Clarki,
I don't claim to know it all and only offered what I learned from fishing nearly every day and speaking with the locals who know the beaches better than I (this is how I know that 'my' beaches can be productive year round). I fish 4 different beaches and each one fishes differently than the other. Two fish extremely well during the lower low tide and the incoming tide, but not so great during high tide. Another fishes well during the incoming tide through high slack. The fourth seems to be fishing decently during an incoming tide. I tend to learn through practice, observation and by talking with those who I meet on the beaches I'm fishing. I may not be as experienced as you, but I think I've learned a fair bit about fishing the beaches that I frequent. I've learned enough that I'm able to be relatively successful. Have I learned everything? No way, not even close.
