Very Large Atlantic swell

Postby Graham Easterling » 2013 Oct 25, 16:07

The large area of low pressure sitting off Newfoundland/Southern Greenland, is continuing to generate a large swell. Theres quite a fair sized area to the WSW of Ireland forecast to have swells in excess of 40' on Saturday.

This large swell is forecast to reach Cornwall on Sunday, with waves peaking at 18'-28' at Sennen near Land's End! I'm hoping the wind isn't too strong on Sunday during daylight hours as there may be some quite spectacular surfing waves on the north Cornwall coast where the wind's offshore. Apart from the height of the WNW swell, the period will be close to 20 secs. See http://magicseaweed.com/Sennen-Surf-Report/4/

By the early hours of Monday, assuming the forecast track of that depression is correct, there will be a secondary swell from the SW of 15' and 11secs . Scroll down & click the '!' against 6am monday for a complete swell breakdown.

UPDATE 26/10 -
18-29' forecast for noon Sunday
Approx 20' at noon Monday

UPDATE 27/10
Swell reached 24' at Sevenstones. Breaking waves > 20' at Sennen.
