6.3 · Beach · Ceredigion
Long, open sandy surf beach on the south side of the Dyfi (Dovey) estuary, backed by dunes and reached via the Ynyslas National Nature Reserve car park with an easy walk onto the sand. Fishing is classic west Wales surf work: best on a flooding tide into dusk/dark with deeper gutters and the estuary mouth holding most interest; expect mixed flatfish and dogs, with rays and bass possible when conditions and bait are right.
Today · Best available
Best available: 18:00-21:00 around the falling tide
Most likely species: Flounder and Plaice
Fair conditions. Best available around 18:00-21:00 around the falling tide, but no window reaches the strong threshold today. Good chance of Flounder and Plaice.
Fishable, but pick your timing carefully.

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.

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.

Ynyslas Beach is a classic open surf mark on the south side of the Dyfi Estuary, facing into Cardigan Bay and renowned for clean sand, strong tides and big-water conditions. It can fish very well for mixed species depending on season, but it’s a place where reading the sea and choosing the right state of tide makes a huge difference.
Ynyslas sits at the mouth of the Dyfi (Dovey) Estuary near Borth, with access via the Ynyslas National Nature Reserve area and beach paths through the dunes. Access is generally straightforward, but the walk can be longer depending on where you park and how far along the beach you want to fish.
Ynyslas is primarily a surf venue with seasonal variety, and it’s at its best when the beach has defined gullies and a bit of colour in the water. Expect typical Cardigan Bay sand-beach species, with occasional better fish when conditions line up.
This is a venue where simple, robust surf tactics work, but fine-tuning your approach to the day’s surf and the shape of the beach pays dividends. Most anglers will do best by targeting gutters at mid-tide and keeping rigs fishing effectively in a moving sea.
Ynyslas is strongly influenced by tide and swell, and the beach profile can change after storms, creating (or removing) the gullies that fish patrol. It can fish in both clean and coloured water, but the ‘right’ level of surf is key—too flat can be slow, too wild can be unfishable.
This is an exposed beach environment with fast-changing weather and sea state, and the Dyfi estuary nearby adds extra hazards if you stray toward strong currents or soft ground. Take the venue seriously in big swell or strong winds, and don’t underestimate the effort of a long walk back with gear.
Facilities depend on where you base yourself around Ynyslas and the wider Borth/Ynyslas area, with a mix of seasonal and local amenities rather than a ‘purpose-built’ angling complex. Plan self-sufficiently, especially for early/late sessions.
Ynyslas rewards anglers who treat it as a ‘feature-finding’ beach rather than a fixed-spot venue. Spend a few minutes watching the water and you’ll often spot the darker lanes of deeper water and the white water lines that show the bars.
Ynyslas lies within a sensitive coastal/dune environment (part of the Ynyslas National Nature Reserve), so access routes and seasonal restrictions can apply even when angling itself is generally permitted. I’m not aware of a blanket ban on shore angling across the whole beach, but you should treat local signage as definitive.
