Read the water before you fish it. Charts show drop-offs, reefs, channels, and current edges — fish hold where structure meets food, so mark those and fish them on the right tide. Learn your tides and conditions: plenty of species switch on around the tide change, and wind and swell decide whether a spot is even fishable. Watch for working birds — birds over bait means predators under bait. And ask at the local tackle shop: they won't hand you their best mark, but they'll point you at water that's producing this week.
Then put in the hours and log everything. Most anglers forget what actually worked — the tide, the wind, the time of day. The Fishing Codex app is a free logbook built for exactly this: it saves your spots and catches with the conditions at the moment of capture, and it works fully offline, so a dead patch of reception never costs you a mark.
