Getting an idea before heading out...

I don't believe it's been posted her on WW before, but forgive me if it has been passed along. Prior to going out on the water, I like to try and get a perspective on weather condition. Water temp and air temp are great, but sometimes wind gust gets lost in the excitement of getting out on the water. I found this link while doing a project in an Environmental Science class: http://hint.fm/wind/. I thought it was cool, as well as interesting, so I thought I would pass it on. If all else fails, you can at least get mesmerized in the diagram.
