The current high tide is not that big astronomically, but is higher in Penzance than I observed at any time last winter, and higher than it was during then red coastal flood warning for Penzance a few weeks back. (We currently have an orange warning.)
This is the real time data from Newlyn
https://www.ntslf.org/data/realtime?port=Newlyn , but that's only half the story, there are some wave setup surges which raise the level significantly for a while.
I've just got back home after having tried to get along the prom, expecting to see it coming over in the normal way.
There is some depth of water over the bottom of the Abbey slip, up to the front doors of the houses. In the harbour the sea is washing into the car park & up to the door of the Harbourside cafe. The police had closed the prom which is a mass of water & seaweed, directed the traffic up a narrow 1 way street (not the best option,) and caused traffic chaos. Anyway, I'm back now!
All this despite the wind not being that strong, and the waves not that big, but the direction the weather is coming from has made the tide exceptional, forget what the tide table says!
