UK Tide Gauge Network
The UK National Tide Gauge Network was set up as a result of severe flooding along the east coast of England in 1953.
It forms part of the UK Coastal Flood Forecasting (UKCFF) service. UKCFF is a partnership formed by the Environment Agency (EA), Scottish Environment Protection Agency (SEPA) Department for Agriculture and Rivers Agency Northern Ireland (RANI) and Natural Resources Wales (NRW). Through the partnership the authorities commission and deliver the capabilities in monitoring and forecasting of coastal conditions that underpin coastal flood forecasting and flood risk modelling throughout the UK.
The network includes 43 gauges as illustrated in the map below, most of which are related through the national levelling network to Ordnance Datum Newlyn. The whole network is owned by the Environment Agency who operates the network on behalf of the UKCFF partners. Data are collected, processed and archived centrally to provide long time series (please see the individual tide gauge data availability) of reliable and accurate sea levels.
BODC has a special responsibility for the remote monitoring and retrieval of sea level data from the network. Daily checks are kept on the performance of the gauges and the data are downloaded weekly. These are then routinely processed and quality controlled prior to being made available for scientific use.
Data availability
BODC make quality-controlled NTSLF data series available online as soon as they are processed. We aim to have each month's data files online four weeks from the end of the month.
- Processed data from 1915 to August 2024 are available free of charge
- Download annual and monthly files - primary and secondary channels
- Download delayed-mode processed data from all data channels
- Processed data for the last month is available by request – there is a fee for this service
- Download (and view plots of) near real-time unprocessed data covering the month to today
- Download NTSLF Annual Reports
National Tidal & Sea Level Facility (NTSLF)
The UK Tide Gauge Network forms part of the National Tidal & Sea Level Facility (NTSLF) which is hosted by the National Oceanography Centre (NOC) and is a consortium consisting of
- NOC science groups
- British Oceanographic Data Centre (BODC)
- UK Tide Gauge Inspectorate
- NOC Applications Group
- Environment Agency
- Department for Environment, Food and Rural Affairs (defra)
- British Isles GPS archive Facility (BIGF)
Monthly and annual values of sea level are held by the Permanent Service for Mean Sea Level (PSMSL) and can be obtained from their web pages. Tidal predictions and tide tables are handled by the NOC Applications Group. Visit their web pages for further information.
