Weekend Surf Report 30th June - 2nd July

Report Date: Friday 30 June 2017

Summary

Messy, wind-driven swell, biggest in Biscay

Best bet

Northwest Spain

Synopsis at 00:00 UTC
Today’s chart shows a duel-centred low pressure system stretching between southern England and the Low Countries, with a strong north-westerly fetch on its western flank pumping some ragged swell down into Biscay. The system moves away quickly east over the next few days. The rest of the North Atlantic has fairly weak pressure gradients, with a large high over the Azores, expanding steadily eastwards towards France. The upper airstream is of average strength and shifted way to the north; local pressure gradients are moderate but strong in a few places.
NAO index (large positive values usually mean potentially good surf): +20 mb

Saturday:
The poor quality wind-driven swell continues, up to ten feet at exposed spots and extremely messy, with strong west-northwest winds
