Important: TideAtlas provides mathematical, non-official model predictions. Wind, air pressure, waves, and river discharge are not included. Heights refer to the model level and not automatically to LAT, SKN, NAP, or an official chart datum. Not for navigation; use official nautical publications and current observations for safety-critical decisions.
