How to choose a shore fishing mark

Start from the species

Different species want different ground. Clean sand suits flatfish and rays; rough and reef ground suits wrasse, conger and pollack; mixed ground and structure hold bass. Decide what you want to catch, then look for marks whose ground and structure match. Each species guide lists the ground and structure that species favours.

Match the mark to the conditions

A great mark in the wrong conditions can be a poor choice. Onshore wind and swell may add colour but can make exposed marks unfishable or unsafe; offshore wind can flatten nearshore water but may create different risks, especially for inflatables, kayaks or anyone entering the water. Think about which way the mark faces, how sheltered it is, and whether today’s wind and swell help or hurt.

Read the tide for that mark

Some marks only fish on a particular state of tide — a gully that needs water over it, a bar that only produces on the ebb, a ledge that is only reachable low down. Knowing the tide state a mark wants is half the battle.

Judge safety before anything else

Before you weigh the fishing at all, ask whether the mark is safe today: does it cut off on the flood, is the swell washing the ledges, is the access treacherous in the dark? Good-for-fish is not the same as safe. Read our tide cut-off safety guide.

How Castwise helps

Castwise scores the marks in your range for your target species, filtering by the conditions and flagging safety separately, so instead of guessing you get a ranked shortlist with the reasoning shown. See how it works.

Sources and further checks

Conditions and rules change. Before a session, use the Met Office coast and sea forecast, check RNLI angling safety advice, and verify retention rules in the current UK MCRS table plus the authority for the water you fish. Sources reviewed 15 July 2026; see the Castwise editorial policy.
