The Killybegs Port Tide gauge is part of the Irish National Tide Gauge Network which is a network of tide gauges located around the coast of Ireland collecting water level data as part of the development of a permanent tidal monitoring infrastructure. Parameters collected include; Station (ID), DateTime (yyyy-mm-ddThh:mm:ss), Water Level (Sea Level above Lowest Astronomical Tide [LAT], m) and Water Level (Water Level wrt Ordnance Datum Malin Head, m), sea surface temperature (celsius), and Pressure (measured variable) exerted by the atmosphere (MB). The Killybegs Port Tide gauge (54.6364, -8.3949) is owned and maintained by the Marine Institute and has been operational since July 2007. The Killybegs Port Tide gauge is part of the Irish National Tide Gauge Network which provides real-time data and freely available tidal predictions to operational activities (flood forecasting and monitoring) supporting research, recreational and navigation activities.
