A RARE five star bore was caught on camera in an aerial photo as the wave rolled upstream on the River Severn this morning.

Kevin and Sally Watkins had risen early to capture surfers riding the world’s second largest tidal wave on their drone quadcopter.

According to the Severn Bore website: ‘The shape of the Severn estuary is such that the water is funnelled into an increasingly narrow channel as the tide rises, thus forming the large wave.

‘As well as the width of the river decreasing rapidly, then so does the depth of the river also change rapidly, thereby forming a funnel shape.

‘Therefore as the incoming tide travels up the estuary, it is routed into an ever decreasing channel.

‘Consequently the surge wave or bore is formed.’
