A new coastline to explore
5 coastal counties now covered: Kent, East Sussex, West Sussex, Hampshire, and the Isle of Wight.
6.2 · Beach · Cornwall
An exposed shingle-and-sand surf beach immediately east of Porthleven Harbour. It shelves quickly and forms shifting gutters and bars that hold fish on flooding and ebbing tides. Summer brings bass, mackerel and garfish close in; autumn–winter sees whiting and dogfish. Night sessions produce flatfish (sole, plaice, dab). Powerful Atlantic swell, rips and a steep bank make it hazardous in rough seas—avoid big-swell days and take extra care near Loe Bar.

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.

Porthleven Beach sits on the eastern side of Mounts Bay in West Cornwall, a long, steep shingle-and-sand surf beach running towards the notorious Loe Bar. It’s an exposed Atlantic mark that can be superb for bass and surf species when the swell and colour line are right. Expect classic Cornish conditions: powerful surf, shifting bars, and a mix of clean sand with rougher, kelpy patches near the harbour reef.
Getting to Porthleven is straightforward via Helston, with the beach a short stroll from the village and harbour area. Access is easy to moderate, but the steep storm beach and soft shingle can be tiring underfoot.
This is a classic surf and mixed-ground mark with seasonal variety. Expect bass-led fishing, with small-eyed rays and turbot as notable targets on the sand.
Both surfcasting and lure work produce here, with tactics tuned to the sea state. Mixed ground near the harbour reef calls for stronger tackle; the open sand fishes well with lighter rigs when weed allows.
This beach is very condition-dependent. A modest, building swell with some colour and a flooding tide is the classic bass scenario.
This is an exposed Atlantic beach with serious hazards. Treat waves, backwash and the Loe Bar stretch with extra caution.
Porthleven is a well-served fishing base with year-round amenities. Most facilities are clustered around the harbour and village centre.
Small changes in sea state make big differences here. Read the beach before committing your session.
UK and local rules apply—check current notices on-site and official sources before you fish. Regulations can change in-year.
