Mean Spring Tidal Range (m)

Tidal range is generally between 4 and 5 m; highest tidal ranges are found in the inner Solway Firth where the mean spring tidal range can be between 7 and 8 m. Tidal range is at a minimum in areas known as amphidromic points. One of these points occurs in Scottish waters between Islay and the Mull of Kintrye; another amphidromic point can be found in the north east of the North Sea. Tidal range decreases with distance offshore from the North East coast.
