Dundrum Bay and Newcastle
Bay · Salt water · in Strangford Lough and the Ards coast
A wide, shallow, south-east facing bay of clean sand backed by the Murlough dune system, with the Mourne Mountains rising immediately behind and a tidal inner bay at Dundrum.
Safety: cold water shock — can cause serious injury or death. 2 more points apply here.
FishingHQ describes what this place is. It does not say whether you may fish it: access rights, permits, licences, byelaws, closures and protected areas all apply, all differ and all change. Who to ask is below.
What you can catch here
Documented at this place, grouped by how you would be fishing, with how strongly the sources support each one. This is what has been written down, not a forecast, and being listed is never permission to fish.

What these strengths mean
- Repeatedly reported
- Several independent public accounts. Enough to say it happens more than once; not enough to call it a fishery.
- Recorded here
- At least one credible public account of this species being caught here. That is all it means.
- Places, catches and sources are counted separately
- A fish documented once at each of six marks is still documented once at each of six marks. Breadth is reported as a place count and never raises the strength, and sources are deduplicated across places so one publisher covering a whole coast counts as one.
Also associated with this ground

The ground and the water
- The ground
- A wide, shallow, south-east facing bay of clean sand backed by the Murlough dune system, with the Mourne Mountains rising immediately behind and a tidal inner bay at Dundrum.
- Exposure
- Open south-east to the Irish Sea, so an easterly blows straight in with a long fetch and produces a genuine surf on the sand.
- Depth
- Shallow and gently shelving throughout the outer bay; drying extensively inside.
- Tide and flow
- Moderate range with a strong set along the bay and a fast, narrow entrance into the inner bay at Dundrum.
Through the year
Bass in the surf through the warmer months, flatfish and ray over the clean ground, codling and whiting in the colder half.
Safety
Cold water shock — Can cause serious injury or death
UK coastal and inland water is cold enough for most of the year to trigger the involuntary gasp and the loss of swimming ability that decides most immersion deaths, and it does so within the first minute, long before hypothermia is relevant.
What reduces it: Wear a buoyancy aid rather than carry one, carry a means of calling for help on the person rather than in a bag, and plan on the assumption that an unplanned entry into the water is survivable only if somebody knows immediately.
Boat safety — Can cause serious injury or death
The lough is strewn with hundreds of rocky pladdies, many unmarked and many just covered. They show as a slick in flat calm and are invisible in the ripple that makes the fishing, and striking one at speed can hole or capsize a boat.
What reduces it: Keep to known passages, go slowly on unfamiliar water, take local knowledge of the safe routes before travelling at speed, and treat a chop as a reason to slow down rather than to press on.
Moving water and currents — Can cause injury needing treatment
A surf beach with rip currents that form in the troughs between sandbars and run seaward, and the entrance to the inner bay runs hard on both tides through a narrow channel.
What reduces it: Do not wade beyond thigh depth in surf, stay out of the inner bay entrance channel entirely, and treat a well-formed surf as evidence of rips rather than as an invitation.
Rules and access
FishingHQ does not know the current access position here. Sea angling access in Northern Ireland is governed by landowner permission, harbour and council byelaws, and fisheries and conservation measures, all of which change. Check the current position with the Department of Agriculture, Environment and Rural Affairs, the harbour or council, and the landowner before going.
Particular to this water: This ground carries conservation designations that constrain access, vehicles, bait collection and disturbance independently of any fishing rule.
Who holds the answer:
- The Department of Agriculture, Environment and Rural Affairs, for sea fisheries and marine conservation in Northern Ireland.
- The harbour authority or council, for access to the structure or the shore.
- The Northern Ireland department responsible for agriculture, environment and rural affairs, which administers sea fisheries measures and marine conservation here.
- The Loughs Agency or the Northern Ireland licensing body as applicable, for rod licensing and permits on freshwater and migratory fisheries, which differ by area.
- The Northern Ireland Environment Agency and the site management bodies, where a marine designation affects anchoring, access, collection or disturbance.
- The harbour authority at each port, for access to and fishing from harbour structures.
- The local district council and the Food Standards Agency framework, for shellfish harvesting area classification.
- The Murlough National Nature Reserve managers, for access across the dune system.
