I had a great South Sound beach mostly to myself about 12 years ago, and I learned a lot while fishing it at different times/tidal stages. The only relative constants I found were: *That during full daylight, the fishing was much more productive two hours before and (especially) after high slack, when the food that grew in the tide pool began to wash out with the ebb. *That fishing was ALWAYS more productive at dusk, and usually at dawn. *That fish took up station in very nearly the same locations with each tide exchange. *That fishing sucked during daylight for the couple of days preceding a full moon (but often got very interesting at dark). *Pile worms made the cutthroat behave very strangely, and despite the audible slashing happening all around during a pile worn appearance, it was very difficult to hook fish during one. *That there were no absolute constants. Totally different take on trout fishing in the salt. Rivers and lakes are much more consistent, but hitting the salt right makes for fast, furious fun.
