6.3 · Beach · Gwynedd
Llandanwg Beach is a quiet, mostly sandy bay on the Cardigan Bay side of Gwynedd, with easy access from the small Llandanwg car park and a short walk over dunes/paths to the shore. Fishing is typical open-beach casting for flatfish and rays, with the best sport usually on the flooding tide when fish move in over the sand; after onshore winds and at dusk/night it can produce dogfish, rays and the odd bass, while calmer summer evenings can see mullet close in.

Where the data comes from. Weather and sea-state readings come from the Met Office and Open-Meteo forecast models, refreshed several times a day. High and low water are taken from tide-station predictions for this stretch of coast.
How the score works. Each window is scored 0–100 from the signals that most reliably move fish inshore: tide movement (a running tide carries food, so the last of the flood and first of the ebb are usually the prime spells), wind speed and direction (onshore wind stirs food into the surf — up to the point it makes fishing hard), sea state (a little wave and swell movement helps, heavy swell hurts), and weather — rain, temperature and light. Behind the headline number we score bite opportunity and comfort separately, and run a separate safety check on wind and swell. The size of the tide counts too: spring tides move more water than neaps, so the tidal range for this stretch of coast is weighed alongside the tide's direction, your target species and this mark — and unusually big springs strengthen the safety check, because the water rises faster and covers more ground.
Your target species counts. Pick a species below and the score also weights what we know about it — its season, preferred sea temperature, tide stage and sea state, and whether it feeds by day or night.
The rating is guidance, not a guarantee — conditions change fast on the coast, so always judge the sea in front of you before you fish.

Strong spring tides — the sea rises faster and reaches further up the shore than usual, so allow extra margin on access routes and cut-off points.
The fishing rating combines opportunity and comfort. Always check local sea conditions; the safety check is guidance, not a guarantee.
Spring vs neap tides. Spring tides have a larger difference between high and low water, so more water moves on each tide — usually stronger flow that stirs up food and gets fish feeding. Neap tides have a smaller range and generally gentler movement. The range here is compared with what is normal for this stretch of coast, and the cycle swings between springs and neaps roughly every week, following the moon.
Big spring tides: the water rises faster and covers more ground than usual — double-check access routes and cut-off points before you fish.

Llandanwg Beach is a classic Cardigan Bay surf mark tucked below the dunes and the small church at Llandanwg, with a long sweep of sand that can fish well when there’s a bit of colour in the water. It’s generally a “searching” beach rather than a guaranteed bag-up venue, but it’s a great option for bass and flounder with chances of other species when conditions line up.
The mark is the sandy shore at Llandanwg, just south of Harlech, accessed via the dunes near the church and the small beach parking/approach. It’s a straightforward walk onto sand, but the beach is remote-feeling and conditions can change quickly.
This is primarily a flatfish and bass beach, with other common UK surf species possible depending on season, surf state, and bait choice. In settled summer conditions it can be scratchy in daylight, but it often improves around dusk/dawn or with a light surf.
Llandanwg suits standard surf tactics: keep rigs simple, match lead weight to surf, and be ready to adapt as the tide pushes in. Because the ground is mainly sand, you can fish cleanly with most beach rigs, but always stay alert for any patches of rough or snaggy debris after storms.
This beach can fish across the tide, but it’s often the flooding tide that brings fish into range and concentrates feeding along the forming surf line. Like many open sand beaches, it responds well to a bit of swell and a gentle onshore push, and can be slow in flat-calm, gin-clear conditions.
Llandanwg is an open, natural beach with fast-changing coastal conditions and limited immediate shelter. The biggest hazards are tide cut-off, soft sand, and the energy of surf and swell when weather is up.
Facilities are limited at the mark itself, so it’s best treated as a self-sufficient session. Nearby Harlech offers broader amenities if you need bait, food, or shelter.
This is a “read the beach” venue where small features make a big difference, and a short move can turn a blank into a few fish. Spend time looking for structure: gutters, seams, and areas where surf is breaking unevenly.
I’m not aware of a blanket, permanent ban on recreational sea angling at Llandanwg Beach, but local restrictions can apply in coastal areas (especially around seasonal dog controls, protected habitats, or temporary safety notices). Always follow on-site signage and any local bylaws, and double-check if you plan to fish near sensitive dune systems.
