Imagine being out exploring new islands, not realizing its low tide. You setup camp for the night on an island that's relatively flat and close to current sea-level. Then while you're sleeping the tide comes in and washes your whole camp out to sea...

Come to the beach here in Bordeaux (well, on the coast) and see tourists set up their stuff at low ebb but forgetting they have to watch out for the flood.

There's an island near me that has a pedestrian causeway at low tide. There are huge signs warning to check tide times or get cut off, but still people don't get it.

Cap Ferret but arcachon with the Pilat Dune works too!

if you are exploring islands you probably have a solid idea of how tides work.

You probably should, but that doesn't mean you do. It's not like anyone makes you take a quiz to go wander around outside.

Plenty of people get themselves into trouble all the time exploring places/things they know nothing about.
