I don't pay that much attention to them, I just go when I'm able to go. If I'm planning to go tomorrow morning and I happened to look at the solunar tables and the tables predicted it was going to be slow, I'd still go. And if the fishing turned out to be bad, then I'd have something to blame it on .
Back in my salmon fishing saltwater days, tide phases were very important as to where the fish would be, lots of current was generated by tidal conditions.
