Synopsis at 00:00 UTC

Today’s chart shows a moderate-strength high pressure system over the North Sea, drifting south, expected over Biscay by Sunday; a weak cut-off low drifting around just south of the Azores, and two stronger lows in the far north either side of a high over the Greenland ice sheet, both moving steadily east. There is a moderate westerly fetch south of Iceland generating some swell for west and northwest-facing spots. The upper airstream is fairly strong and meanderless but quite northerly-orientated. Local pressure gradients are weak in most places.
NAO index (large positive values usually mean potentially good surf): +15 mb
