So if I’m paddling in a tidal river or narrow estuary and the tide is going out, there is a tidal current that draws me out to sea. Why isn’t one drawn further out to sea when in the ocean itself. The water level drops by the same amount (more-or-less) in both locations, but in one case I’m fighting a tidal current and in another case I’m not. Assuming for the moment that my premise is correct, I don’t logically get why there is a current in one case and not the other. My best guess is that my premise isn’t quite right and maybe one only gets noticeably pulled seaward with the outgoing tide when water from an incoming tide has accumulated in a large area and then gets flushed out through a narrow area (e.g., an inlet(/outlet) between barrier islands) - sort of like putting your thumb over the end of a garden hose to make the water come out faster. Is that it?
There must be at least some tidal current even at the beach though, right, because if the water level drops 6 feet, all that water that my kayak is resting on top of is going somewhere (out to sea).
