Sudbrook Tide Times

About Sudbrook Tide Times

The Severn Estuary's dramatic tidal range makes Sudbrook a compelling destination for tide watchers and maritime enthusiasts. This Welsh settlement on the Monmouth side of the estuary experiences some of Britain's most extreme tidal movements, with the waters transforming the landscape twice daily. The area's industrial heritage reflects generations of interaction with these powerful tides—historically exploited for mills and modern energy projects. Mudflats and salt marshes dominate the shoreline, creating a distinctive habitat that shifts dramatically between high and low water. Sudbrook offers an authentic glimpse into how communities have adapted to one of Europe's most challenging tidal environments.. 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 Sudbrook 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, Sudbrook 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 Sudbrook, 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 Sudbrook Tide Chart

The tide chart above plots predicted water height (in metres) against time for Sudbrook. 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 Sudbrook (Europe/London). Remember that tide times advance by roughly 50 minutes each day, so always check the chart for your specific visit date.
