John, when I first started SRC ff a couple of years ago, the initial advice I received was: 1) always fish on the incoming tide, 2) always fish on the outgoing tide, 3) only the middle two hours of a fast tide, 4) the two hours before and after a peak tide. Well, that set me straight. :beathead: Further research, including Les Johnson's book, gave me a clue as to why the disparate advice: each beach seems to have a distinct tide phase it fishes best; explore and learn. From what I can tell, a good part of it has to do with the currents formed from a moving tide on the underwater structure, and how that impacts the presentment of bait fish to predator fish. But I have certainly experienced the hot yesterday / nothing today from SRC on the same beach, as they simply move around a lot. It seems to be the nature of the SRC fishing that you search a beach for a riser, a follower, a boil or a hit, or otherwise move on to another beach. I agree, there seems to be a factor involved with the low light / zooplankton cycle, as well as other factors (barometer drop, moon phase, etc.), but I never heard of anyone that has that figured out beyond an interesting point of discussion while the fishing was slow, or over beers. Every time you think you see a pattern, the exceptions destroy any correlation you try to make. In the final analysis, I have adopted the often heard mantra: "the best time to fish is when you can". I have had some of my best days fishing SRC when I went to the beach because I needed the time out, and everything was running against all of the tendencies I thought I had figured out, and stumbled into an incredible day of fishing. I do believe the elusiveness of SRC is part of what make them so captivating a quarry. I would hope to one day have a better understanding of it all than just the Zen-like, "it is what it is". Now that I've shared my un-enlightened position thoroughly, I can go back to work and maybe someone with lengthy experience can shed some light.
