Surf's Up!

"With 150 live-streaming cameras positioned at key surf spots around the globe and a sophisticated software system designed to predict wave conditions even a week in advance, Surfline.com is a surfer's paradise. That's why 1.5 million unique web users-and 500,000 more on mobile-use the site every month."

If you surf, this seems like a must have app. Check out surf height, weather, 2 day forecasts, tide levels and a variety of other must know bits of information to catch that perfect wave. And you can do it all from your iPhone or iPod Touch. I'm too scared of sharks (I watch Discovery Channel, I know things) to try surfing but if you do, you may want to have this at your disposal. Best of all, it's free!
