6.0 · Rocks · Conwy
Rhos-on-Sea is a very accessible mixed shore mark on the Conwy coast, centred on the promenade and Rhos Point where a rough reef of boulders/bedrock meets sand. You can fish from the rocks at mid to high water or cast from the adjacent beach for flatfish; the ground is snaggy close in with gullies and kelp, so simple running rigs and rotten-bottom leads help. It’s a popular, often clear-water venue that fishes best on a bit of swell or colour, with dusk tides generally producing more takes.
Today · Best available
Best available: 18:00-21:00
Most likely species: Pollack and Flounder
Poor conditions. Best available around 18:00-21:00, but no window reaches the strong threshold today. Good chance of Pollack and Flounder.
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.

Rhos-on-Sea is a classic North Wales mixed shore mark combining promenade rock patches, short rock groynes and adjacent clean sand, giving you options in both calm and rougher weather. It’s best approached as a “feature-hunting” venue: fish the rough close in for wrasse and codling in winter, then slide onto the cleaner ground for flats and bass when conditions suit.
Rhos-on-Sea sits on the Conwy coast just east of Llandudno, fronted by a long promenade with beaches and rocky sections breaking up the sand. Access is straightforward, with most anglers approaching from the seafront and walking to whichever patches of rock/weed or cleaner sand look fishiest on the day.
Expect the usual Conwy-bay mix, with the best fish often coming when you match the ground to the target species (rough for wrasse/codling, clean for flats). Seasonal changes matter here: warm months favour wrasse and bass, while colder months can bring codling and a general run of whiting-sized fish.
This is a venue where you’ll do well by carrying two approaches: one for the rocks and one for the sand. Keep rigs simple and robust—weed and snags are common on the rough, while the sand responds well to clean-presented baits.
Rhos-on-Sea fishes differently across the tide because the productive features (weed edges, gutters, and rock seams) either flood quickly or become inaccessible at low water. A bit of movement and a touch of colour are often your friend, but strong swell can make the rocks hazardous.
Most of the mark is easy to reach, but the fishing itself ranges from straightforward beach casting to genuinely slippery rock work. Treat the weeded ledges with respect—this coastline can go from “fine” to “dangerous” quickly when swell increases.
Rhos-on-Sea is a convenient “fish and go” venue with typical seaside amenities close by. That makes it ideal for short sessions, family-friendly trips (non-fishing companions), and quick after-work tides.
You’ll catch more by fishing the right micro-feature than by sitting in one place all session. On this coast, a small gully, a kelp edge or a slightly deeper run can be the difference between blanks and steady bites.
I’m not aware of a blanket ban specifically at Rhos-on-Sea, but shore rules can change and local restrictions may apply in certain areas (especially near bathing zones, outfalls, or managed seafront sections). Always follow local signage and any instructions from coastal staff.
