Where this data comes from

Predictions, not observations. Real water levels depart from astronomical predictions because of barometric pressure, wind, storm surge and river discharge — routinely by 0.1–0.3 m, and by a metre or more in a storm. Not suitable for navigation. Use official tide tables and charts from your national hydrographic office.
