Summary
Seaton Beach sits on Cornwall’s south coast between Downderry and Looe, where the River Seaton meets a broad sweep of shingle and sand. It’s a versatile, easy-access mark that fishes across the seasons, with mixed ground, a productive river mouth, and rocky fringes offering varied sport. Ideal for bass in the right surf and rays over the sandy patches, it’s also a comfortable venue with good facilities close at hand.
Location and Access
Set in the Seaton Valley, the beach is immediately beside the village and Seaton Country Park, with simple, level access from the promenade. There is pay-and-display parking by the beach and further spaces within the country park; the coast road and the B3247 make it straightforward from both Looe and Plymouth directions.
- Drive via the B3247 down Seaton Valley; the beach car park sits beside the bridge over the River Seaton and the green.
- Level promenade access with ramps; the beach itself is shingle-over-sand, which is firm but tiring to walk with heavy gear.
- You can roam east towards Downderry over mixed ground and low-tide rock, or stay front-and-centre for easier clean-ish ground.
- Public transport runs along the coastal route; a bus stop is a short stroll from the beach.
- For sat nav, search for “Seaton Beach, Cornwall” or “Seaton Country Park” rather than relying on a single postcode.
Seasons
This is a classic mixed-ground south-coast venue; expect bass and flatties around the river mouth, rays on the sand, and summer pelagics from the rocky ends. Seasonality is marked, with night fishing often out-fishing daylight on settled seas.
- Spring (Mar–May):
- Bass (schoolies and occasional larger fish, especially after a blow)
- Flounder in and around the river mouth
- Plaice (occasional) on cleaner sand, garfish late spring
- Smoothhound appearances from late May when peelers are about
- Summer (Jun–Aug):
- Bass (dawn/dusk and into darkness)
- Mackerel and garfish; scad at dusk
- Small-eyed ray on the sandy runs; dogfish common
- Black bream (occasional) over rougher ground; wrasse and pollack from rocky fringes
- Gurnards on worm or fish baits over sand
- Autumn (Sep–Nov):
- Bass peak period, especially in surf or coloured water
- Small-eyed ray and huss on bigger baits at night
- Sole on calm, dark nights; whiting begin to show
- Red mullet (occasional) on small worm baits after dark
- Winter (Dec–Feb):
- Whiting, pouting, dogfish on most tides
- Huss and conger from rough patches after dark
- Flounder near the river on settled days
Methods
The beach rewards a mix of beachcasting for rays/flatfish and more mobile lure or float tactics for bass and summer species. Match your approach to the ground in front of you: clean sand for rays and soles; mixed patches for bass and huss; rock fringes for wrasse and pelagics.
- Bottom fishing:
- Rigs: pulley pennel (3/0–4/0) for bass/rays; up-and-over or long dropper for distance with sandeel; two/three-hook flappers (size 2–1) for flatties and whiting.
- Leads: 4–5 oz grip leads suit most tides; step up on spring floods or in surf.
- Baits: peeler crab (top for bass/smoothhound), lug/rag cocktails for flats and bass, sandeel and bluey/mackerel strip for rays, squid or squid/fish cocktails for huss and dogs. Use bait elastic to beat crab attention.
- Lure and float tactics:
- Surface and shallow divers or soft-plastic sandeels at first/last light along the surf line for bass.
- Metals for mackerel/scad when birds show; floats with slivers of mackerel for garfish around the rocky ends.
- LRF/HRF around boulders and groynes for wrasse, pollack, blennies, and scad at dusk.
- Tackle notes:
- 12–13 ft beachcasters with a 60 lb shockleader for clipped-down distance work.
- A sturdy tripod is essential on steep shingle; long-nosed pliers and a headtorch for night sessions.
- Scale down to lighter gear on calm, clear nights for soles and breamy odds and ends.
Tides and Conditions
Like most south-coast mixed beaches, Seaton is driven by tide and sea state. A mild onshore push or coloured water from the river can transform an otherwise quiet day.
- Tide states:
- Flood into dusk and the first hours of darkness are prime for bass and rays.
- The first two hours of the ebb around the river mouth can be excellent for bass and flounder as food washes out.
- Springs stir more movement and often out-fish neaps for bass; neaps can suit sole and rays in settled seas.
- Sea conditions:
- A modest southerly-on shore swell with a touch of colour is perfect for bass; avoid heavy weed after big blows.
- Clear, calm days favour garfish, mackerel, and lure work.
- Night fishing consistently improves results for rays, sole, huss, and better bass.
- Seasonality:
- Late spring through autumn is the most consistent; winter still produces whiting, dogs, and the odd ray in settled spells.
Safety
This is a friendly, family beach with a promenade, but anglers should respect the power of surf on steep shingle and the pull near the river mouth. The rocky ends get slippery with weed, and some ledges can be cut off on big tides.
- Shingle banks can develop steep faces; beware heavy backwash in swell and avoid wading.
- The River Seaton outflow creates strong lateral currents and soft patches—keep clear in spate flows.
- Weed-covered rocks are treacherous; use studded boots and never turn your back on the sea.
- On spring highs with a southerly swell, waves can reach the promenade—set up well back.
- If you explore towards Downderry at low water, note your exits to avoid being cut off by a fast-flooding tide.
- Carry a headtorch, tell someone your plan, and consider a lifejacket if fishing from rocky areas.
- Access is generally good: ramped promenade and nearby parking; the shingle itself is challenging for wheelchairs and those with limited mobility.
Facilities
Seaton is well served for a fishing beach, with loos, café options, and level access. Tackle supplies are a short drive away.
- Toilets: public toilets by the beach car park (seasonal opening hours).
- Food & drink: Seaton Beach Café by the promenade; additional pubs/cafés in Seaton and nearby Downderry.
- Parking: pay-and-display next to the beach and further spaces in Seaton Country Park.
- Tackle/bait: head to Looe (multiple angling shops) or Liskeard for fresh bait and tackle.
- Phone signal: generally fair on the promenade; can dip in the valley behind the beach.
Tips
Local patterns repeat here: find the right line of colour, keep mobile, and match rigs to ground. The venue shines when you read the beach at low water and return on a pushing tide.
- Scout at low tide to map sandy tongues versus rough patches; drop rigs on sand lanes for rays and soles.
- Work the colour seam where river water meets the sea for bass—especially on the first push of the flood or early ebb.
- In summer, crabs are relentless: bind baits tight, use tougher options (squid/razor), or recast every 10–15 minutes.
- Clip-down rigs and aerodynamic leads noticeably improve distance and presentation on breezy days.
- Watch for bird activity in the bay; when they’re working, have a metal or float rod ready for mackerel/gar.
- Keep light and noise to a minimum on calm nights—stealth pays dividends with in-close bass and sole.
- Carry spare leads and abrasion-resistant snoods; the mixed ground eats gear on a big sweep.
Regulations
Rod-and-line sea angling is permitted from Seaton Beach. The coastline sits within the Whitsand & Looe Bay Marine Conservation Zone, which does not prohibit shore angling, but do treat sensitive habitats with care.
- Bass regulations (England): seasons, daily bag limits, and a 42 cm minimum size apply and can change—check the latest from the MMO/DEFRA before your trip.
- Observe UK minimum sizes for retained species (e.g., flatfish, rays where applicable); when in doubt, return fish.
- Many local anglers practice catch-and-release for large wrasse from rocky ground to protect resident stocks.
- During peak summer days, RNLI may flag designated bathing zones; avoid casting within flagged swimming areas and follow lifeguard requests.
- If using a drop net from any structure or fishing near boats, give commercial and leisure traffic clear priority and ample space.
- Always take litter and line home; MCZ or council byelaws may be updated—check Cornwall IFCA and council notices on-site.
