The high tides are an exceptional natural phenomenon to discover on the Normandy coast. The spectacle of the unleashed waves crashing on the seawall is breathtaking. See you on the Côte de Nacre, from Courseulles-sur-Mer to Ouistreham, for the next spring tides.
Where to watch the high tides on the Côte de Nacre ?
- from the wooden jetty at Courseulles-sur-Mer,
- from the croisette at Bernières-sur-Mer, at the eastern end of the sea wall,
- from the terrace of one of the restaurants in Saint-Aubin-sur-Mer,
- from the high dyke at Langrune-sur-Mer, next to the first aid post,
- at the foot of the fishermen’s jetty in Luc-sur-Mer.

Explanation of the tidal phenomenon
Our ancestors believed that the gods governed the tides. Scientific work over the centuries has established that this phenomenon is due to the attraction of the moon and the sun on our planet earth. It is the combined effect of universal gravitation and centrifugal force that causes the water to rise or fall.
A term to remember when talking about tides : tidal range.
What is tidal range ? The tidal range is the difference between the high and low tide levels. It is used to evaluate the amplitude of the tide. The tidal range is measured by the tidal coefficient. The greater the amplitude, the greater the tide. We speak of a large tide from a coefficient of 90.

The sea descends for 6 hours and then remains at slack water for about 30 minutes. Then it rises again for 6 hours. There are 2 full tides a day : the sea is therefore high twice a day and low twice a day.
Where to fish for shellfish in Calvados ?
The Côte de Nacre, located between Courseulles-sur-Mer and Ouistreham, is a particularly popular spot for shellfishing.
For SHELLFISH (razor clams*, clams, cockles, winkles…), choose Courseulles-sur-Mer, Hermanville-sur-Mer or Colleville-Montgomery where the beaches are sandy. Each person can collect up to 5kg of shellfish, whatever the species concerned, while respecting the minimum size of the catch.
The rocks of Calvados located between Bernières-sur-Mer and Lion-sur-Mer are well supplied with CRUSTACES (curlers, bouquets, grey shrimps, crabs…). The fishing of shellfish is permanently authorised on the Calvados coast. However, bouquet fishing is closed from 1 March to 30 June inclusive. It is also absolutely necessary to respect the sizes for a sustainable and responsible fishing !
For MUSSELS, choose the Pointe du Siège in Ouistreham. Collection is authorised from Monday to Saturday and every day on the rest of the Côte de Nacre, except for a temporary ban for health reasons.

Since 1950, the Benoist family has been breeding this oyster on the table in Asnelles. It is then matured in clear water in the basins located just beside Juno Beach, in Courseulles-sur-Mer.
Thrills and fresh air
When the tide gives way to this large expanse of sand, the favourite activity of the “sailors” is sand yachting. In summer and winter alike, this water sport combines technique and thrills.
The Courseulles-sur-Mer sailing school offers first flights of sand yachts for children and adults.
