All - windguru is showing a step increase in wave period and a shift to the north in wave direction, starting late Friday and lasting for 2 days, before snapping back into a more usual pattern. Anyone know what's causing this? Seems like a dramatic change. I wondered if it was an anomaly in their models, but it's shown the same thing for several days now. We plan to be at JVD through this period, and I was thinking about White Bay or Diamond Cay, but am now wondering if Great Harbour might be a more comfortable overnight. Thanks all!
