Sometimes I really miss living on the coast. I grew up on the North Carolina coast, and our house was a short walk from the shore and less than two miles from the ocean. We could hear the sound of surf pounding along the beach at night, when the ocean waters were rough. And we could smell low tide (marée basse in French) — it was a fishy, seaweed smell.
You won't smell that when you look at this slideshow made up of photos I took at Portbail, in Normandy, but you'll see the evidence. It runs for less than a minute.
Depending on the cycles of the moon, the difference in water level between high and low tide at Portbail, 50 miles north of the Mont Saint-Michel and 15 miles east of the Isle of Jersey, can be about 30 feet (nine or ten meters). I think I'm reading that right on this web page.
On a very low tide at Portbail and other ports along the Normandy coast, all the boats are left sitting on the muddy bottom of the bay. Meanwhile, if I'm reading this web page correctly, the difference between high and low tide in Morehead City, N.C., where I came from, is only about four feet. Oh, there's also an ancient fortified church at Portbail...
