Thursday Weather: Wind & Wave Watch

Weather forecast for Thursday September 20, 2012 Location: Klitmøller, North West Jutland, Denmark Time of Forecast: Wednesday September 19, 2200 CET (local time) Wind Direction: Westerly Wind Speed: 11-18 knots, gusting 20 Wave size: 1.5-2.4 metres Water temperature: 14 degrees Weather: Overcast with a chance of rain Temperature: 13 degrees

The forecast suggests any wind that is good enough to complete the super final, between Thomas Traversa and Philip Köster, may have disappeared by early Thursday morning at around 0700 local time. It will decrease throughout the day and there is almost no wind forecast for Friday. But a solid northerly wind of 20-22 knots is forecast for Saturday afternoon, which should allow a Cold Hawaii champion to be crowned.

“It’s like a wind machine here,” Duncan Coombs, the PWA head judge, said. “We just don’t know. There’s potential tomorrow but I think we’ll just have to wake up and see.”

Editor’s notes:

Robert Sand, event manager, Danish wave champion 2003-05 and Klitmøller windsurfer for 25 years on what makes Cold Hawaii:

Cold Hawaii is special because it has a lot of different surf spots that cater for any wind and wave direction.

The open water from the North Sea and North Atlantic draws in the low pressure systems that gain momentum as they travel across the top of the British Isles and then hit our coast. Once the winds start pushing in from the west they build up in the deep waters of the North Sea, and join forces with the North Atlantic swell that hits our steep coastline, so the waves jack up.

On a typical day there is a strong south-westerly wind with waves breaking on the crescent-shaped reef just off the beach. The reef creates a breakwater so windsurfers can get in out easily from the shore. Then beyond the reef the wind increases in the more open water, with the large breaking swells acting as massive water ramps to jump high, forward loop and ride the giant waves. On an average day the wave's summit can be as high as 2-3 metres, but at it's best we have seen mountainous waves as big as 6m. As a result of the powerful brisk North Sea south-westerlies gusting up to 50 knots and colossal seas the windsurfers call this Cold Hawaii.
