Only a forecast, but I don't recall seeing a 'black' swell in the SW approaches all last winter. Long period (19secs in west Cornwall) as well.
Porthleven will be packed if that come's about. No doubt will news reporters close to the waters edge telling the listening public there are hoards of stupid people close to the waters edge.
Well of course there will be, what a photo opportunity!

Just coming off Spring tides too but still quite high.
Could be southerly gale which is not good for Wembury.

Indeed,
I'm probably telling you something you already know, but storm surge forecasts are available for Plymouth. Giving forecast variances from the Astronomical tide.
Offshore winds in Plymouth for the next couple of days. No data freely available for the north Cornish coast sadly.

0.5 m above astronomical tide predicted here.
So on top of Spring tides in the morning will give a bit more coastal erosion.

On top of which a swell height peaking near 30ft coming into Mount's Bay.
Looks pretty bad to me. Sandbags out along the prom.
Praa Sands for tomorrow, the big powerful long period swell being close to high tide. There will be wave setup surges on top of the model forecasts, which don't take into account the affect of surges associated with big wave sets, the time period is too short, typically 2-3 minutes.
Looks pretty bad to me. Sandbags out along the prom.
