Another Huge Swell - West Cornwall

Postby Graham Easterling » 2014 Feb 02, 13:31

1st Feb saw another huge swell arrive in west Cornwall during the afternoon. It was very similar in size to the 6th January event

6th Jan
Tide Height (Newquay) 7.2m
Peak Significant Swell Height (Sevenstones) 30ft
Wave Period (Sevenstones) 16-18 secs

1st Feb
Tide Height (Newquay) 7.5m
Peak Significant Swell Height (Sevenstones) 34ft
Wave Period (Sevenstones) 14 secs

Although the peak significant swell height and tide were higher this time, the slightly shorter period reduced the power of the swell, so there wasn't quite the extreme erosional effect of the 6th January storm. Also the wind was stronger this time which meant the swell was more blown out, the largest waves therefore breaking further offshore.

However there was still significant flooding, and some further damage along the north coast. Bude, Perranporth, Newquay & St Ives were all hit. In St Ives paramedics were called to treat a woman injured after the wind caught a window which hit her head while she leaned out to watch firemen pumping out her water-front house. It just awasn't her day!

A fishing vessel sank off Newquay. Sea conditions were such that the crew had to jump into the sea in order to be winched up to a helicopter. The vessel is now on the rocks near Porthcothan. ... z2sAdiESCy

The sea life aquarium at Newquay is now in a precarious position. ... z2sAdiESCy

I've also attached a picture of Sennen.

That's just a brief selection. The next real gale, MetO forecasting SE gusts >75mph for Penzance Tues PM, will be the worst yet for Mount's Bay, if it comes about.

Quite a winter!
