7.1 · Rocks · Cornwall
Rosemullion Head is a rocky headland on the north side of the Helford entrance, offering kelp-lined gullies, ledges and patches of clean sand in clear, relatively deep water. It fishes best on the flood into dusk through summer and early autumn, with wrasse and pollack tight to the rough ground and pelagic species moving through on settled days. The mark is exposed to easterly swells but is often fishable in light to moderate south-westerlies. Expect snags—use strong gear and rotten-bottom links. Access is via the South West Coast Path from nearby parking, with short scrambles to reach comfortable rock platforms.

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.

Rosemullion Head sits between Maenporth and the mouth of the Helford on Cornwall’s sheltered south coast, offering mixed rough ground, kelp beds and tidal seams. It’s a classic rock mark for wrasse and pollack with summer mackerel runs and a real chance of bass in the right conditions. The scenery is superb and, with care, it rewards mobile, lure‑led fishing and traditional float tactics alike.
This is a National Trust headland with coastal paths, small cliff-top fields and several goat-track descents to rock ledges. Access is straightforward in dry weather but can be slippery after rain and is not suitable for limited mobility.
The headland fishes as mixed rough ground into Falmouth Bay on the east and toward the Helford mouth on the west. Species shift with season and water clarity.
Mobile lure fishing and classic float tactics excel here; bottom fishing works but snag risk is high, so plan your end tackle accordingly.
Tide flow wraps around the point creating seams and eddies; clarity is often good after westerlies but drops quickly with onshore easterlies.
This is an exposed rock headland with steep, uneven approaches and no barriers. Plan your route in daylight and fish within your limits.
There are no facilities on the headland itself—come self‑sufficient with water, food and a first‑aid kit. Nearby villages and beaches offer basics.
Little adjustments make a big difference at Rosemullion—fish the structure, keep moving and match the water state.
General sea angling is permitted at Rosemullion Head, but regulations apply and some nearby waters carry additional protections. Always check the latest official sources before retaining fish.
