Severn Bore

High spring tides at this time of year result in the Severn Bore being larger. This tidal phenomenon is caused by incoming tides being increased in force by the narrowing of the estuary and then held back by sandbanks so that a wave sweeps right up the river.
It is a amazing to look out over a calm slow flowing river which suddenly becomes a torrent in the opposite direction sweeping upstream.
