Hymedis makes hydrometeo information freely available to end users (such as pilots, dredgers, service vessels, shore stations for shipping guidance, hydraulic engineering applications)
The HBU (Hymedis Boord Unit) is is currently not actively supported.
As an alternative, data can be consulted via our website:
Hymedis collects and distributes data from two national data sources:
Also OMS publishes weather forecasts for the Flemish coastal areas.
