A storm tide is a tide with a high flood period caused by a storm. Storm tides can be a severe danger to the coast and the people living along the coast. The water level can rise to more than 5 m (17 ft) above the normal tide. Compare to storm surge.
For the protection from storm tides, long and high dike systems have been built, especially in the Netherlands, northern Germany and Denmark. Storm tides are a regular occurrence in these areas; usually, there are several storm tides each Winter. Most of them do not cause significant damage.
