Summary

Long-period west swell, but windy in many places

Best bet

Northwest Spain

Synopsis at 00:00 UTC

Today’s chart shows a moderate-strength low pressure centred about 300 miles west of Ireland, moving west and weakening, expected to disappear over England by Sunday. Another system, presently just off Newfoundland, is expected to follow in the path of the first one, expected about 800 miles north of the Azores by Sunday, with a strong westerly fetch on its southern flank producing a pulse of long-period west swell. To the south there is a high between the Azores and Madeira, drifting steadily east. The upper airstream is moderate, with a ridge building through the middle of the North Atlantic. Local pressure gradients are mostly weak.
NAO index (large positive values usually mean potentially good surf): +20 mb

Area forecasts

Southwest Wales

Friday:
Good-quality long period swell, around four or five feet at exposed spots, but hampered in many places by fresh gusting strong southerly winds

Saturday:
The swell continues, with conditions cleaning up, around four or five feet with moderate west-northwest winds

Sunday:
The swell weakens, down to three feet or so, with conditions remaining fairly clean in light west or south-westerlies

North Devon and Cornwall

Friday:
Good-quality west-southwest swell, up to six feet or more at exposed spots in the far west, but with fresh to strong south-southwest winds

Saturday:
The swell continues, cleaning up at southwest-facing spots as winds veer northwest, light becoming moderate; wave heights up to six feet at the most exposed spots

Sunday:
Wave heights decrease to three or four feet on average, and conditions are fairly clean in most places, with no wind or light northerlies

South Coast of England

Friday:
Long-period swell, up to four feet or so at westerly exposures, mixed with local windseas generated by fresh south-westerlies, backing south later

Saturday:
The swell continues, around three or four feet at westerly exposures, smaller elsewhere, with light southwest winds, perhaps moderate later

Sunday:
The swell drops to below three feet everywhere, with light variable winds at first becoming light southwest later

East coast of England

Friday:
Small north swell with fairly good conditions in fresh southwest winds; wave heights up to three feet at northerly exposures, smaller elsewhere

Saturday:

Sunday:
Very small or flat in most places, with light northeast winds, veering east later

North Coast of Scotland

Friday:
Small west swell, perhaps up to three feet at exposed swell-magnets, with moderate southerly winds becoming fresh to strong west later

Sunday:
A small northwest swell arrives, around three feet or so at exposed spots, with moderate westerly winds becoming fresh southeast later

Northwest Ireland

Friday:
Small, fairly clean west swell, up to four or five feet at westerly exposures, much smaller elsewhere, with moderate southerly winds

Saturday:
The swell drops to around three feet or so at westerly exposures, much smaller elsewhere, with conditions becoming choppy in many places with fresh northwest winds

Sunday:
The swell weakens and becomes very mixed, averaging around three feet, with moderate becoming fresh southerly winds

Southwest Ireland

Friday:
Average to good quality west-southwest swell, perhaps exceeding eight feet at exposed reefs, with fresh southerly winds

Saturday:
The swell continues, around six feet or so, with winds veering fresh north-westerlies

Southwest France

Friday:
Good-quality west swell, up to six feet or so around Hossegor, with very clean conditions in light variable winds

Saturday:

The swell continues but is still hampered by moderate to fresh northwest winds; wave heights around six feet and lumpy

Friday:
Good-quality west swell, up to five or six feet at exposed reefs, with light gusting moderate easterly winds, backing north by late afternoon

Saturday:
Winds increase to strong or gale-force west-northwest, totally destroying the swell at most spots; wave heights a very lumpy eight feet or so

Sunday:
Winds veer northwest and decrease to moderate by afternoon, and the swell remains very lumpy, around six or seven feet at first, dropping steadily

Friday:
Good-quality west swell, up to five or six feet at westerly exposures, smaller elsewhere, with fresh gusting strong southwest winds

Saturday:
The swell becomes mixed with a short-period component, around five or six feet and very bumpy, with fresh westerly winds

Sunday:
The swell cleans up a bit, dropping to a peaky four or five feet on average, with windless conditions at first becoming light or moderate northeast later

Northwest Galicia

Friday:
Largish west swell, exceeding ten feet at westerly exposures, mixed with local windseas generated by strong southwest winds, veering west by afternoon

Saturday:

Sunday:
The swell drops further, to around four or five feet, but conditions improve in many places as winds change to moderate or fresh north-easterlies
