Hard to put some perspective on this. But that island is about 90ft tall at its peak Anyway, big churning sea today. despite the warnings, there were several rescues last night from people not taking heed of the advice to stay away from the water
The second pic is a zoomed in shot of the first. Those waves are breaking on a reef about a mile offshore. probably 20-25ft waves
Not my pic (obvs) but this gives a better idea of the size of the waves down here today. please log in to view this image
Been a few people plucked out today. Mainly holiday makers who got caught out by the spring tides. Coastguard heli had to winch somebody off of a rock after they clambered onto it to 'get a better view' and then got cut off by the tide.
