What makes a North wind so bad on Kentucky lake? Is it the current going against the wind? The forecast yesterday was 10 mph winds out of the north so I waited until 4 to put in hoping the main channel would die down. I was wrong. It wasn't the worst I have seen it, but I wasn't about to try it and break equipment. I know the lake runs north and south so the wind doesn't have a wind break out of the north, but a 10 mph south wind doesn't even compare to a north wind.
