The conditions that actually matter
Ask five anglers what turns fish on and you'll get five answers: the tide stage, the moon and its solunar majors and minors, barometric pressure on the move, the wind laying down, the swell backing off, fresh rain colouring the water. Here's the honest bit — they can all be right, on their own water, for their own species. What loads the wharf on a spring tide flat does nothing up the estuary. There is no universal "good fishing day", and any app that pretends there is, is guessing.
