Dublin (North Wall) tide times

The hero block shows the next high tide at the North Wall gauge in local Dublin time (GMT in winter, IST in summer — Irish Summer Time runs the same dates as British Summer Time). The 7-day table covers all four daily extremes. High water inside the Liffey at the Custom House lags the North Wall by 10 to 20 minutes depending on river discharge.

Mean range at the North Wall is about 3.4 metres — moderately large by Irish Sea standards. Spring tides push close to 4.3 metres around new and full moons; neaps drop near 1.7 metres. The range compresses noticeably as you move south down the east coast toward Wexford and Carnsore Point because the Irish Sea amphidrome sits roughly between Ireland and Wales — the closer you get to the amphidrome, the smaller the swing.

An amphidromic system is a tidal pattern in which the high-water line rotates around a central no-tide point — the amphidromic point. The Irish Sea has its amphidrome roughly halfway between Ireland and Wales, in the southern part of the basin. Around the amphidrome the tide range goes to zero; the further you are from it, the larger the swing. Dublin sits a fair distance from the amphidrome, so the swing here is moderately large.

Open-Meteo Marine, a gridded global ocean model. Useful for daily planning around Dublin Bay and the Liffey. For authoritative Irish tide data, the Marine Institute of Ireland and the UK Hydrographic Office Admiralty TotalTide publish predictions for the east coast including the historic Dublin North Wall and Dún Laoghaire harbour stations.

No. For piloting in or out of Dublin Port, transiting Dublin Bay, or working the rocky coast at Howth Head, the Bull Wall, or Dalkey Island use the UK Hydrographic Office Admiralty TotalTide and the Irish Marine Institute authoritative tide tables, chart products, and the latest Coast Guard notices. The bar at the Liffey mouth, the Burford Bank, and the Kish Bank further out all demand real navigational sources, not a planning tool.
