Saturday is looking particularly bad for the north coasts of Cornwall & Devon. 

Here, in the far SW, NW winds are the direction which tend to be underestimate in forecasts, SW winds rather the reversre. No doubt down to the funelling of the winds around the Land's End (Penwith) peninsula. March 2008 being a prime example https://www.sennen-cove.com/10march08.htm

Currently forecasting gusts to around 80mph even in sheltered Penzance.

Just as well it's not spring tides. Swell forecast (in meters not feet!)

So a forecast swell of up to 8.3m off the tip of Cornwall and off the north coast near Perranporth, that's 27 feet. These are significant wave height forecasts, the biggest waves will be approximately 50% bigger. The waves have quite a long period of time to build, for the first time this Autumn/Winter.

On the south coast only the west facing side of the Lizard affected. Expect archive pics of Porthleven on the news.

Porthmeor beach, St Ives should be interesting at high tide on Saturday.
Good job it is not Spring tides as you say.

Wembury is sheltered from NW wind. No good for paddle boarding though. LOL.

Penzance is completely blown flat this monring, with a directly offshore F7-8. No trains at all

The north coast webcams which are operational have such a thick coating of salt, it's basicaly impossible to see what's happening in the really exposed spots. THere is a webcam in Sennen harbour, where if you enhance the picture you can see the breakwater, which is a big structure. Well the bit that isn't hidden by the sea. Lifeboat slip to the left gives some scale.

I'd be out there like a shot, but I've got caring reponsibilities today. I'll have to wait until social media photos. The news has the normal archive pictures showing large waves on the wrong coast.

So Cornwall Live (once a news channel, now like Devon live etc., purely exists for advertising - that's the parent company's job) runs with a train enetering Penzance

as the headline photo, when it's totally blown flat

A tale of 2 coasts where the news channels are totally misleading. Until they catch up and grab a few genuine photos from the web. The north coast is really wild. Significant wave height at Sevenstones' off Lands End, has been just >25' - so far.

In the old days there were reporters.
