Mark-specific fishing decisions
Castwise does more than put fishing spots on a map. It compares each mark’s ground, orientation, depth, tide, wind, swell, safety and target species to help you decide where to fish and when to go.
A fishing mark is a specific place an angler may fish, such as a beach section, rock ledge, pier, harbour wall or estuary bank. Its ground, depth, structure, exposure and access affect which species it suits and when it fishes well.
Castwise provides public shore-fishing areas across the UK and lets anglers add their own custom marks. It scores those places against the selected time, target species and forecast conditions instead of presenting every spot as equally suitable.
No. Custom marks, exact coordinates and individual catch logs are not published. An angler can use a private mark for personal scoring without turning it into a public spot.
Castwise ranks suitable marks for a chosen time and target species using a deterministic engine. It explains why one option scores above another, but the result is forecast-based guidance rather than a catch guarantee or a substitute for checking access and safety.
The same forecast can suit two neighbouring marks very differently. An onshore wind may put useful colour into a surf beach while making an exposed rock ledge uncomfortable or unsafe. A rising tide may cover productive structure at one mark while cutting off the return route at another. Castwise evaluates the forecast in the context of the place rather than assigning one score to the whole coast.
Castwise considers useful mark context such as ground type, structure, water depth, coastal orientation, shelter, access and known hazards. Those characteristics are interpreted alongside tide stage and range, wind, swell, weather, season and the species you want to target. The exact weighting depends on the mark and species; Castwise does not publish the proprietary scoring formula.
A clean sand mark may be promising for flatfish or rays yet poor for a reef-associated species. Rough ground may suit wrasse, pollack or conger but demand different tackle. Selecting bass, for example, asks Castwise to rank the marks and windows for bass rather than for sea fishing in general. Start with the UK species guides or the bass fishing app page.
Public areas help anglers discover realistic places to investigate across the UK. Custom marks let an angler score a personal location without publishing it. Castwise recommendations never remove the need to verify legal access, parking, local restrictions, tide times and the actual state of the sea before a session.
Choose a time and, if useful, one or more target species. Castwise returns ranked marks with their forecast window, fishing potential, detected safety context and the factors behind the result. The aim is a defensible shortlist—where, when and what to target—not a promise that fish will be present.
