What is a tide and swell fishing app?
A tide and swell fishing app helps shore anglers interpret moving water, wave height, wave period, wind exposure and safety risk together, rather than reading tide times and marine forecasts separately.
Tide, swell and shore decisions
Castwise is rolled out across the UK and ready to use for shore-fishing planning wherever you fish. Castwise interprets tide, swell, wind, terrain, species and safety context together so you can choose a better shore window, not just read a forecast.

Castwise is rolled out across the UK and ready to use for shore-fishing planning wherever you fish. Castwise scores tide stage, tidal range, swell height, swell period, wind direction, ground type, target species and safety context together for public and private marks.
No. A spring tide and building swell can improve raw fishing potential while increasing risk. The spring range itself is warning-only because nearby marks share it; mark-specific tide cut-off, exposed swell and access hazards can still reduce the recommendation. High risk requires acknowledgement, while critical risk or missing essential data blocks recommendation.
Tide and swell only make sense when they are matched to the mark and the species you are trying to catch.
Flood, ebb, slack water and the timing of high or low water change how food, colour and fish move through a mark.
Spring and neap tides change the strength of the run, access windows and cut-off risk.
Height matters, but period often decides how far waves run up a ledge and whether exposed ground is fishable at all.
Onshore wind can add colour and movement; too much wind or the wrong direction can make a mark unfishable or unsafe.
Surf beaches, kelp, reef, gullies, mixed ground and harbour edges respond differently to the same tide and swell.
Detected risks are listed separately, reduce the recommendation score where relevant, and can require acknowledgement or block recommendation.
