But in the event the tidal surge was not as high the 14.15 metres (46 feet) predicted, and a tiny sliver of causeway no more than a few metres wide resisted the surge of water pushed by the moon's huge gravitational pull on the sea.
Saturday's tide on the long, sloping estuary of the River Couesnon could, however, go higher, although scientists said low air pressure may have lessened the phenomenon.
The bay on the coast of Normandy has some of the strongest tides in the world.
Police had difficulty holding back crowds eager to get a picture of the scene in the final minutes before the surge on Friday evening, with the tourist hotspot lit up as night fell with 60 spotlights for the occasion.
Similar surges are predicted along the coasts of Britain and the Netherlands over the weekend.
