Forecast, observation and tide

A model forecast estimates a future situation; it is not an on-site measurement. An observation describes a reading at a particular place and time. A tide table answers a different question and cannot be derived from wave height. Missing information is not replaced with invented values.

Before a beach outing

For swimming, follow the signs, flags and instructions of lifeguards on site. A calm-looking sea or forecast value is not enough to determine that swimming is permitted. Prepare water sports with the organiser.

Read Practical information and information from your beach municipality. Marine data publication will only be considered after checking sources, licences and terms of use.
