Tidal flow direction around islands?

[Gary Busey]

I hope this isn't a stupid question and I'm not missing a basic rule of physics but...

If an island such as south Stradie for example, has it's tidal flow moving in and out of the Pin and the Seaway, does that mean there's an area half way down the island inland where the current could move north or south and will almost rise and fall without current?

Thanks.

Have had the same thought myself. Thinking logically there still has to be a current for the water to rise and fall. Those areas are going to have current but it won't be tearing in one direction but turbulent. Much easier to fish in than the current taking your bait at 4knots.

For any science nerds out there it would be fun to build scale topographical model and test it out with dyes in the water. Wouldn't know where to find it but I am sure plenty of computer modelling would have been done.

Yeah, you'd think if such a place exists around any islands, it'd be a good spot on a fast incoming tide, if 2 currents from different directions are hitting each other and stirring things up.

At a guess, I'd say the size of the area would depend on the size of the island and the underwater features. And the location could change with wind, temp, etc.

lol ive had the same question myself, if you head around to the southern part of tipplers passgae youll find theres very little movement so if such a meeting point exists this may be the place to start looking, plus its in the middle of both bars

Good to know.

I was hoping there'd be spots like this to try when the current is too strong elsewhere.

I'll check it out next time I'm in the area at half tide and see if I can find some still water.

Cheers.
