No big swell but very astronomical high spring tides & low pressure resulted in overtopping at various locations, you'd need an amphibious vehicle to go along the road to the Abbey Slip behind Penzance harbour.
St Ives

Lucky there was no big swell or strong onshore wind. Not had a worse case scenario covering all the risk factors for a few years.
Railway line to St Ives was closed due to flooding near Lelant.
