Well, I haven't heard about the other days but Saturday at Weymouth was a whiteout for round 1 of the BKSA as the sea mist rolled in and the wind was almost as low as the visibility.
You have to feel for the event organizers competing with the vagaries of the British weather.
Even less wind was expected for Sunday so I guess that the show just moves on to Brighton for 27th-29th May;
this has also been nominated as a European Kitesurfing Cup qualification event.
