5.8 · Beach · Vale of Glamorgan
Monknash Beach is a remote, scenic shingle-and-sand bay beneath low cliffs on the Vale of Glamorgan Heritage Coast, accessed via the long footpath from Monknash village/parking. Fishing is mainly surf and rough-ground work: cleanish sand patches can hold flatfish, while mixed ground and nearby kelpy edges produce rays, dogfish and the occasional bass—best fished on a rising tide with plenty of water over the foreshore.
Today · Best available
Best available: 03:00-06:00
Most likely species: Lesser Spotted Dogfish and Thornback Ray
Poor conditions. Best available around 03:00-06:00, but no window reaches the strong threshold today. Good chance of Lesser Spotted Dogfish and Thornback Ray.
Consider a backup mark if conditions do not improve.

Met Office · Open-Meteo
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.

Monknash Beach is a classic Vale of Glamorgan shore mark: a steep shingle beach backed by cliffs, with a rocky foreshore and broken ground that can fish extremely well when there’s a bit of colour and surf. It’s not a “comfort” venue, but for anglers prepared to walk and time the tide, it offers proper mixed-ground fishing and the chance of quality bass and winter codling.
Monknash Beach sits on the Heritage Coast near the village of Monknash, reached via lanes and footpaths leading down to the shore. Expect a walk and potentially steep/uneven ground, especially if you’re carrying bait, tripod and a long rod.
This is a true mixed-mark with different species showing depending on tide height, sea state and season. The rough ground and nearby broken reef lines suit predators and rock-associated fish, while the sandier patches and channels throw up flatfish.
Success at Monknash is about matching your approach to the ground and sea state—clean-range casting isn’t always the priority, but controlled presentation and tackle that can cope with rough ground is. If you’re new to the venue, start more simply and scale up only as needed.
Monknash is very tide-sensitive and can change character dramatically between low and high water. It often fishes best with some movement and a bit of colour, but you must plan around the speed of the flood and the risk of being penned in by rising water.
This is not a “flip-flops and bucket” beach when conditions are up; the cliffs, tide and underfoot terrain require proper preparation. Treat it as a serious coastal venue and have a conservative plan.
Facilities are limited and you should plan to be self-sufficient. The area is rural, and once you commit to the walk down, you won’t want to be heading back for forgotten essentials.
Fishing Monknash well is about reading the water and finding the “soft spots” among the rough—gullies, seams, and the edges of clean patches. A little time spent watching the surf and tide lines before setting up often pays back more than a longer cast.
There isn’t anything universally publicised that makes Monknash Beach an automatic no-fishing mark, but rules can change and local restrictions can apply (especially around conservation, access land, or seasonal measures). Always fish within current local guidance.
