30 August - A tide in Granville

Stuck in Cherbourg for replacing the cooling unit of the fridge, we spend the time of a tide in Granville, with my family.

The grand pavois in the church of the enclosed city.

The tide coefficient is 114, getting all inhabitants out for clam-picking.

With such tide coefficient, the amplitude of the tide is around 12 metres. The tide will take 6 hours to get these 12 metres of water back. During the third and fourth hour after the low tide, the water is getting 1 metre higher every 20 minutes. Regularly, people are trapped in rising waters and need to be rescued by helicopter. In fact, the helicopter flies everyday at the time of the rise, in order to send the signal to clam pickers that it is time to get back.
