Belfast Tide Times

About Belfast Tide Times

Belfast, Northern Ireland's capital, commands a commanding position on Belfast Lough, where the River Lagan flows into a natural deep-water harbour. This industrial and cultural hub earned its reputation through shipbuilding heritage, with the iconic Titanic Museum drawing history enthusiasts worldwide. The waterfront has undergone remarkable regeneration, transforming former docklands into modern attractions and public spaces. Cathedral Quarter offers Victorian architecture and galleries, while the city's significant literary connections and political history add depth to any visit. Tidal movements here create dynamic waterfront conditions ideal for understanding coastal dynamics.. The tide predictions shown above cover 7 days of high and low tide times, updated daily using professional-grade harmonic tidal analysis. Tide heights are displayed in metres above Chart Datum (CD), the standard reference level used in marine navigation charts.

Tidal patterns at Belfast are driven by the gravitational forces of the Moon and Sun acting on the local ocean. The timing and height of each tide depends on the shape of the local coastline, water depth, and the position of celestial bodies relative to Earth. Like all coastal locations, Belfast experiences a full tidal cycle approximately every 24 hours and 50 minutes.

Spring tides — which occur at new moon and full moon — produce the largest tidal ranges at Belfast, with higher high tides and lower low tides than average. Neap tides, at the quarter moons, produce the smallest ranges. This fortnightly cycle is an important consideration for anyone planning coastal activities in the area.

How to Read the Belfast Tide Chart

The tide chart above plots predicted water height (in metres) against time for Belfast. The curved line rises to peaks (high tide) and falls to troughs (low tide). The height shown is measured above Chart Datum — a reference level set near the lowest predicted astronomical tide level for the area.

• HWHigh Water — the peak of the tide. This is when the sea is at its highest level. The exact time and height changes each day.
• LWLow Water — the trough of the tide. The sea is at its lowest level, often exposing rocks, sand, and mudflats.
• ↑Flood tide — the period when the tide is rising from low water to high water. Currents flow onshore or up estuaries during this phase.
• ↓Ebb tide — the period when the tide is falling from high water to low water. Currents flow offshore or down estuaries during this phase.

All times shown are in the local timezone for Belfast (Europe/London). Remember that tide times advance by roughly 50 minutes each day, so always check the chart for your specific visit date.
