I'm posting this through he BVI forum since there's been much discussion about swell directions when planning for overnight stops and various services folks use to watch for it. I got an email last night from Active Captain promoting the free service, windyty. Pretty cool. I've seen other animation overlays, but this is nice in bring several of them together. And you can click on the circles shown on the map to pull up additional charts and readings from that station - as well a web cams in the area. I found it interesting to watch the swell direction and how it can change just in a matter of a day or two. Not so sure if the colors truly match with the measurements shown on the right, though. Would love to hear thoughts from those that are much more experienced watching these forecasts.
