About Tidal data
As our reliance on the oceans as a source for economic growth increases, so too does the need for comprehensive and up-to-date marine geospatial data, so that we can make use of the marine environment in a responsible way.
Our UK tidal database contains height data from over 600 tidal gauges around the UK, making up the UK's largest network of tidal stations. The database also includes over 40 stations in the Environment Agency's UK National Tidal Network and stations from port authorities at many of the UK's primary and secondary ports.
This information can help to give a clear picture of coastal conditions around the UK to support a range of tasks, from choosing the best time to go surfing and sailing, to supporting marine infrastructure development.
