Porthselau

6.7 · Beach · Pembrokeshire

Porthselau is a small, sheltered sandy bay just inside St Davids Head, fishing as a classic Pembrokeshire rock-and-sand mark with easy access from the nearby car park and a short walk onto the beach. Most sport comes from casting into the deeper water and rough ground either side of the bay, with lighter tactics producing wrasse and pollack tight to kelp-covered rocks; it can be fairly calm in settled weather but tide run and swell from the headland can quickly change conditions.

Met Office 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.

· windows & tide

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.

Premium Mark Insight

Locked

Porthselau fishes best as a close-range rock-and-sand venue rather than a pure beach cast. The key is choosing the safest workable stance, then targeting kelp edges, darker gullies, rough margins and cleaner sand patches according to species. Slack water and the first push of the flood are usually the most useful windows, especially for wrasse, pollack, bass and lure or float work. Heavy swell, awkward tide run and drifting weed can quickly turn it from productive to frustrating or unsafe.

  • Know when to fish close instead of wasting casts into kelp.
  • Pick the right side of the bay for wrasse, pollack or bass.
  • Use the slack-to-flood window instead of fighting the tide.
  • Avoid the swell and weed conditions that ruin this mark.
  • Have a nearby backup plan before Porthselau turns unsafe.

Porthselau fishing guide

Practical access, seasons, methods, tides, safety and facilities for this mark.

Porthselau is a small, exposed inshore mark on the north Pembrokeshire coast, close to St Davids, where mixed ground and strong tide lines can bring fish within casting range.

    • It’s best thought of as a rough-ground venue with opportunities for bass, wrasse and pollack in summer, and codling/whiting with the odd ray or dogfish when conditions suit.
    • The fishing is often about timing: working the slack water and the first push of the tide, and choosing days with manageable swell and clear access.
    • Expect a “proper Pembrokeshire” feel: scenic but unforgiving, with weed, kelp and boulders that reward tackle discipline and careful footing.

The mark is on the Porthselau/Whitesands side of the St Davids peninsula, reached via local lanes and then on foot to the shoreline.

    • Approach is typically via nearby parking areas used by walkers and beachgoers; from there, follow established paths down to the shore.
    • Access can involve uneven steps/rocky descent, and the safest fishing is usually from more stable ledges or boulder platforms rather than the steepest sections.
    • In summer, expect more people around the broader area (especially if you’re close to popular beaches), so early/late sessions are quieter and safer for casting.

Porthselau’s mix of kelp, reef and deeper pockets gives you a genuine “mixed bag” prospect list across the seasons.

    • Bass: summer into early autumn, particularly after a bit of surf or colour in the water.
    • Wrasse (ballan and smaller wrasse species): late spring through autumn around kelp and rocky gullies.
    • Pollack and mackerel: summer; pollack tight to kelp edges, mackerel when shoals move in.
    • Codling/whiting: colder months can produce, especially after rough weather settles.
    • Dogfish, conger (occasional), and the odd ray/flatfish: possible depending on exact stance and sea conditions.

This is a venue where your method should match the ground: expect snags, weed and sudden depth changes, so simple, robust rigs and active fishing often outscore delicate setups.

    • Lure fishing: soft plastics, weedless presentations where possible, and hard lures worked along kelp edges for bass and pollack.
    • Float fishing / light ledgering: effective for wrasse and pollack in calmer conditions; fish close—often the takes are under the rod tip.
    • Rough-ground bait fishing: short snoods, strong hooks and abrasion-resistant leaders; crab, ragworm and fish baits are typical choices.
    • Uptide/longer casts (when feasible): if you can reach a clean patch beyond the worst kelp, you can present baits more effectively on the ebb/flow.
    • Tackle: bring spare leads and rigs; choose grippy footwear and consider a longer landing net/pole if your platform is above the water.

Tide and sea state make or break this mark; even on a calm day the current can be lively and the swell can wrap in unexpectedly.

    • Best tide phases: often the slack water and the first hour or two of the flood for lure and float work; bait fishing can pick up as the flow builds if you can hold bottom.
    • Sea colour: a touch of colour after a blow can help bass, while very clear water can favour careful presentations for wrasse/pollack.
    • Swell: moderate swell can fish well for bass, but heavy swell makes access and fishing platforms hazardous.
    • Wind: onshore winds can quickly roughen the water and limit safe stances; sheltered corners can still produce if you can find safe footing.
    • Weed: expect drifting weed in any swell—plan for it with stronger gear and by keeping baits/lures moving where practical.

This is not a “casual” rock mark: the shoreline can be slippery and the sea can surge, so treat it with full respect.

    • Footing: kelp-covered rock is extremely slick; cleated/rock boots are strongly advisable.
    • Swell and surge: avoid fishing low ledges if there’s any notable swell; waves can lift and flood platforms without warning.
    • Tide cut-off: some routes back can be compromised at higher water—always identify your exit route on arrival and keep checking it.
    • Solo fishing: not recommended on exposed rock; if you go alone, be extra conservative and tell someone your plan.
    • Landing fish: use a long net/gaf only where appropriate and safe; don’t overreach above swirling water.

Facilities are limited immediately at the rock mark, but you’re close to the St Davids area where you can stock up.

    • Parking: typically available in nearby public parking areas used by walkers/beach users (capacity varies by season).
    • Food/toilets: more likely in nearby visitor areas (and in/near St Davids) than at the immediate fishing stance.
    • Tackle/bait: best arranged in advance; options exist in the wider Pembrokeshire area but opening hours vary.
    • Phone signal: can be patchy around headlands—don’t rely on it for safety planning.

Fishing here is often about fishing “smart and close” rather than trying to punch huge casts into snaggy ground.

    • Read the water: look for kelp edges, darker gullies and any foamy seams—predators patrol these lines.
    • Travel light: a compact kit helps when negotiating rocky paths; keep hands free on the descent.
    • Time it: early morning or dusk can be excellent for bass; mid-day bright sun often pushes fish deeper/tighter to cover.
    • Rig discipline: keep traces short over rough ground, and don’t be afraid to step up leader strength to prevent cut-offs.
    • Respect other users: the wider area can be popular with walkers and beach visitors—choose safe casting zones and keep tackle tidy.

I’m not aware of a blanket rule that universally bans shore fishing at “Porthselau” specifically, but Pembrokeshire has areas with conservation designations and local restrictions that can affect what you can do and when.

    • Check on-site signage: especially near access points, car parks and paths—rules can change and may apply to specific sections of coast.
    • Protected areas: parts of the St Davids peninsula fall within designated conservation zones; restrictions may exist on bait collection (e.g., crabs/shellfish), species retention, or certain activities.
    • Byelaws and minimum sizes: apply to many species—verify current Welsh/Local Authority/NRW guidance before keeping fish.
    • Seasonal sensitivities: avoid disturbing wildlife and nesting areas; if asked to move by wardens/land managers, comply and relocate.
    • If in doubt: consult Natural Resources Wales and local Pembrokeshire coastal/byelaw information, and follow the most restrictive guidance you find.
