Chesil Beach can be severely affected by significant storm events. Depending on the how strong the wind is and the way in which the wind direction varies, a storm can affect the beach in various ways. These include a major redistribution of the pebbles and overtopping of the beach. A major overtopping can cause flooding in Chiswell and/or the upper Fleet. If the water level in Lyme Bay rises due to a storm surge in the Channel water can flow through the beach and push out large cavities in the back of the beach known as canns.

In addition to storm events, the beach very occasionally experiences swell events. these can occur when the weather is calm. They are triggered by major Atlantic storms which push big swell waves up the Channel to impact on west-facing beaches such as Chesil. The last major swell event was in February 1979 when very large swell waves caused considerable overtopping of the beach with resulting flooding in Chiswell.
