These are computer predictions and can be wrong, especially close to the shore, in rivers and in strong winds or unusual air pressure. Check the official tide tables and forecast for the area before you rely on them. Not for navigation.

Harmonic predictions from the FES2022 tide atlas: the astronomical tide, without the effect of wind and air pressure. Heights are in metres above chart datum (lowest astronomical tide).
