A new coastline to explore
5 coastal counties now covered: Kent, East Sussex, West Sussex, Hampshire, and the Isle of Wight.
6.5 · Breakwater · East Sussex
Brighton Marina West Arm is a long, engineered breakwater mark reached on foot from the marina complex, offering elevated fishing over deep, sheltered water and the marina entrance approaches. It is most productive in calmer conditions for summer pelagic fish and bream, with mixed bottom-fishing opportunities into autumn and winter; check current marina access rules and avoid fishing in rough seas or high winds.

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.

Brighton Marina West Arm is a substantial, deep-water breakwater mark on the eastern side of Brighton, valued for its access to open sea and mixed rough ground. It can produce a broad range of Sussex species, but it is an exposed venue where sea state, wind and any access restrictions matter more than the tide alone.
The West Arm forms part of Brighton Marina's western breakwater structure, reached from the marina area rather than from an isolated beach. Expect a walk along hard surfaces and potentially uneven, wet or algae-covered sections near the fishing positions.
The mark's combination of deep water, artificial structure and open-channel influence gives it a varied species list. What is present depends strongly on season, clarity, bait movement and the amount of swell.
Tackle choice should match the target species and the amount of rough ground directly below the wall. Carry more than one approach: a light outfit for surface activity and a stronger bottom-fishing setup for bait fishing.
Brighton Marina West Arm can fish through much of the tide, but the most productive window is usually determined by water movement and fish activity rather than a single universal state of tide. A manageable sea and safe footing should always be the first requirement.
This is not a forgiving mark in rough weather: hard concrete, deep water and wave exposure mean that a lapse in judgement can have serious consequences. It is generally unsuitable for anglers with limited mobility when conditions are anything other than calm, and unsuitable for unsupervised children.
Brighton Marina has far better nearby amenities than many Sussex shore marks, although they are not necessarily located on the arm itself. Treat the fishing area as a working/exposed structure and prepare before walking out.
A little observation pays dividends here. Watch the water for baitfish, birds, colour changes and the line where marina-influenced water meets the open sea, then adapt rather than repeatedly casting the same distance.
Do not assume that a well-known angling mark has unrestricted public fishing at every time. Brighton Marina's management, harbour operations, temporary works and posted notices take priority, so check the current position on arrival and do not fish if signs or staff prohibit it.
