Re: Current - predictable?

Inshore is quite predictable, just consult tide tables. I'll assume you're talking offshore. In which case, offshore currents tend to be circular in motion after you get away from the shore far enough. The stronger the tidal flow, the stronger those circular currents will be. Moving several miles away from strong flow can land you in low flow areas. I have seen some maps of these circular currents, but not something very precise...on a lower resolution per say. I'm inclined to believe that they are somewhat stationary in position like eddies in a river with uneven bottom/shoreline but change according to tide strength much like would happen in a smaller observable micro environment.
I'm sure some more experienced commercial divers on here might be able to lend more.
