Abercastle Bay

Abercastle Bay is a small, sheltered Pembrokeshire cove that can fish well for mixed species when the swell is down and the water has a bit of movement. It’s not a “numbers” venue like some open surf beaches, but it’s a reliable, enjoyable rock-and-bay mark that suits light to medium sea angling.

• Best thought of as a sheltered bay/estuary-style cove with rocky structure, kelp and broken ground
• Often a good option when the open coast is too rough, but it can become unfishable in heavy swell or strong onshore wind
• Expect a varied catch rather than one single “headline” species every session

Abercastle Bay sits on the north Pembrokeshire coast, with access generally via the small harbour/boat slip area and paths around the cove. Approaches are straightforward compared with many cliff marks, but you’re still fishing rock and weed in places.

• Parking is typically in or near the village/harbour area; walk-on access to the bay and harbour walls is usually short
• Most anglers fish from the harbour area, the rocks around the bay, or from slightly more open-water edges when conditions allow
• Access can be restricted by tide on lower rocks and by wave wash on exposed corners—have alternative spots in mind within the bay

Abercastle is a classic “mixed ground” venue where what you catch is strongly linked to tide height, water clarity and the amount of kelp/weed present. In settled summer it can be relatively clear; after a bit of sea it often fishes better for predators.

• Wrasse (ballan and corkwing) around kelp and boulders in the warmer months
• Pollack and occasional coalfish around deeper rock edges and any tide run
• Mackerel in season when shoals come close (often best from more open-water positions)
• Bass can show, especially with a bit of colour in the water and on bigger tides
• Flounder/dab and other flatfish are possible on sandier patches and the inner bay, particularly with gentle conditions
• Conger and small sharks are possible on rougher ground after dark in suitable conditions (expect snags)

A flexible approach works best here: fish clean patches with bait when you can find them, and switch to lures or float fishing around the rougher kelp. Tackle choice is a balance between casting distance and having enough control to steer fish away from weed.

• Spinning/soft plastics: work sandeel-style lures, shads or metal lures along rock edges for pollack/bass; retrieve speeds vary with clarity and tide
• Float fishing: a highly effective method for wrasse and pollack in the bay—present ragworm, crab or small fish baits close to kelp lines and boulders
• Light/medium bottom fishing: use simple running ledger or pulley-style rigs depending on how snaggy your chosen spot is; keep traces robust if wrasse are the target
• Baits: ragworm, lugworm, peeler crab and fish baits all have a place; crab is especially useful when wrasse/bass are about
• Practical tip: bring spare rigs and leads—kelp and broken ground will claim tackle if you fish too “tight” to the rough

Abercastle tends to fish best with some movement and a little colour in the water, but not with heavy swell pushing right into the bay. You can usually find a fishable corner on moderate tides, but the most productive periods often align with stronger flows.

• Tide: mid to high water often opens up access and depth over the rocks; low water can expose weed and make some areas awkward
• Sea state: a slight swell and “stirred” water can improve bass/pollack chances; too much swell makes it dangerous and can kill presentation
• Wind: offshore or light cross winds are generally favourable; strong onshore winds can funnel swell into the cove and make ledges unsafe
• Clarity: very clear water can make fish cautious—fish dawn/dusk, scale down baits, or switch to more natural lure colours
• Time: early morning and evening can be standout; after-dark fishing can be rewarding but requires careful mark knowledge

This is a scenic but still potentially hazardous rock-and-harbour venue where conditions can change quickly, especially with swell. Treat it as a proper coastal mark: assess wave action, footing and escape routes before committing to a platform.

• Slippery kelp-covered rocks are common—wear appropriate footwear with good grip; consider a wading staff for balance
• Swell can surge into the bay and around corners even when it looks “manageable”—avoid low ledges if there’s any wash
• Check your exit route on a rising tide; don’t get cut off from the harbour/path
• Night fishing increases risk significantly due to uneven ground and wave wash—fish with a partner if possible
• Accessibility: the harbour area is generally easier than more uneven rocks; those with limited mobility may prefer fishing from more stable harbour-side positions (where permitted and safe)

Facilities are limited but you’re close to a small coastal community, so basic amenities are usually within a short walk/drive. Plan as a semi-remote session: bring what you need, especially if fishing early/late.

• Nearby parking in the village/harbour area (availability can vary)
• Limited shelter from weather; exposed edges can be windy even when the bay looks calm
• Mobile signal can be variable on parts of the Pembrokeshire coast—don’t rely on it for safety
• Take a headtorch for low-light sessions and a spare light in case of failure

Abercastle rewards anglers who keep moving and match tactics to the ground. Spend time watching the water—baitfish flicking, gull activity, and tide lines in the bay will tell you where to start.

• Start with a short “prospecting” session: a few casts with a lure to locate pollack/bass, then switch to float tactics if wrasse are dominant
• Fish the kelp edges rather than ploughing straight into the thickest weed; you’ll lose less gear and hook more fish cleanly
• If crabs are stripping baits, toughen up with crab/fish baits or shorten the time between checks
• Carry a variety of lead sizes: too light and you’ll drift into snags; too heavy and you’ll wedge into cracks
• Be considerate around the slip/harbour activity—give way to boats and avoid blocking paths or access points

I’m not aware of a blanket, permanent ban on recreational sea angling at Abercastle Bay itself, but local restrictions can apply around harbours, slipways, and within protected or managed coastal areas. Rules can also change seasonally.

• Check on-site signage around the harbour, slipway and paths for any “no fishing” zones, safety exclusions, or harbour byelaws
• Pembrokeshire has areas with additional protections (e.g., sensitive habitats/management measures); verify whether any specific angling restrictions apply at the time of your visit via official sources
• If targeting bass or any other regulated species, follow current national rules on size limits, seasons and retention—confirm the latest guidance before fishing
• Practice good fish care (especially wrasse, which are vulnerable to poor handling): unhook quickly, minimise air exposure, and release in calm water where possible
