I traveled to Paris with my University and visited the UNESCO headquarters and walked through the Le Marais neighborhood which still has a strong Jewish presence. For the weekend I headed to  Mont Saint-Michel to witness the super tide that occurs once every 18 years.

Supertides are real!

"So in an ordinary year, the highest high tides and lowest low tides occur during spring tides near the equinoxes. But every once in a while — in particular, once every 18 years — you not only get spring tides right at one of the equinoxes, you get it coincident with a perigee Moon, and hence you get the maximum of all possible tidal effects: a supertide! And that’s when tidal flooding is most likely, and when this one French Abbey — Mount Saint-Michel — will flood like we just saw. Of course, the flipside of this is that in addition to the highest high tides, we also get the lowest low tides, and that’s spectacular in its own right!"

Once every 18 years, a French Abbey — Mount St.-Michel — becomes inaccessible, as the English Channel rises to such levels that the causeway that normally reaches it becomes engulfed by the surrounding waters. You might think this is due to the tides, where the Earth, Moon and Sun align, but then shouldn’t this happen twice a month, during the two Spring Tides? As it turns out, the effects are much more subtle, and involve the Moon’s elliptical orbit and the equinoxes as well, but when they all align, once every 18 years, a supertide is the result, and Mount St.-Michel becomes an island!

A European 'Supertide'

“Part of France's North Atlantic coast and southwestern England braced for their first giant tide of the millennium on Saturday as the alignment of the sun and the moon created an ocean surge not seen since the 1990s. This so-called "supertide" or "tide of the century," with surges up to 14 meters high, actually happens every 18 years. The high tides have turned France's famed Mont Saint-Michel into an island, and sent bore tide waves into England's River Severn, and the extreme low tides have exposed areas of beach and rock unseen since 1997.”
