The Severn Bore is one of Britain’s few truly spectacular natural phenomena. It is a large surge wave that can be seen in the estuary of the River Severn, where the tidal range is the 2nd highest in the world, being as much as 50 feet (approx. 15.4m). It is very popular with surfers who like to try and ride the wave.
As many as 60 bores occur throughout the world where the river estuary is the right shape and the tidal conditions are such that the wave is able to form. We are so lucky to be able to watch this here in Gloucestershire.
Spring time often sees some of the largest waves. The best and safest places to watch are at Newnham, The Severn Bore Inn, Stonebench, Minsterworth Church and Over Bridge but please be prepared for crowds and stand back behind the walls, never go onto the banks of the river.
The highest expected tidal waves are categorised by star ratings. A five star tide is the highest. During April & May 2017 there are not any five stars but there are some three stars to look out for on the evening of the 27th & 28th April and 26th & 27th May.
