I find tides quite interesting. My father would always say, the tide's coming in, or going out. This was evidently important if you wanted to catch fish. I don't like fishing. Along with it being ever so boring, I don't like to see fish gasping for oxygen once they are out of the water. I like my fish in a can or batter where I can ignore their suffering of a slow death.
Tides, yes, that was what I am talking about. Where is a big one? Funny that you have asked. Maybe outback explorer Red or local WA person Grace or traveller Diane have seen this, but no matter, there are very big tidal changes at a certain place in Western Australia. Correctly now perhaps, West Australia, a state within our great Commonwealth of Australia. You are waiting to hear about tides? I seldom write a post without a personal connection, however obscure at times.
David Attenborough featured the location on one of his shows, I believe. Let me see what I can find out about it.
It is near Derby, way up north in West Australia. I think that is pronounced as written rather than Darby. Ok, I have found Attenborough's clip on YT.
Talbot Bay is the exact location. The bay has two narrow openings to the Indian Ocean and the tidal water flows in and out these gaps with huge force. The highest world tides recorded are in Nova Scotia, but this place has the second highest in the world.
There can be a fourteen metre change in the water level in just four hours. To visualise, think of the height of a five storey building. I'm thinking of a couple of turbines to generate electricity. I can also imagine a lot of sea creatures get swept in and out if they are nearby. Your pooh stick would take off like a rocket.
Best you watch the You Tube clip.
