Understanding the coast of Germany
This guide explains the coast of Germany on the North Sea, the Baltic Sea; calculations, observations and product limits remain distinct.
Read a local tide
Times and heights depend on the port, datum and station timezone. Germany has North Sea and Baltic coasts, for which one table can never be assumed to apply. BSH provides tide predictions and water-level information as different products; place and datum are part of the value. Do not casually compare a North Sea port with a Baltic location. A value from another place cannot be carried to a nearby beach. Mareloa preserves the source and timestamp of its data but does not replace the national hydrographic reference.
Tidal range and coast
On the North Sea, tides, tidal flats and estuaries play a different role from the Baltic coast. A range or tide time only makes sense with its coast and reference. A national figure says nothing about access to a particular shore or beach. Tidal range is the vertical difference between low and high water. Bays, depth and coastal shape change it, so one astronomical cycle does not create the same range everywhere. Mareloa creates no national coefficient for Germany and infers no access from one number.
Prediction, model and observation
A tide table does not calculate wind. Water-level forecasts and observations can show weather effects. Retain product name, station and time when comparing them; an empty value proves neither that no difference nor no notice exists. An astronomical prediction calculates a periodic component. A model adds assumptions; an observation is a measurement at a station and time. Wind, pressure, waves and geography can change actual level. These categories remain separate and missing evidence never becomes reassuring.
Plan a coast visit
Access, bathing-water quality, nature protection and local signs are not established by a tide table. Check the responsible authority and information on site before visiting coast or tidal flats. The guide is not a navigation instruction and gives no safety assessment. Use this guide to understand provenance, not to decide an activity. Restrictions, health notices, access and signage are local and can change. Consult the competent authority and on-site information; Mareloa is not a navigation tool.
