I can't honestly recall a similar experience. I've just negotiated my way back to St Mildred's Bay from West Bay, using the lip of the sea wall - pictured - where it connects to the cliffs. The sea surge is so intense that waves are rolling over the promenade and threaten to wash any careless passer-by into the sea.
I took the photo just after I jumped to safety to avoid the wave that preceded it.
If you have a beach hut in West Bay, best check on it. I have asked the council to try and help push No10 back into position as it has floated to the edge of the promenade and risks floating away.
It occurs to me that sea levels are higher than they were when I was a boy and along the promenade, there are scattered fragments of concrete where the waves have fractured lumps away from the edge.
A great view of the tidal action however from the cafe in West Bay and see the video that Michael Child shot of Ramsgate, below:
