Summary
Porthpean Beach (St Austell Bay) is a sheltered south-coast Cornish beach backed by low cliffs and flanked by rocky headlands. It’s a friendly, mixed-ground mark that rewards thoughtful tactics with bass, wrasse, summer pelagics and the odd ray over sand. Quiet evenings and autumn nights can be especially productive.
Location and Access
Set just south of St Austell and east of Charlestown, Porthpean is easy to reach and fishes well without a long hike. The central beach is clean sand, with accessible mixed and rough ground at either end for more species variety.
- Drive via St Austell towards Porthpean; follow brown beach signs. Nearest sat‑nav postcode: PL26 6AU (for the beach car park).
- Pay-and-display car park above the beach; short walk down a sloped lane/steps. Spaces can be tight on hot weekends—arrive early or fish off-peak.
- Terrain: clean sand in the middle; boulders, kelp and reef fingers at both ends. Good mixed options allow you to switch tactics with the tide.
- No long coastpath yomp needed; tackle trolleys are workable, but steps make it awkward for very heavy loads.
Seasons
This mark holds a reliable spread of south-coast species. Fish the clean sand for flatfish and rays, and the rocks for wrasse and pollack, with summer shoals moving through the bay.
- Common targets (seasonal):
- Bass (spring–autumn, peak May–October; also after blows)
- Ballan and corkwing wrasse (late spring–early autumn around the rocks)
- Mackerel and garfish (summer, best at dawn/dusk and on clear, calm water)
- Scad/horse mackerel (summer/autumn nights under headlamps)
- Pollack (year-round around rough ground; best in lower light)
- Lesser-spotted dogfish (most months; strong at night)
- Whiting and poor cod/pout (late autumn–winter nights)
- Flounder and dab, with the odd plaice (spring and autumn over the sand)
- Thornback ray (late spring–autumn nights, occasional)
- Smoothhound (late May–September on crab, occasional)
- Red/grey gurnard (summer over clean patches)
- Occasional visitors:
- Black bream in warm summers (mixed/clean patches)
- Conger from the rougher margins at night
- Cuttlefish/squid in some autumns on calm, clear nights
Methods
Porthpean suits light-to-medium shore gear with a mix of ledgering over sand and lure/float work around the rocks. Keep mobile, read the ground lines, and tailor rig length to water clarity.
- General beach tactics:
- Two-hook flapper (size 2–1/0) with ragworm, lug, or mackerel/squid strips for flatties, gurnard, whiting and dogs.
- Pulley or pulley dropper (3/0–4/0) with sandeel, bluey or mackerel for thornbacks; peeler or soft crab for smoothhounds.
- Long flowing trace (3–5 ft, 1/0–2/0) with sandeel, razorfish, crab or lug for roaming bass along the surf line.
- Rock-edge tactics (either end):
- Float fish ragworm, prawn or hardback crab for wrasse; small slivers for gar/mackerel.
- Lures: 20–40 g metals for mackerel/scad; weedless soft plastics (10–20 g) and small paddletails for bass/pollack; surface lures at first/last light on calm days.
- LRF/micro-jigging after dark for scad and small pollack (match size 6–10 hooks and isome/scented worms).
- Leads: 2–4 oz usually ample in the bay; grip leads only in lively surf. Use a weak link/rotten bottom near reef edges to save gear.
Tides and Conditions
Sheltered by the bay, Porthpean often fishes best around high water, with clarity dictating whether you fish baits or lures. Night tides transform the venue for rays, dogs and winter whiting.
- Tide state:
- Flood to high water and the first hour of the ebb are the prime windows on the sand.
- Over neaps, wrasse and lure fishing around the ends can be excellent; springs can push bass/rays tighter in.
- Sea and wind:
- Light onshore S–SW giving a gentle lift stirs bass without making it unfishable.
- Clear, calm conditions suit lures, gar and mackerel; a slight chop helps confidence for bass.
- Time of day/season:
- Dawn and dusk in summer for pelagics and bass; after-dark for scad and rays.
- Winter evenings for whiting, pout and dogs on small fish baits.
- Water clarity and weed:
- After a blow, colour improves bass prospects on bait; persistent kelp/weed strands often sit near the reef edges—adjust casting angles to avoid them.
Safety
This is a user-heavy family beach in season with rocky, weeded ends—fish thoughtfully and keep your footing sure. Treat the headland margins with the same respect you would a rock mark.
- Crowds and water users:
- Expect swimmers, paddleboarders and sailing dinghies; avoid casting anywhere near people and give priority to lifeguarded swim zones when operating.
- Ground hazards:
- Slippery weeded rocks and boulders at both ends; wear grippy boots and consider a lifejacket if venturing onto the rocks.
- Use a rotten-bottom link over mixed/rough ground to reduce losses.
- Tide and cut-off risk:
- On big springs, the tide can push tight to the cliff toes near the ends—plan an exit and avoid being cut off.
- Access and mobility:
- Short but stepped approach from the car park; manageable for most, but not ideal for wheelchairs or very heavy barrows.
- Night fishing:
- Carry a headlamp plus spare light, keep to known paths, and fish with a partner if possible.
Facilities
Porthpean is well-served for a small beach, with amenities close by and larger services in St Austell. Expect seasonal openings to vary.
- Pay-and-display car park adjacent to the beach (seasonal charges).
- Public toilets near the car park (typically open in season).
- Beach café/kiosk in summer; Porthpean Sailing Club operates at the eastern end (watch for dinghies/launching).
- Pubs, food and additional parking in nearby Charlestown; supermarkets and fuel in St Austell.
- Tackle and bait available in St Austell and Mevagissey (check opening hours, especially Sundays).
- Mobile signal generally fair, with occasional dips close to the cliffs.
Tips
Little adjustments here make a big difference—fish the right ground line for your target and time your session to dodge the beach crowds.
- In summer, fish early or late to avoid swimmers; after-dark sessions are markedly better for rays, scad and dogs.
- Find the sand–reef edge and drop a pulley bait just beyond it for thornbacks; too far and you’ll hit weed, too short and you’ll miss them.
- Bass often patrol knee-to-waist deep water—don’t always blast it; try a long flowing trace into the first gutter.
- For wrasse, bring sacrificial end tackle or use weedless hooks and crabs/prawn under a float set close to bottom.
- When mackerel are picky, downsize to slim 20–28 g metals or a two-feather trace rather than full strings.
- Autumn nights: LRF with size 8–10 hooks and isome can be nonstop for scad—great fun and useful bait gatherers.
- After onshore blows, razorfish and sandeel make killer fresh baits if you can source them locally.
Regulations
Fishing is generally permitted from Porthpean Beach, but normal national and local byelaws apply. Always check the latest Cornwall IFCA and MMO notices before your trip.
- Bass (recreational): Minimum size 42 cm. As of current rules, a limited bag season typically applies (commonly two fish per angler per day during the open months) with catch-and-release only in closed months; confirm the exact dates and limits for the year of your visit.
- Minimum conservation reference sizes (MCRS): Observe Cornwall IFCA sizes for species such as wrasse, bream, gurnard, flatfish, rays, etc. Return undersized fish promptly.
- Crustaceans: Berried or v‑notched lobsters and crawfish must be returned; local limits and sizes apply to edible crab/velvet/swimmer crabs. Do not remove undersized shore crabs from nursery pools.
- Nets and bait collection: Fixed nets and certain gears may be restricted near bathing beaches and in specific seasons—check IFCA byelaws. Collect bait responsibly and avoid damaging seagrass or protected habitats.
- Beach management: Do not fish within designated lifeguarded swim zones when flags are up, and obey any temporary local signage or event restrictions.
- Protected species: If you encounter shad, tope, angel shark or other protected species, release immediately and report if required.
