea level, and times are New Zealand local time including daylight saving.
