Part of Ireland’s ocean observation system
INTGN links coastal data with offshore and shoreline measurements. Together, these observations show how ocean conditions develop and affect the coast.

Coastal sea level monitoring
INTGN has 19 tide gauge stations along the Irish coast. Every station measures sea level, tidal cycles, and harmonic behaviour. Some stations also measure sea temperature and atmospheric pressure.
High-resolution datasets
- continuous time series
- high temporal resolution
- near real-time availability
How tide gauge data is used
INTGN observations support scientific work, coastal planning, and public understanding of changing conditions.
Research and modelling
High-frequency observations support tidal analysis, modelling, coastal process research, and long-term sea level monitoring.
Forecasting and coastal planning
Sea level and tidal information supports storm surge and flood forecasting. It also helps people plan beach trips, boating, and fishing around changing conditions.
Coastal reporting and stories
The observations provide context for coastal flooding, storm surge events, extreme tides, weather impacts, community risks, and climate and sea level stories.
Global sea level observation (GLOSS)
- stations at Howth Harbour and Union Hall
- multiple sensors at the stations
- GNSS systems that measure land movement and help distinguish sea level rise from vertical land motion
Access the data
INTGN data includes real-time sea level measurements, tidal predictions, and downloadable datasets.
