The tides are an exciting natural spectacle and a special experience for all North Sea holidaymakers and locals. The water level reaches a level of about three meters twice a day, then the mudflats are flooded. The water high is known as flood. Then the water pulls back again, then we have low tide. When the water has reached its lowest level, one speaks of low water.
The reason for ebb and flow is the attraction that the moon exerts on the water masses of the earth. The moon attracts water like a magnet. On the side of the earth facing the moon, a kind of water mountain forms in the sea. At the same time there is a flood on the side of the earth facing away from the moon.
