I am absolutely addicted to this site, Windyty.com. It shows you wind patterns live (maybe a 30 minute delay) for anywhere in the world. Above is peninsular Malaysia, where I live. Also, when you go to the site, note the controls on the lower right side – try clicking a few, like “Waves, Sea”, and see how the map changes. I’m totally hooked on this.
Here’s rhe same map, but now it’s showing waves (approximations of how rough or calm the seas are)! NOTE that you can zoom in or out in either map, or even move around, the same way you would with Google Maps.
